A Calendar’s Day are Numbered

No photo description available.

by Captain Paul Watson

Tomorrow is the end of the world, except where I am at the moment, where it is now tomorrow and the world is still intact.

Australia, New Zealand and Asia seem to be doing well. No tsunami’s, massive earthquakes, exploding Krakatoas, the Earth has not split, and the oceans have not boiled over and a few billion humans continue to go about their silly business of slowly destroying the planet.

There has been no rapture and the fanatical Christians are still with us unfortunately. I have not heard of any of them being swept en mass into heaven. I’m still hoping the nut bars from the Westboro Baptist church get raptured. They can protest babies entering heaven there instead of Connecticut.

But what about the Mayans?

Ahh the Mayans. They did not do so well at predicting their own demise.

I remember August 27th, 1987. That was the day that the Aztec calendar came to an end. They also were not that good at prediction. They did not see the fall of their own empire until they heard Spanish voices in their streets.

We place a great deal of reverence for ancient civilizations forgetting that they were in fact quite primitive, although probably more intellectual in many ways than modern society, at least for the very few who could actually read and write. Without television, they actually had to read, well some of them anyways, and without the modern music industry people actually had to sing and listen to musicians in small venues.

For the most part, be they Europeans, Meso-American Indians, Asians or Africans a great deal of time and effort was wasted on superstition and fighting wars over superstitious beliefs. Kind of like the situation today really.

And one thing that has not changed is this ridiculous belief that humans have some sort of special insight into nature and reality. Astrology for example does not include the planets that were unknown at the time which pretty much knocks all the equations flat on their ass by virtue of the fact that planets that were actually there were not influencing anything because nobody knew they were there and once discovered they still remained absent from astrology because all the signs and symbols were established and not subject to change.

The Mayan Calendar like the Aztec Calendar is round. It really does not end, it just starts all over again.

The fact is that a calendar’s days are numbered.

It’s like all the hype and hysteria at the end of millenniums and the strange thing is that millenniums are based on random dates that have no meaning. The year 2000 is not the year 2000 for the Muslims, the Jews or the Chinese for example.

Humans do not and never have controlled nature, physics, or the future. Human vanity may wish otherwise but the reality is that humanity is simply one of billions of species that have inhabited the Earth and humanity has only been around for a tiny fraction of the Earth’s history. The Earth will be around for a few billion years after humanity has disappeared.

Instead of worrying about silly predictions, we should be concerned about what we are doing to ourselves and our children with escalating population growth and diminishing resources. This is where the end will come about, the end of civilization first followed by extinction of the human species. We will be eradicated by our own ecological stupidity.

When will this happen? That I cannot say. In twenty years, a hundred years, but it will happen unless we curb growth and end the wasteful consumption of the planet’s diminishing resources.

When the Oceans die, we die.

When there is no more fresh water, we die.

When there are no more forests, we die.

When the land dies, we die.

When diversity dies, we die.

Why did the Mayans and the Incas disappear?

They disappeared because their populations grew greater than their resource base. That is the real lesson they left us.

Am I an Anti-Natalist?

If children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence, or at any rate not take it upon himself to impose that burden upon it in cold blood?~ Arthur Schopenhauer 

I have been accused of being an anti-natalist. The accusations suggest my particular variety of anti-natalism is congruent with life as a serial killer. Because I do not appreciate being called such names without supporting evidence, I decided the issue was worth a quick etymological investigation.

The definition of natalism, according to the Merriam-Webster online dictionary, is “an attitude or policy favoring or encouraging population growth.” The definition includes no mention of serial killers. Indeed, the definition mentions no murder of any kind.

I decided not to have children of my own at the age of 19 years. At the time, it made no sense to me to bring another human into the world without his or her permission, particularly in light of the publication of Limits to Growth seven years earlier. It still makes no sense to me. So far, I have succeeded in my personal quest to avoid adding more people to Earth.

I explained the horrors of continued growth of the human population for more than two decades in college and university classrooms. Few students took my advice seriously. I learned to not be attached to the outcome of my efforts, in the classroom and beyond. I thank my students for serving as my teachers.

I dedicated my first book-length work of social criticism, Killing the Natives, “to those who selflessly stop at zero.” Based on the responses I subsequently received, you would have thought I was suggesting we murder all babies, human and otherwise. That was not my point.

I am no fan of continued growth of the human population. At more than 7.7 billion and growing rapidly, I think there are plenty of us.

I am no fan of death. I am no fan of extinction, human or otherwise.

I know I will die. I am pretty sure you will die. I know our species, Homo sapiens, will go extinct. The only serious questions about death and extinction involve cause and timing.

I am certain my own death and extinction of Homo sapiens will occur soon. I am still no fan of death. I am still no fan of extinction, human or otherwise.

Apparently I am an anti-natalist. Apparently, based upon logic, I need not apologize for donning this label.

Too many humans, combined with an astonishing rate of consumption, have brought us to the brink of extinction. Too late to turn back now, I do not judge, shame, or blame people for bringing more humans to life. I am an educator, not a judge.

What If We Stopped Pretending?

The climate apocalypse is coming. To prepare for it, we need to admit that we can’t prevent it.

“There is infinite hope,” Kafka tells us, “only not for us.” This is a fittingly mystical epigram from a writer whose characters strive for ostensibly reachable goals and, tragically or amusingly, never manage to get any closer to them. But it seems to me, in our rapidly darkening world, that the converse of Kafka’s quip is equally true: There is no hope, except for us.

I’m talking, of course, about climate change. The struggle to rein in global carbon emissions and keep the planet from melting down has the feel of Kafka’s fiction. The goal has been clear for thirty years, and despite earnest efforts we’ve made essentially no progress toward reaching it. Today, the scientific evidence verges on irrefutable. If you’re younger than sixty, you have a good chance of witnessing the radical destabilization of life on earth—massive crop failures, apocalyptic fires, imploding economies, epic flooding, hundreds of millions of refugees fleeing regions made uninhabitable by extreme heat or permanent drought. If you’re under thirty, you’re all but guaranteed to witness it.

If you care about the planet, and about the people and animals who live on it, there are two ways to think about this. You can keep on hoping that catastrophe is preventable, and feel ever more frustrated or enraged by the world’s inaction. Or you can accept that disaster is coming, and begin to rethink what it means to have hope.

Even at this late date, expressions of unrealistic hope continue to abound. Hardly a day seems to pass without my reading that it’s time to “roll up our sleeves” and “save the planet”; that the problem of climate change can be “solved” if we summon the collective will. Although this message was probably still true in 1988, when the science became fully clear, we’ve emitted as much atmospheric carbon in the past thirty years as we did in the previous two centuries of industrialization. The facts have changed, but somehow the message stays the same.

Psychologically, this denial makes sense. Despite the outrageous fact that I’ll soon be dead forever, I live in the present, not the future. Given a choice between an alarming abstraction (death) and the reassuring evidence of my senses (breakfast!), my mind prefers to focus on the latter. The planet, too, is still marvelously intact, still basically normal—seasons changing, another election year coming, new comedies on Netflix—and its impending collapse is even harder to wrap my mind around than death. Other kinds of apocalypse, whether religious or thermonuclear or asteroidal, at least have the binary neatness of dying: one moment the world is there, the next moment it’s gone forever. Climate apocalypse, by contrast, is messy. It will take the form of increasingly severe crises compounding chaotically until civilization begins to fray. Things will get very bad, but maybe not too soon, and maybe not for everyone. Maybe not for me.

ome of the denial, however, is more willful. The evil of the Republican Party’s position on climate science is well known, but denial is entrenched in progressive politics, too, or at least in its rhetoric. The Green New Deal, the blueprint for some of the most substantial proposals put forth on the issue, is still framed as our last chance to avert catastrophe and save the planet, by way of gargantuan renewable-energy projects. Many of the groups that support those proposals deploy the language of “stopping” climate change, or imply that there’s still time to prevent it. Unlike the political right, the left prides itself on listening to climate scientists, who do indeed allow that catastrophe is theoretically avertable. But not everyone seems to be listening carefully. The stress falls on the word theoretically.

Our atmosphere and oceans can absorb only so much heat before climate change, intensified by various feedback loops, spins completely out of control. The consensus among scientists and policy-makers is that we’ll pass this point of no return if the global mean temperature rises by more than two degrees Celsius (maybe a little more, but also maybe a little less). The I.P.C.C.—the Intergovernmental Panel on Climate Change—tells us that, to limit the rise to less than two degrees, we not only need to reverse the trend of the past three decades. We need to approach zero net emissions, globally, in the next three decades.

This is, to say the least, a tall order. It also assumes that you trust the I.P.C.C.’s calculations. New research, described last month in Scientific American, demonstrates that climate scientists, far from exaggerating the threat of climate change, have underestimated its pace and severity. To project the rise in the global mean temperature, scientists rely on complicated atmospheric modelling. They take a host of variables and run them through supercomputers to generate, say, ten thousand different simulations for the coming century, in order to make a “best” prediction of the rise in temperature. When a scientist predicts a rise of two degrees Celsius, she’s merely naming a number about which she’s very confident: the rise will be at least two degrees. The rise might, in fact, be far higher.

As a non-scientist, I do my own kind of modelling. I run various future scenarios through my brain, apply the constraints of human psychology and political reality, take note of the relentless rise in global energy consumption (thus far, the carbon savings provided by renewable energy have been more than offset by consumer demand), and count the scenarios in which collective action averts catastrophe. The scenarios, which I draw from the prescriptions of policy-makers and activists, share certain necessary conditions.

The first condition is that every one of the world’s major polluting countries institute draconian conservation measures, shut down much of its energy and transportation infrastructure, and completely retool its economy. According to a recent paper in Nature, the carbon emissions from existing global infrastructure, if operated through its normal lifetime, will exceed our entire emissions “allowance”—the further gigatons of carbon that can be released without crossing the threshold of catastrophe. (This estimate does not include the thousands of new energy and transportation projects already planned or under construction.) To stay within that allowance, a top-down intervention needs to happen not only in every country but throughout every country. Making New York City a green utopia will not avail if Texans keep pumping oil and driving pickup trucks.

The actions taken by these countries must also be the right ones. Vast sums of government money must be spent without wasting it and without lining the wrong pockets. Here it’s useful to recall the Kafkaesque joke of the European Union’s biofuel mandate, which served to accelerate the deforestation of Indonesia for palm-oil plantations, and the American subsidy of ethanol fuel, which turned out to benefit no one but corn farmers.

Finally, overwhelming numbers of human beings, including millions of government-hating Americans, need to accept high taxes and severe curtailment of their familiar lifestyles without revolting. They must accept the reality of climate change and have faith in the extreme measures taken to combat it. They can’t dismiss news they dislike as fake. They have to set aside nationalism and class and racial resentments. They have to make sacrifices for distant threatened nations and distant future generations. They have to be permanently terrified by hotter summers and more frequent natural disasters, rather than just getting used to them. Every day, instead of thinking about breakfast, they have to think about death.

Call me a pessimist or call me a humanist, but I don’t see human nature fundamentally changing anytime soon. I can run ten thousand scenarios through my model, and in not one of them do I see the two-degree target being met.

To judge from recent opinion polls, which show that a majority of Americans (many of them Republican) are pessimistic about the planet’s future, and from the success of a book like David Wallace-Wells’s harrowing “The Uninhabitable Earth,” which was released this year, I’m not alone in having reached this conclusion. But there continues to be a reluctance to broadcast it. Some climate activists argue that if we publicly admit that the problem can’t be solved, it will discourage people from taking any ameliorative action at all. This seems to me not only a patronizing calculation but an ineffectual one, given how little progress we have to show for it to date. The activists who make it remind me of the religious leaders who fear that, without the promise of eternal salvation, people won’t bother to behave well. In my experience, nonbelievers are no less loving of their neighbors than believers. And so I wonder what might happen if, instead of denying reality, we told ourselves the truth.

First of all, even if we can no longer hope to be saved from two degrees of warming, there’s still a strong practical and ethical case for reducing carbon emissions. In the long run, it probably makes no difference how badly we overshoot two degrees; once the point of no return is passed, the world will become self-transforming. In the shorter term, however, half measures are better than no measures. Halfway cutting our emissions would make the immediate effects of warming somewhat less severe, and it would somewhat postpone the point of no return. The most terrifying thing about climate change is the speed at which it’s advancing, the almost monthly shattering of temperature records. If collective action resulted in just one fewer devastating hurricane, just a few extra years of relative stability, it would be a goal worth pursuing.

In fact, it would be worth pursuing even if it had no effect at all. To fail to conserve a finite resource when conservation measures are available, to needlessly add carbon to the atmosphere when we know very well what carbon is doing to it, is simply wrong. Although the actions of one individual have zero effect on the climate, this doesn’t mean that they’re meaningless. Each of us has an ethical choice to make. During the Protestant Reformation, when “end times” was merely an idea, not the horribly concrete thing it is today, a key doctrinal question was whether you should perform good works because it will get you into Heaven, or whether you should perform them simply because they’re good—because, while Heaven is a question mark, you know that this world would be better if everyone performed them. I can respect the planet, and care about the people with whom I share it, without believing that it will save me.

More than that, a false hope of salvation can be actively harmful. If you persist in believing that catastrophe can be averted, you commit yourself to tackling a problem so immense that it needs to be everyone’s overriding priority forever. One result, weirdly, is a kind of complacency: by voting for green candidates, riding a bicycle to work, avoiding air travel, you might feel that you’ve done everything you can for the only thing worth doing. Whereas, if you accept the reality that the planet will soon overheat to the point of threatening civilization, there’s a whole lot more you should be doing.

Our resources aren’t infinite. Even if we invest much of them in a longest-shot gamble, reducing carbon emissions in the hope that it will save us, it’s unwise to invest all of them. Every billion dollars spent on high-speed trains, which may or may not be suitable for North America, is a billion not banked for disaster preparedness, reparations to inundated countries, or future humanitarian relief. Every renewable-energy mega-project that destroys a living ecosystem—the “green” energy development now occurring in Kenya’s national parks, the giant hydroelectric projects in Brazil, the construction of solar farms in open spaces, rather than in settled areas—erodes the resilience of a natural world already fighting for its life. Soil and water depletion, overuse of pesticides, the devastation of world fisheries—collective will is needed for these problems, too, and, unlike the problem of carbon, they’re within our power to solve. As a bonus, many low-tech conservation actions (restoring forests, preserving grasslands, eating less meat) can reduce our carbon footprint as effectively as massive industrial changes.

All-out war on climate change made sense only as long as it was winnable. Once you accept that we’ve lost it, other kinds of action take on greater meaning. Preparing for fires and floods and refugees is a directly pertinent example. But the impending catastrophe heightens the urgency of almost any world-improving action. In times of increasing chaos, people seek protection in tribalism and armed force, rather than in the rule of law, and our best defense against this kind of dystopia is to maintain functioning democracies, functioning legal systems, functioning communities. In this respect, any movement toward a more just and civil society can now be considered a meaningful climate action. Securing fair elections is a climate action. Combatting extreme wealth inequality is a climate action. Shutting down the hate machines on social media is a climate action. Instituting humane immigration policy, advocating for racial and gender equality, promoting respect for laws and their enforcement, supporting a free and independent press, ridding the country of assault weapons—these are all meaningful climate actions. To survive rising temperatures, every system, whether of the natural world or of the human world, will need to be as strong and healthy as we can make it.

And then there’s the matter of hope. If your hope for the future depends on a wildly optimistic scenario, what will you do ten years from now, when the scenario becomes unworkable even in theory? Give up on the planet entirely? To borrow from the advice of financial planners, I might suggest a more balanced portfolio of hopes, some of them longer-term, most of them shorter. It’s fine to struggle against the constraints of human nature, hoping to mitigate the worst of what’s to come, but it’s just as important to fight smaller, more local battles that you have some realistic hope of winning. Keep doing the right thing for the planet, yes, but also keep trying to save what you love specifically—a community, an institution, a wild place, a species that’s in trouble—and take heart in your small successes. Any good thing you do now is arguably a hedge against the hotter future, but the really meaningful thing is that it’s good today. As long as you have something to love, you have something to hope for.

In Santa Cruz, where I live, there’s an organization called the Homeless Garden Project. On a small working farm at the west end of town, it offers employment, training, support, and a sense of community to members of the city’s homeless population. It can’t “solve” the problem of homelessness, but it’s been changing lives, one at a time, for nearly thirty years. Supporting itself in part by selling organic produce, it contributes more broadly to a revolution in how we think about people in need, the land we depend on, and the natural world around us. In the summer, as a member of its C.S.A. program, I enjoy its kale and strawberries, and in the fall, because the soil is alive and uncontaminated, small migratory birds find sustenance in its furrows.

There may come a time, sooner than any of us likes to think, when the systems of industrial agriculture and global trade break down and homeless people outnumber people with homes. At that point, traditional local farming and strong communities will no longer just be liberal buzzwords. Kindness to neighbors and respect for the land—nurturing healthy soil, wisely managing water, caring for pollinators—will be essential in a crisis and in whatever society survives it. A project like the Homeless Garden offers me the hope that the future, while undoubtedly worse than the present, might also, in some ways, be better. Most of all, though, it gives me hope for today.

New species related to humans discovered in cave

New species related to humans discovered in cave

JUST WATCHED

New species related to humans discovered in cave 01:15

(CNN)Ancient bones and teeth found in Callao Cave in the Philippines have led to the discovery of a previously unknown species related to humans called Homo luzonensis, according to a new study. The fossils belonged to two adults and one child who lived between 50,000 and 67,000 years ago.

This time frame means luzonensis would have lived at the same time as Neanderthals, Denisovans, Homo sapiens and the small-bodied Homo floresiensis. Like other extinct hominins, luzonensis is more of a close relative than a direct ancestor.
In 2007, a single foot bone was found in the cave and dated to 67,000 years ago. During excavations in 2011 and 2015, researchers found 12 additional hand and foot bones, including a partial femur and teeth, in the same layer of the cave. The researchers have named the new species luzonensis because of where it was found on the island of Luzon.
They are now the earliest human remains found in the Philippines. Previously, Homo sapiens remains were found on Palawan island and dated to between 30,000 and 40,000 years ago.
But what makes luzonensis different from other species? It’s all in the distinct premolar teeth, which vary considerably from anything identified in the other species belonging to the Homo genus.

The seven premolars and molars are smaller and more simplified than those of other species. Although some of the characteristics can be compared to Homo erectus and Homo sapiens, the teeth and jaw features remain distinct as far as the odd features they combine.
This factor, along with the fact that the researchers haven’t been able to remove DNA from the fossils, makes it difficult to determine where luzonensis fits, evolution-wise.
The two hand bones and three foot bones also show a unique anatomy.
Although separated by millions of years of evolution, luzonensis’ toe bone strongly resembles that of Australopithecus afarensis, or the famed “Lucy” fossil. Australopithecus lived between 2.9 million and 3.9 million years ago.
The finger bone also resembles that of Australopithecus, as well as early Homo species. The finger and toe bones are curved, like those of early hominins, likely suggesting that climbing was important to their lifestyle and survival.
“If you take each feature one by one, you will also find it in one or several hominin species, but if you take the whole combination of features, no other species of the genus Homo is similar, thus indicating that they belong to a new species,” said Florent Détroit, study author and paleoanthropologist at the National Museum of Natural History in Paris.

Complications in the evolutionary tree

Luzonensis presents a bit of a mystery because, as with the discovery of Homo floresiensis, previously unknown hominin species complicate the evolutionary tree. This also shifts the idea of which species migrated.
Given that Africa is regarded as the “Cradle of Life” and Homo erectus was found on the Indonesian island of Java, the idea is that erectus migrated out of Africa and helped disperse the species.
Floresiensis, nicknamed the “hobbit” species, have been found only on the island of Flores near Indonesia and were discovered in 2003. They lived between 100,000 and 60,000 years ago. And although they stood only around 3½ feet tall and had brains about one-third the size of a modern human’s, they made stone tools and hunted elephants.
It is believed that floresiensis was more diminutive in stature due to its island environment and limited resources. The same may be true for luzonensis, the researchers said.
Both of these species lived on islands that would have been reachable only by crossing the sea. And there is evidence of animal butchery on Luzon that dates back 700,000 years, but the researchers don’t know whether luzonensis is responsible.
The finding does build the case that hominins were already present on the island. They could have been luzonensis or the species descended from them, or perhaps they descended from another unknown group, the researchers said.
Seafaring could have happened by accident as they drifted on rafts or due to intentional navigation, the researchers said.
“We have more and more evidence that they successfully settled on several islands in the remote past in Southeast Asia, so it was probably not so accidental,” Détroit said. “Another important thing to have in mind is that you cannot successfully settle on an island with a single event of arrival of only few people, you need several individuals of course, and you need several arrivals, at least at the beginning, so that you have enough founders settled on the island.”

More exploration to come

So how did they evolve, and why do they share such varied characteristics with more ancient hominins? The answer may lie in more excavations and discoveries yet to be made on the islands of Southeast Asia.
“Our picture of homin evolution in Asia during the Pleistocene just got even messier, more complicated and a whole lot more interesting,” Matthew Tocheri wrote in an accompanying News and Views article. Tocheri, the Canada Research Chair in Human Origins at Lakehead University in Ontario, did not participate in this study.
The researchers are planning studying the biomechanical aspects of the fossils and how they may have moved, as well as more excavations of the cave or identifying new potential sites.
“As we can see now, Southeast Asia, and especially their islands, is a fantastic place for studying hominin evolution, and conducting fieldwork to find more sites with ancient archaeology and hominin fossils,” Détroit said.

Humanity Sleep-Walking Toward ‘Mass Extinction’

Politicians ignore the daily alarm bells in the science, whether it is melting Antarctica ice caps or the growing temperatures in the ocean

Next year, the British Government will host the UN Climate talks in London, known as COP26, which are the most important climate talks since Paris in 2015.

So for the next year, the UK will be a critical leader in the global fight against climate change.

For the UK to ask other nations to act, it also has to step up to the plate. And yet it is failing. Badly.

Today, the UK Government’s own experts, the Climate Change Committee (CCC) outlined in its annual report to Parliament, how “Our credibility in the COP26 Presidency rests on real action at home.”

But then they brutally concluded that the “UK action to curb greenhouse gas emissions is lagging behind what is needed to meet legally-binding emissions targets.”

The CCC noted that since June 2018, the British “Government has delivered only 1 of 25 critical policies needed to get emissions reductions back on track.”

Chris Stark, the CCC Chief Executive, said it would be prudent to not only prepare for a 1.5 degree rise in temperature, but also a 2 degree rise, and even a 4 degree rise.

Four degrees is widely seen as completely catastrophic by climate scientists.

So even a country like the UK, which has touted itself as a climate leader, is failing miserably. There is just no political will for any meaningful action.

The politicians ignore the daily alarm bells in the science, whether it is melting Antarctica ice caps or the growing temperatures in the ocean.

For example, earlier this week Daniel Rothman, professor of geophysics and co-director of the Lorenz Center in MIT’s Department of Earth, Atmospheric and Planetary Sciences, released a study in the Proceedings of the National Academy of Sciences examining how the rate at which carbon dioxide is currently entering the oceans could push us past a catastrophic threshold.

This threshold could happen slowly, or even suddenly, but when it does “the Earth may respond with a runaway cascade of chemical feedbacks, leading to extreme ocean acidification that dramatically amplifies the effects of the original trigger.”

As the press release from MIT regarding the study outlined: “Today’s oceans are absorbing carbon about an order of magnitude faster than the worst case in the geologic record.”

We are pumping so much carbon dioxide into the oceans that according to Rothman, today we are “at the precipice” of a threshold of “excitation.” If it occurs, “the resulting spike — as evidenced through ocean acidification, species die-offs, and more — is likely to be similar to past global catastrophes.”

If and when we cross this threshold, the carbon cycle is predicted to react “with a cascade of positive feedbacks that magnified the original trigger, causing the entire system to spike, in the form of severe ocean acidification.”

In other words, “if today’s human-induced emissions cross the threshold and continue beyond it, as Rothman predicts they soon will, the consequences may be just as severe as what the Earth experienced during its previous mass extinctions.”

Rothman’s new research comes two years after he predicted that a mass extinction event could take place as early as the end of this century.

Timothy Lenton, a Professor of Climate Change and Earth Systems Science at the University of Exeter, responded to the study by telling CommonDreams. “If we push the Earth system too far, then it takes over and determines its own response—past that point there will be little we can do about it.” Then we face runaway climate change leading into catastrophic mass extinction.

As with much of the news about climate change, this new research hardly got any press mention. The politicians sleep-walk on.

The magazine Mother Jones recently explored the issue of climate scientists who know “of a looming catastrophe but must struggle to function in a world that does not comprehend what is coming and, worse, largely ignores the warnings of those who do.”

The acutely powerful article details the daily distress of climate scientists, whose warnings are being ignored.

One scientist, Sarah Myhre, a former senior research associate at the University of Washington’s School of Oceanography, experiences “a profound level of grief on a daily basis because of the scale of the crisis that is coming”.

It is not that we didn’t know. It is not that the scientists didn’t warn us. We knew. But Exxonknew too. And it never wanted us to know the truth. And their decades-long denial campaign still has ramifactions today, as politicians refuse to act to the climate emergency that we are in.

Noam Chomsky: “Worship of Markets” Is Threatening Human Civilization

We live in dangerous times — no doubt about it. How did we get to such a state of affairs where democracy itself is in a very fragile condition and the future of human civilization itself at stake? In this interview, renowned thinker, Emeritus Professor of Linguistics at MIT and Laureate Professor of Linguistics at the University of Arizona Noam Chomsky, sheds light on the state of the world and the condition of the only superpower left in the global arena.

C.J. Polychroniou: Noam, looking at the current state of the world, I think it is not an exaggeration at all to say that we live in ominously dangerous times — and not simply in a period of great global complexity, confusion and uncertainty, which, after all, has been the “normal” state of the global political condition in the modem era. I believe, in fact, that we are in the midst of a whirlpool of events and developments that are eroding our capacity to manage human affairs in a way that is conducive to the attainment of a political and economic order based on stability, justice and sustainability. Indeed, the contemporary world is fraught, in my own mind at least, with perils and challenges that will test severely humanity’s ability to maintain a steady course toward anything resembling a civilized life.

How did we get to such a state of affairs, with tremendous economic inequalities and the resurgence of the irrational in political affairs on the one hand, and an uncanny capacity, on the other, to look away from the existential crises such as global warming and nuclear weapons which will surely destroy civilized life as we know it if we continue with “business as usual”?

Noam Chomsky: How indeed.

The question of how we got to this state of affairs is truly vast in scope, requiring not just inquiry into the origin and nature of social and cultural institutions but also into depths of human psychology that are barely understood. We can, however, take a much more modest stab at the questions, asking about certain highly consequential decisions that could have been made differently, and about specific cases where we can identify some of the roots of looking away.

The history of nuclear weapons provides some striking cases. One critical decision was in 1944, when Germany was out of the war and it was clear that the only target was Japan. One cannot really say that a decision was made to proceed nevertheless to create devices that could devastate Japan even more thoroughly, and in the longer term threaten to destroy us as well. It seems that the question never seriously arose, apart from such isolated figures as Joseph Rotblat — who was later barred reentry to the U.S.

Another critical decision that was not made was in the early 1950s. At the time, there were still no long-range delivery systems for nuclear weapons (ICBMs). It might have been possible to reach an agreement with Russia to bar their development. That was a plausible surmise at the time, and release of Russian archives makes it seem an even more likely prospect. Remarkably, there is no trace of any consideration of pursuing steps to bar the only weapons systems that would pose a lethal threat to the U.S., so we learn from McGeorge Bundy’s standard work on the history of nuclear weapons, with access to the highest-level sources. Perhaps still more remarkably, there has, to my knowledge, been no voiced interest in this astonishing fact.

It is easy to go on. The result is 75 years of living under the threat of virtually total destruction, particularly since the successful development of thermonuclear weapons by 1953 — in this case a decision, rather than lack of one. And as the record shows all too graphically, it is a virtual miracle that we have survived the nuclear age thus far.

That raises your question of why we look away. I do not understand it, and never have. The question has been on my mind almost constantly since that grim day in August 1945 when we heard the news that an atom bomb had wiped out Hiroshima, with hideous casualties. Apart from the terrible tragedy itself, it was at once clear that human intelligence had devised the means to destroy us all — not quite yet, but there could be little doubt that once the genie was out of the bottle, technological developments would carry the threat to the end. I was then a junior counselor in a summer camp. The news was broadcast in the morning. Everyone listened — and then went off to the planned activity — a baseball game, swimming, whatever was scheduled. I couldn’t believe it. I was so shocked I just took off into the woods and sat by myself for several hours. I still can’t believe it, or understand how that has persisted even as more has been learned about the threats. The same sentiments have been voiced by others, recently by William Perry [former defense secretary], who has ample experience on the inside. He reports that he is doubly terrified: by the growing risk of terrible catastrophe, and the failure to be terrified by it.

It was not known in 1945, but the world was then entering into a new geological epoch, the Anthropocene, in which human activity is having a severe impact on the environment that sustains life. Warnings about the potential threat of global warming date back to a 1958 paper by Hans Suess and Roger Revelle, and by the 1970s, concerns were deeply troubling to climate scientists. ExxonMobil scientists were in the forefront of spelling out the severe dangers. That is the background for a crucial decision by ExxonMobil management in 1989, after (and perhaps because) James Hansen had brought the grave threat to public attention. In 1989, management decided to lead the denialist campaign.

That continues to the present. ExxonMobil now proudly declares that it intends to extract and sell all of the 25 billion barrels in its current reserves, while continuing to seek new sources.

Executives are surely aware that this is virtually a death-knell for organized human society in any form that we know, but evidently it doesn’t matter. Looking away with a vengeance.

The suicidal impulses of the fossil fuel industry have been strongly supported by Republican administrations, by now, under Trump, leaving the U.S. in splendid isolation internationally in not only refusing to participate in international efforts to address this existential threat but in devoting major efforts to accelerate the race to disaster.

It is hard to find proper words to describe what is happening — and the limited attention it receives.

This again raises your question of how we can look away. For ExxonMobil, the explanation is simple enough: The logic of the capitalist market rules — what Joseph Stiglitz 25 years ago called the “religion” that markets know best. The same reasoning extends beyond, for example to the major banks that are pouring funds into fossil fuel extraction, including the most dangerous, like Canadian tar sands, surely in full awareness of the consequences.

CEOs face a choice: They can seek to maximize profit and market share, and (consciously) labor to undermine the prospects for life on earth; or they can refuse to do so, and be removed and replaced by someone who will. The problems are not just individual; they are institutional, hence much deeper and harder to overcome.

Something similar holds for media. In the best newspapers there are regular articles by the finest journalists applauding the fracking revolution and the opening of new areas for exploitation, driving the U.S. well ahead of Saudi Arabia in the race to destroy human civilization. Sometimes there are a few words about environmental effects: fracking in Wyoming may harm the water supplies for ranchers. But scarcely if ever is there a word on the effect on the planet — which is, surely, well understood by authors and editors.

In this case, I suppose the explanation is professionalism. The ethics of the profession requires “objectivity”: reporting accurately what is going on “within the beltway” and in executive suites, and keeping to the assigned story. To add a word about the lethal broader impact would be “bias,” reserved for the opinion pages.

There are countless illustrations, but I think something deeper may be involved, something related to the “religion” that Stiglitz criticized. Worship of markets has many effects. One we see in the origins of the reigning neoliberal faiths. Their origin is in post-World War I Vienna, after the collapse of the trading system within the Hapsburg empire. Ludwig von Mises and his associates fashioned the basic doctrines that were quickly labeled “neoliberalism,” based on the principle of “sound economics”: markets know best, no interference with them is tolerable.

There are immediate consequences. One is that labor unions, which interfere with flexibility of labor markets, must be destroyed, along with social democratic measures. Mises openly welcomed the crushing of the vibrant Austrian unions and social democracy by state violence in 1928, laying the groundwork for Austrian fascism. Which Mises welcomed as well. He became economic consultant to the proto-fascist Austrian Chancellor Engelbert Dollfuss, and in his major work Liberalismexplained that “It cannot be denied that Fascism and similar movements aiming at the establishment of dictatorships are full of the best intentions and that their intervention has, for the moment, saved European civilization. The merit that Fascism has thereby won for itself will live on eternally in history.”

These themes resonate through the modern neoliberal era. The U.S. has an unusually violent labor history, but the attack on unions gained new force under Reagan with the onset of the neoliberal era. As the business press reported, employers were effectively informed that labor laws would not be enforced, and the U.S. became the only industrial society apart from Apartheid South Africa to tolerate not just scabs, but even “permanent replacement workers.” Neoliberal globalization, precarity of employment, and other devices carry the process of destroying organized labor further.

These developments form a core part of the efforts to realize the Thatcherite dictum that “there is no society,” only atomized individuals, who face the forces of “sound economics” alone — becoming what Marx called “a sack of potatoes” in his condemnation of the policies of the authoritarian rulers of mid-19th century Europe.

A sack of potatoes cannot react in any sensible way even to existential crises. Lacking the very bases of deliberative democracy, such as functioning labor unions and other organizations, people have little choice beyond “looking away.” What can they hope to do? As Mises memorably explained, echoed by Milton Friedman and others, political democracy is superfluous — indeed an impediment to sound economics: “free competition does all that is needed” in markets that function without interference.

The pathology is not new, but can become more severe under supportive social and economic institutions and practices.

Yet, only a couple of decades ago, there was wild celebration among liberal and conservative elites alike about the “end of history,” but, even today, there are some who claim that we have made great progress and that the world is better today than it has ever been in the past. Obviously, “the end of history” thesis was something of a Hegelian illusion by staunch defenders of the global capitalist order, but what about the optimism expressed by the likes of Steven Pinker regarding the present? And how can we square the fact that this liberal optimism is not reflected by any stretch in the politico-ideological currents and trends that are in motion today both inside western nations but also around the world?

The celebrations were mostly farcical, and have been quietly shelved. On the “great progress,” there is serious work. The best I know is Robert Gordon’s compelling study of the rise and fall of American growth, which extends beyond the U.S. though with some modifications. Gordon observes that there was virtually no economic growth for millennia until 1770. Then came a period of slow growth for another century, and then a “special century” from 1870 to 1970, with important inventions ranging from indoor plumbing to electrical grids and transportation, which radically changed human life, with significant progress by many measures.

Since the 1970s the picture is much more mixed. The basis for the contemporary high-tech economy was established in the last decades of the special century, mainly through public investment, adapted to the market in the years that followed. There is currently rapid innovation in frills — new apps for iPhones, etc. — but nothing like the fundamental achievements of the special century. And in the U.S., there has been stagnation or decline in real wages for non-supervisory workers and in recent years, increased death rates among working-class, working-age whites, called “deaths of despair” by the economists who have documented these startling facts, Anne Case and Angus Deaton.

There is more to say about other societies. There are numerous complexities of major significance that disappear in unanalyzed statistical tables.

Realism, crystallized intellectually by Niccolò Machiavelli in The Prince,has been the guiding principle of nation-states behind their conduct of international relations from the beginning of the modem era, while idealism and morality have been seen as values best left to individuals. Is political realism driving us to the edge of the cliff? And, if so, what should replace the behavioral stance of governments in the 21st century?

The two major doctrines of International Relations Theory are Realism and Idealism. Each has their advocates, but it’s true that the Realists have dominated: the world’s a tough place, an anarchic system, and states maneuver to establish power and security, making coalitions, offshore balancing, etc.

I think we can put aside Idealism — though it has its advocates, including, curiously, one of the founders and leading figures of the modern tough-minded Realist school, Hans Morgenthau. In his 1960 work, The Purpose of American Politics, Morgenthau argued that the U.S., unlike other societies, has a “transcendent purpose”: establishing peace and freedom at home and indeed everywhere. A serious scholar, Morgenthau recognized that the historical record is radically inconsistent with the “transcendent purpose” of America, but he advised that we should not be misled by the apparent inconsistency. In his words, we should not “confound the abuse of reality with reality itself.” Reality is the unachieved “national purpose” revealed by “the evidence of history as our minds reflect it.” What actually happened is merely the “abuse of reality.” To confound abuse of reality with reality is akin to “the error of atheism, which denies the validity of religion on similar grounds.”

For the most part, however, realists adhere to Realism, without sentimentality. We might ask, however, how realistic Realism is. With a few exceptions — Kenneth Waltz for one — realists tend to ignore the roots of policy in the structure of domestic power, in which, of course, the corporate system is overwhelmingly dominant. This is not the place to review the matter, but I think it can be shown that much is lost by this stance. That’s true even of the core notion of Realism: security. True, states seek security, but for whom? For the general population? For the systems of power represented by the architects of policy? Such questions cannot be casually put aside.

The two existential crises we have discussed are a case in point. Does the government policy of maximization of the use of fossil fuels contribute to the security of the population? Or of ExxonMobil and its brethren. Does the current military posture of the U.S. — dismantling the INF Treatyinstead of negotiating disputes over violations, rushing ahead with hypersonic weapons instead of seeking to bar these insane weapons systems by treaty, and much else — contribute to the security of the population? Or to the component of the corporate manufacturing system in which the U.S. enjoys comparative advantage: destruction. Similar questions arise constantly.

What should replace the prevailing stance is government of, by and for the people, highlighting their concerns and needs.

The advent of globalization has been interpreted frequently enough in the recent past as leading to the erosion of the nation-state. Today, however, it is globalization that is being challenged, first and foremost by the resurgence of nationalism. Is there a case to be made in defense of globalization? And, by extension, is all nationalism bad and dangerous?

Globalization is neither good nor bad in itself. It depends how it is implemented. Enhancing opportunities for ideas, innovations, aesthetic contributions to disseminate freely is a welcome form of globalization, as well as opportunities for people to circulate freely. The WTO system, designed to set working people in competition with one another while protecting investor rights with an exorbitant patent regime and other devices, is a form of globalization that has many harmful consequences that would be avoided in authentic trade agreements designed along different lines — and it should be borne in mind that much of the substance of the “free trade agreements” is not about free trade or even trade in any meaningful sense.

Same with nationalism. In the hands of the Nazis, it was extremely dangerous. If it is a form of bonding and mutual support within some community it can be a valuable part of human life.

The current resurgence of nationalism is in large part a reaction to the harsh consequences of neoliberal globalization, with special features such as the erosion of democracy in Europe by transfer of decision-making to the unelected Troika with the northern banks looking over their shoulders. And it can and does take quite ugly forms — the worst, perhaps, the reaction to the so-called “refugee crisis” — more accurately termed a moral crisis of the West, as Pope Francis has indicated.

But none of this is inherent in globalization or nationalism.

In your critiques of U.S. foreign policy, you often refer to the United States as the world’s biggest terrorist state. Is there something unique about the United States as an imperial state? And is U.S. imperialism still alive and kicking?

The U.S. is unique in many respects. That includes the opening words of the Declaration of Independence, “We the People,” a revolutionary idea, however flawed in execution. It is also a rare country that has been at war almost without a break from its first moment. One of the motives for the American Revolution was to eliminate the barrier to expansion into “Indian country” imposed by the British. With that overcome, the new nation set forth on wars against the Indian nations that inhabited what became the national territory; wars of “extermination,” as the most prominent figures recognized, notably John Quincy Adams, the architect of Manifest Destiny. Meanwhile half of Mexico was conquered in what General U.S. Grant, later president, called one of the most “wicked wars” in history.

There is no need to review record of interventions, subversion and violence, particularly since World War II, which established the U.S. in a position of global dominance with no historical precedent. The record includes the worst crime of the postwar period, the assault on Indochina, and the worst crime of this millennium, the invasion of Iraq.

Like most terms of political discourse, “imperialism” is a contested notion. Whatever term we want to use, the U.S. is alone in having hundreds of military bases and troops operating over much of the world. It is also unique in its willingness and ability to impose brutal sanctions designed to punish the people of states designated as enemies. And its market power and dominance of the international financial system provide these sanctions with extraterritorial reach, compelling even powerful states to join in, however unwillingly.

The most dramatic case is Cuba, where U.S. sanctions are strongly opposed by the entire world, to no avail. The vote against these sanctions was 189-2, U.S. and Israel, in the latest UNGA [United Nations General Assembly] condemnation. The sanctions have been in place for almost 60 years, harshly punishing Cubans for what the State Department called “successful defiance” of the U.S. Trump’s sanctions on Venezuela have turned a humanitarian crisis into a catastrophe, according to the leading economist of the opposition, Francisco Rodriguez. His sanctions on Iran are quite explicitly designed to destroy the economy and punish the population.

This is no innovation. Clinton’s sanctions on Iraq (joined by Blair) were so destructive that each of the distinguished international diplomats who administered the “oil for food” program resigned in protest, charging that the sanctions were “genocidal.” The second, Hans-Christof von Sponeck, published a detailed and incisive book about the impact of the sanctions (A Different Kind of War). It has been under a virtual ban. Too revealing, perhaps.

The brutal sanctions punished the population and devastated the society, but strengthened the tyrant, compelling people to rely on his rationing system for survival, possibly saving him from overthrow from within, as happened to a string of similar figures. That’s quite standard. The same is reportedly true in Iran today.

It could be argued that the sanctions violate the Geneva Conventions, which condemn “collective punishment” as a war crime, but legalistic shenanigans can get around that.

The U.S. no longer has the capacity it once did to overthrow governments at will or to invade other countries, but it has ample means of coercion and domination, call it “imperialism” or not.

Why is the United States the only major country in the world displaying consistently an aversion to international human rights treaties, which include, among many others, the Convention on the Elimination of all Forms of Discrimination Against Women (CEDAW)?

The U.S. almost never ratifies international conventions, and in the few cases where it does, it is with reservations that exclude the U.S. That’s even true of the Genocide Convention, which the U.S. finally did ratify after many years, exempting itself. The issue arose in 1999, when Yugoslavia brought a charge of war crimes to the ICJ [International Court of Justice] against NATO. One of the charges was “genocide.” The U.S. therefore rejected World Court jurisdiction on the grounds that it was not subject to the Genocide Convention, and the Court agreed — agreeing, in effect, that the U.S. is entitled to carry out genocide with impunity.

It might be noted that the U.S. is currently alone (along with China and Taiwan) in rejecting a World Court decision, namely, the 1986 Court judgment ordering the U.S. to terminate its “unlawful use of force” against Nicaragua and to pay substantial reparations. Washington’s rejection of the Court decision was applauded by the liberal media on the grounds that the Court was a “hostile forum” (New York Times), so its decisions don’t matter. A few years earlier the Court had been a stern arbiter of Justice when it ruled in favor of the U.S. in a case against Iran.

The U.S. also has laws authorizing the executive to use force to “rescue” any American brought to the Hague — sometimes called in Europe “the Hague Invasion Act.” Recently it revoked the visa of the Chief Prosecutor of the ICC [International Criminal Court] for daring to consider inquiring into U.S. actions in Afghanistan. It goes on.

Why? It’s called “power,” and a population that tolerates it — and for the most part probably doesn’t even know about it.

Since the Nuremberg trials between 1945-49, the world has witnessed many war crimes and crimes against humanity that have gone unpunished, and interestingly enough, some of the big powers (U.S., China and Russia) have refused to support the International Criminal Court which, among others things, can prosecute individuals for war crimes. In that context, does the power to hold leaders responsible for unjust wars, crimes against humanity, and crimes of aggression hold promise in the international order of today?

That depends on whether states will accept jurisdiction. Sometimes they do. The NATO powers (except for the U.S.) accepted ICJ jurisdiction in the Yugoslavia case, for example — presumably because they took for granted that the Court would never accept the Yugoslavian pleas, even when they were valid, as in the case of the targeted destruction of a TV station, killing 16 journalists. In the more free and democratic states, populations could, in principle, decide that their governments should obey international law, but that is a matter of raising the level of civilization.

John Bolton and other ultranationalists, and many others, argue that the U.S. must not abandon its sovereignty to international institutions and international law. They are therefore arguing that U.S. leaders should violate the Constitution, which declares that valid treaties are the supreme law of the land. That includes in particular the UN Charter, the foundation of modern international law, established under U.S. auspices.

Climate change no issue with human population of, say, 10

I use the extreme example of 10 to cut to the chase, get to the point.

With a low human population, human-caused climate change would not be a concern.

With a low human population, neither would habitat loss or any other of the current threats to the diversity of life on Earth.

It wouldn’t matter if every person in a low human population was the most rapacious sort of capitalist. They couldn’t make a dent. It wouldn’t matter if every one was socialist, communist, racist, atheist, Buddhist, Confucionist, Taoist, Christian, Jew, or Muslim. What packs the most clout is the sheer mass of the human population

This mass is the great hulking monster behind the threats to climate and biodiversity. And yet the growth of the human population has important sources of support. For the political leaders yearning for military might, it means bigger armies. For organized religion(s), it means bigger congregations. For the business world, it means more customers — and a labor supply abundant enough to make labor cheap. Over all this hangs a silence amounting to a near-universal taboo.

Everything I know or think I know persuades me that continuing on our present course will, sooner or later, plausibly beginning in the lifetime of children born since 1980, create conditions that will set off a severe and sharp culling of the human herd. But we’ll be bringing a lot down with us as we go, and we are already seeing all the evidence we need of that.

++++___________________________________________________++++

“Research suggests that the scale of human population and the current pace of its growth contribute substantially to the loss of biological diversity. Although technological change and unequal consumption inextricably mingle with demographic impacts on the environment, the needs of all human beings—especially for food—imply that projected population growth will undermine protection of the natural world. 

“Numerous solutions have been proposed to boost food production while protecting biodiversity, but alone these proposals are unlikely to staunch biodiversity loss. An important approach to sustaining biodiversity and human well-being is through actions that can slow and eventually reverse population growth: investing in universal access to reproductive health services and contraceptive technologies, advancing women’s education, and achieving gender equality.”

One of the largest banks issued an alarming warning that Earth is running out of the resources to sustain life

  • The planet is running out of resources, HSBC warned in a new note.
  • Earth Overshoot Day — the point in a year at which our demand for natural resources exceeds what the planet can renew — occurred on August 1, just seven months into 2018.
  • HSBC said companies and governments are not “adequately prepared” for climate effects.

One of the world’s largest banks says the planet is running out of resources and warns that neither governments nor companies are prepared for climate change.

The world spent its entire natural resource budget for the year by August 1, a group of analysts at HSBC said in a note that cited research from the Global Footprint Network (GFN).

That means that the world’s citizens used up all the planet’s resources for the year in just seven months, according to GFN’s analysis.

“In our opinion, these findings and events show that many businesses and governments are not adequately prepared for climate impacts, nor are they using natural resources efficiently,” the HSBC analysts said in the note.

Many banks and asset managers have started factoring climate risks into their decision-making — a move spurred in part by former New York City Mayor Michael Bloomberg. But it’s far less common to see multinational banks sound the alarm about climate change so explicitly in their equity research.

To calculate Earth’s natural resource budget, GFN considers the demand for natural resources — which includes food, forests, and marine products — as well as humans’ effects on the environment from factors like carbon emissions. The combined total is designed give a comprehensive picture of humanity’s global footprint.

Earth Overshoot Day , the point in a year at which we use up a year’s worth of resources, has been steadily moving forward in time since GFN first started tracking it. In 1970, we “overshot” Earth’s resource budget by only 2 days — Overshoot Day fell on December 29, according to HSBC. That date has been pushed up by almost five months since then.

HSBC’s note also warned about extreme events resulting from heat, including the wildfires in Scandinavia and broken temperature records around the world.

“As scientists work on attribution analysis for specific events — the general consensus is that climate change is making these events more likely to occur and more severe,” HSBC said.

The predicted effects of climate change are starting to become real.Wildfires have torn through California in recent years, and they’re part of a worsening trend related to rising global temperatures. Other consequences include increased frequency of hurricanes and flooding, melting ice sheets , and greater numbers of heat waves .

Recent studies have shown that global temperatures by the year 2100 could be up to 15% higher than the highest projections from the Intergovernmental Panel on Climate Change.

According to HSBC, extreme events have severe economic and social costs.

“In our view, adaptation will move further up the agenda with a growing focus on the social consequences,” the analysts said.

Long-Lasting Civilization May Be a Pipe Dream

https://www.truthdig.com/articles/long-lived-civilization-may-be-a-pipe-dream/

Humanity’s cherished hope that we are building a long-lived civilisation may be nothing more than a pipe-dream. Human endeavour, two scientists argue, may carry within it the seeds of its own destruction.

The two astrophysicists have turned one of the great questions in science into a way of examining the down-to-earth consequences of global warming, the pollution of the oceans with indestructible polymers, and the wholesale destruction of species in the last 300 years.

They put an innocent question: if there had been an advanced technological and industrial civilisation on Earth several hundred million years ago, how could anyone know? What marks would have been left by a race of intelligent reptiles with motorised transport, housing estates, international trade and an arms race?

In what they call the Silurian hypothesis – a reference not to the geological period long before the first creatures crawled from the sea onto the empty continents, but to a 1970 episode of the British television serial Dr Who – they turn to the only testbed available to contemporary Earthlings: the evidence of the Anthropocene, the geologists’ name for a new era that could be considered to have commenced with the Industrial Revolution.

If some alien or distant-future civilisation set out to study the Earth’s geological record, what signs would humans have left in the strata?

And almost immediately, their study confronts a paradox. “The longer human civilisation lasts, the larger the signal one would expect in the record. However, the longer a civilisation lasts, the more sustainable its practices would need to have become in order to survive,” they write in the International Journal of Astrobiology.

But the more sustainable a society, the smaller the footprint its agriculture, manufacture or energy generation would have made, and the smaller the signal in the geological record.

So the researchers, Adam Frank from the University of Rochester, New York and Gavin Schmidt, director of the Nasa Goddard Institute for Space Studies, set out to calculate the future signature of long-vanished human society.

Signs of change

They conclude that the burning of fossil fuels has already changed the carbon cycle in a way that would be recognisable in records of carbon isotopes. Global warming – a consequence of that fossil fuel combustion – would be detectable in the rocks.

Global agriculture would be signalled by increases of erosion and sedimentation rates over time, and plastic pollutants would be detectable for perhaps billions of years. And all-out thermonuclear war – were it to happen – would leave behind some unusual radioactive isotopes.

“As an industrial civilisation, we’re driving changes in the isotopic abundances because we’re burning carbon,” said Professor Frank. “But burning fossil fuels may actually shut us down as a civilisation. What imprints would this or other kinds of industrial activity from a long-dead civilisation leave over tens of millions of years?”

The latest study is not the only one to contemplate the paradox of a self-destroying civilisation. Last year an Arkansas mathematician considered the silence of the extraterrestrials.

Nothing heard

For 40 years, humans have been listening for the noise of other intelligent civilisations in the galaxy, and have heard nothing. Maybe, he suggested in the same journal, modern humans are typical of technological civilisations, and destroy either their planet, or themselves, almost as soon as they exploit technology.

Perhaps, he suggests, a technological civilisation that lasted for millions of years would not be typical.

The latest study, in essence, pursues the same logic. Human advance for the moment is not sustainable. The people of the Anthropocene have already tipped 12 billion tonnes of indestructible plastics into landfills, and created a technosphere that totals about 30 trillion tonnes. And by 2050, humans will have built another 25 million km of roads.

“You want to have a nice, large-scale civilisation that does wonderful things but that doesn’t push the planet into domains that are dangerous for itself, the civilisation,” said Professor Frank. “We need to figure out a way of producing and using energy that doesn’t put us at risk.”

Near-term Human Extinction: Part II, Feedbacks 21-49

https://guymcpherson.com/climate-chaos/climate-change-summary-and-update/

21. Extreme weather events drive climate change, as reported in the 15 August 2013 issue of Nature (Nature, August 2013). Details are elucidated via modeling in the 6 June 2014 issue of Global Biogeochemical Cycles. Further data and explanation are presented in the 27 April 2015 online issue of Nature Climate Change.

Explaining Extreme Events of 2014 from a Climate Perspective” was published by the Bulletin of the American Meteorological Society in their December 2015 issue and draws on conclusions from 32 international teams of scientists who investigated 28 separate weather events. Findings of this report, released on 5 November 2015, include the following: “Human activities, such as greenhouse gas emissions and land use, influenced specific extreme weather and climate events in 2014, including tropical cyclones in the central Pacific, heavy rainfall in Europe, drought in East Africa, and stifling heat waves in Australia, Asia, and South America.”

According to a paper in the 13 June 2016 issue of the Proceedings of the National Academy of Sciences, atmospheric aerosols strengthen storm clouds, thus leading to extreme weather. An abundance of aerosol particles in the atmosphere — constantly added via industrial activity — can increase the lifespans of large storm clouds by delaying rainfall, making the clouds grow larger and live longer, and producing more extreme storms.

For many years, scientists have cautioned that individual weather events couldn’t be attributed to climate change. Now, however, specific extreme weather events can be attributed to climate change. A 200-page, March 2016 report from the National Academies of Science, Engineering, and Medicine examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.

22. Drought-induced mortality of trees contributes to increased decomposition of carbon dioxide into the atmosphere and decreased sequestration of atmospheric carbon dioxide. Such mortality has been documented throughout the world since at least November 2000 in Nature, with recent summaries in the February 2013 issue of Nature for the tropics, the August 2013 issue of Frontiers in Plant Science for temperate North America, and the 21 August 2015 issue of Science for boreal forests. The situation is exacerbated by pests and disease, as trees stressed by altered environmental conditions become increasingly susceptible to agents such as bark beetles and mistletoe (additional examples abound).

One extremely important example of this phenomenon is occurring in the Amazon, where drought in 2010 led to the release of more carbon than the United States that year (Science, February 2011). The calculation badly underestimates the carbon release. In addition, ongoing deforestation in the region is driving declines in precipitation at a rate much faster than long thought, as reported in the 19 July 2013 issue of Geophysical Research Letters. An overview of the phenomenon, focused on the Amazon, was provided by Climate News Network on 5 March 2014~. “The observed decline of the Amazon sink diverges markedly from the recent increase in terrestrial carbon uptake at the global scale, and is contrary to expectations based on models,” according to a paper in the 19 March 2015 issue of Nature. Finally, according to a paper in the 1 July 2016 issue of Global Biogeochemical Cycles, the 2010 drought completely shut down the Amazon Basin’s carbon sink, by killing trees and slowing their growth.

Tropical rain forests, long believed to represent the primary driver of atmospheric carbon dioxide, are on the verge of giving up that role. According to a 21 May 2014 paper published in Nature, “the higher turnover rates of carbon pools in semi-arid biomes are an increasingly important driver of global carbon cycle inter-annual variability,” indicating the emerging role of drylands in controlling environmental conditions. “Because of the deforestation of tropical rainforests in Brazil, significantly more carbon has been lost than was previously assumed.” In fact, “forest fragmentation results in up to a fifth more carbon dioxide being emitted by the vegetation.” These results come from the 7 October 2014 issue of Nature Communications. A paper in the 28 December 2015 online issue of the Proceedings of the National Academy of Sciences indicates Amazon forest could transition to savanna-like states in response to climate change. Savannas are simply described as grasslands with scattered trees or shrubs. The abstract of the paper suggests that, “in contrast to existing predictions of either stability or catastrophic biomass loss, the Amazon forest’s response to a drying regional climate is likely to be an immediate, graded, heterogeneous transition from high-biomass moist forests to transitional dry forests and woody savannah-like states.”

The boreal forest wraps around the globe at the top of the Northern Hemisphere. It is the planet’s single largest biome and makes up 30 percent of the globe’s forest cover. Moose are the largest ungulate in the boreal forest and their numbers have plummeted. The reason is unknown.

Dennis Murray, a professor of ecology at Trent University in Peterborough, Ontario, thinks the dying moose of Minnesota and New Hampshire and elsewhere are one symptom of something far bigger – a giant forest ecosystem that is rapidly shrinking, dying, and otherwise changing. “The boreal forest is breaking apart,” he says. “The question is what will replace it?”

Increasing drought threatens almost all forests in the United States, according to a paper in the 21 February 2016 online issue of Global Change Biology. According to the paper’s abstract, “diebacks, changes in composition and structure, and shifting range limits are widely observed.”

For the first time scientists have investigated the net balance of the three major greenhouse gases — carbon dioxide, methane, and nitrous oxide — for every region of Earth’s land masses. The results were published in the 10 March 2016 issue of Nature. The surprising result: Human-induced emissions of methane and nitrous oxide from ecosystems overwhelmingly surpass the ability of the land to soak up carbon dioxide emissions, which makes the terrestrial biosphere a contributor to climate change.

An abstract of a paper to be published in the April 2016 issue of Biogeochemistry includes these sentences: “Rising temperatures and nitrogen (N) deposition, both aspects of global environmental change, are proposed to alter soil organic matter (SOM) biogeochemistry. … Overall, this study shows that the decomposition and accumulation of molecularly distinct SOM components occurs with soil warming and N amendment and may subsequently alter soil biogeochemical cycling.” In other words, as global temperatures rise, the organic matter in forests appears to break down more quickly, thereby accelerating the release of carbon into the atmosphere.

23. Ocean acidification leads to release of less dimethyl sulphide (DMS) by plankton. DMS shields Earth from radiation. (Nature Climate Change, online 25 August 2013). Plankton form the base of the marine food web, some populations have declined 40% since 1950 (e.g., article in the 29 July 2010 issue of Nature), and they are on the verge of disappearing completelyaccording to a paper in the 18 October 2013 issue of Global Change Biology. As with carbon dioxide, ocean acidification is occurring rapidlyaccording to a paper in the 26 March 2014 issue of Global Biogeochemical Cycles. Acidification is proceeding at a pace unparalleled during the last 300 million years, according to research published in the 2 March 2012 issue of Science. Over the past 10 years, the Atlantic Ocean has soaked up 50 percent more carbon dioxide than it did the decade before, measurably speeding up the acidification of the ocean, according to a paper published in the 30 January 2016 issue of Global Biogeochemical Cycles. Not surprisingly, the degradation of the base of the marine food web is reducing the ability of fish populations to reproduce and replenish themselves across the globe, as reported in the 14 December 2015 online edition of the Proceedings of the National Academy of Sciences.

Diatoms, one of the major groups of plankton, is declining globally at the rate of about one percent per year, according to a paper in the 23 September 2015 issue of Global Biogeochemical Cycles.

The Southern Ocean is acidifying at such a rate because of rising carbon dioxide emissions that large regions may be inhospitable for key organisms in the food chain to survive as soon as 2030, according to a paper in the 2 November 2015 online issue of Nature Climate Change.

A paper in the 26 November 2015 issue of Science Express indicates millennial-scale shifts in plankton in the subtropical North Pacific Ocean that are “unprecedented in the last millennium.” The ongoing shift “began in the industrial era and is supported by increasing N2-fixing cyanobacterial production. This picoplankton community shift may provide a negative feedback to rising atmospheric CO2.” One of the authors of the papers is quoted during an interview: “This picoplankton community shift may have provided a negative feedback to rising atmospheric carbon dioxide, during the last 100 years. However, we cannot expect this to be the case in the future.”

Further research on primary productivity in the ocean was published in paper in the 19 January 2016 issue of Geophysical Research Letters. Referring to the Indian Ocean, the abstract concludes, “future climate projections suggest that the Indian Ocean will continue to warm, driving this productive region into an ecological desert.”

For the first time, researchers have documented algae-related toxins in Arctic sea mammals. Specifically, toxins produced by harmful algal blooms are showing up in Alaska marine mammals as far north as the Arctic Ocean — much farther north than ever reported previously, according to a paper in the 11 February 2016 issue of Harmful Algae. The abstract indicates, “In this study, 905 marine mammals from 13 species were sampled including; humpback whales, bowhead whales, beluga whales, harbor porpoises, northern fur seals, Steller sea lions, harbor seals, ringed seals, bearded seals, spotted seals, ribbon seals, Pacific walruses, and northern sea otters. Domoic acid was detected in all 13 species examined and had the greatest prevalence in bowhead whales (68%) and harbor seals (67%). Saxitoxin was detected in 10 of the 13 species … These results provide evidence that … toxins are present throughout Alaska waters at levels high enough to be detected in marine mammals and have the potential to impact marine mammal health in the Arctic marine environment.”

24. Jellyfish have assumed a primary role in the oceans of the world (26 September 2013 issue of the New York Times Review of Books, in a review of Lisa-ann Gershwin’s book, Stung! On Jellyfish Blooms and the Future of the Ocean): “We are creating a world more like the late Precambrian than the late 1800s — a world where jellyfish ruled the seas and organisms with shells didn’t exist. We are creating a world where we humans may soon be unable to survive, or want to.” Jellyfish contribute to climate change via (1) release of carbon-rich feces and mucus used by bacteria for respiration, thereby converting bacteria into carbon dioxide factories and (2) consumption of vast numbers of copepods and other plankton.

25. Sea-level rise causes slope collapse, tsunamis, and release of methane, as reported in the September 2013 issue of GeologyIn eastern Siberia, the speed of coastal erosion has nearly doubled during the last four decades as the permafrost melts. And it appears sea-level rise has gone exponential, judging from Scribbler’s 4 May 2015 analysis. Considering only data through 2005, according to a paper published 28 September 2015 in the Proceedings of the National Academy of Sciences, the 500-year return time of floods in New York City has been reduced to 24.4 years.

26. Rising ocean temperatures will upset natural cycles of carbon dioxide, nitrogen and phosphorus, hence reducing plankton (Nature Climate Change, September 2013). Ocean warming has been profoundly underestimated since the 1970s according to a paper published in the online version of Nature Climate Change on 5 October 2014. Specifically, the upper 2,300 feet of the Southern Hemisphere’s oceans may have warmed twice as quickly after 1970 than had previously been thought. According to a 22 January 2015 article in The Guardian, “the oceans are warming so fast, they keep breaking scientists’ charts.”

Another indication of a warming ocean is coral bleaching. The third global coral bleaching event since 1998, and also the third in evidence, ever, is underway on Australia’s Great Barrier Reef. According to Australia National News on 28 March 2016, a survey of the Great Barrier Reef reports 95% of the northern reefs were rated as severely bleached, and only 4 of 520 reefs surveyed were found to be unaffected by bleaching.

27. Earthquakes trigger methane release, and consequent warming of the planet triggers earthquakes, as reported by Sam Carana at the Arctic Methane Emergency Group (October 2013)

28. Small ponds in the Canadian Arctic are releasing far more methane than expected based on their aerial cover (PLoS ONE, November 2013). This is the first of several freshwater ecosystems releasing methane into the atmosphere, as reviewed in the 19 March 2014 issue of Nature and subsequently described by a large-scale study in the 28 April 2014 issue of Global Change Biology. Release of methane from these sources in the Arctic and Greenland, according to the 20 May 2012 issue of Nature Geoscience, “imply that in a warming climate, disintegration of permafrost, glaciers and parts of the polar ice sheets could facilitate the transient expulsion of 14C-depleted methane trapped by the cryosphere cap.”

The mechanism underlying methane release in these systems is poorly understood. If sunlight drives the process, as suggested by a paper in the 22 August 2014 issue of Science, then amplification is expected over time as ponds and lakes are increasingly exposed.

Water bodies within Africa’s interior are adding significantly to the overall release of greenhouse gases into the atmosphere, according to a paper in the 20 July 2015 online edition of Nature Geoscience. Specifically, “total carbon dioxide-equivalent greenhouse-gas emissions [are] … about 0.9 Pg carbon per year, equivalent to about one quarter of the global ocean and terrestrial combined carbon sink.”

Large water bodies beneath deserts could profoundly worsen the situation. According to a paper published in the 28 July 2015 issue of Geophysical Research Letters, a large carbon sink or pool lies beneath the Tarim basin in Xinjiang, China. The hidden pool of water stores “more carbon than all the plants on the planet put together. While more water may sound like a good thing, researchers believe that if this carbon were to escape into the atmosphere, we would be in serious, serious trouble.” Specifically, the senior authored explained in an interview: “It’s like a can of coke. If it is opened all the greenhouse gas will escape into the atmosphere.”

A paper in the 29 October 2015 issue of Limnology and Oceanography also addresses the issue of methane release from lakes. A write-up for the general public titled, “Global Warming Will Progress Much More Quickly Than Expected, Study Predicts” includes this line: “The findings suggest we have a ‘vicious circle’ ahead of us in which the burning of fossil fuels leads to higher temperatures, which in turn trigger higher levels of methane release and further warming.” This is a fine explanation for a self-reinforcing feedback loop.

A study published in the 17 November 2015 edition of Nature Geoscience shows that lakes in the northern hemisphere will probably release much more carbon dioxide due to global climate changes. The investigation, based on data from more than 5,000 Swedish lakes, demonstrates that carbon dioxide emissions from the world’s lakes, water courses, and reservoirs are equivalent to almost a quarter of all the carbon dioxide produced by burning fossil fuels.

Citing two recent journal articles, a paper in the 19 November 2015 issue of Yale Environment 360 concludes, “the world’s iconic northern lakes are undergoing major changes that include swiftly warming waters, diminished ice cover, and outbreaks of harmful algae.” The lakes include Lake Baikal, “the deepest, largest in volume, and most ancient freshwater lake in the world, holding one-fifth of the planet’s above-ground drinking supply. It’s a Noah’s Ark of biodiversity, home to myriad species found nowhere else on earth.”

Further support for the importance of streams and rivers as sources of atmospheric methane comes from a paper published in the November 2015 issue of Ecological Monographs~. The headline of the write-up for the general public tells the story: “Greenhouse gas emissions from freshwater higher than thought.”

paper in the 23 November 2015 issue of Journal of Geophysical Research: Biogeosciencesfound, according to the abstract: “A sediment upwelling at the end of the thaw season likely contributed to these [methane] emissions. We suggest that, unlike wetlands, shallow seasonally ice-covered lakes can have their highest methane emission potential in the cold season, likely dominating the spring methane release of subarctic landscapes with high lake coverage.” In other words, as with methane release from the Arctic Ocean, methane release is abundant during the cold season. According to a paper in the 16 June 2016 online issue of Geophysical Research Letters, “Our findings indicate that permafrost below shallow lakes has already begun crossing a critical thawing threshold approximately 70 years prior to predicted terrestrial permafrost thaw in northern Alaska.”

As reported in the 16 December 2015 issue of Geophysical Research Letters: “In this first worldwide synthesis of in situ and satellite-derived lake data, we find that lake summer surface water temperatures rose rapidly (global mean = 0.34°C decade−1) between 1985 and 2009.”

paper in the 4 January 2016 online edition of Nature Geoscience finds, “lakes and ponds are a dominant methane source at high northern latitudes.” “By compiling previously reported measurements made at a total of 700 northern water bodies the researchers have been able to more accurately estimate emissions over large scales. They found that methane emissions from lakes and ponds alone are equivalent to roughly two-thirds of all natural methane sources in the northern region.

According to a paper in the 1 February 2016 issue of Nature Geoscience, ponds less than a quarter of an acre in size make up only 8.6% of the surface area of the world’s lakes and ponds, yet they account for 15.1% of carbon dioxide emissions and 40.6% of diffusive methane emissions.

29. Mixing of the jet stream is a catalyst, too. High methane releases follow fracturing of the jet stream, accounting for a previous rise in regional temperature up to 16 C in less than 20 years (Paul Beckwith via video on 19 December 2013).

30. Research indicates that “fewer clouds form as the planet warms, meaning less sunlight is reflected back into space, driving temperatures up further still” (Nature, January 2014)

31. “Thawing permafrost promotes microbial degradation of cryo-sequestered and new carbon leading to the biogenic production of methane” (Nature Communications, February 2014). According to a paper in the 21 October 2015 issue of the Proceedings of the National Academy of Sciences,: “The observed DOC [dissolved organic carbon] loss rates are among the highest reported for permafrost carbon and demonstrate the potential importance of LMW [low–molecular-weight] DOC in driving the rapid metabolism of Pleistocene-age permafrost carbon upon thaw and the outgassing of CO2 to the atmosphere by soils and nearby inland waters.”

32. Over the tropical West Pacific there is a natural, invisible hole extending over several thousand kilometers in a layer that prevents transport of most of the natural and man-made substances into the stratosphere by virtue of its chemical composition. Like in a giant elevator, many chemical compounds emitted at the ground pass thus unfiltered through this so-called “detergent layer” of the atmosphere.Global methane emissions from wetlands are currently about 165 teragrams (megatons metric) each year. This research estimates that annual emissions from these sources will increase by between 17 and 260 megatons annually. By comparison, the total annual methane emission from all sources (including the human addition) is about 600 megatons each year. (Nature Geoscience, February 2014)

33. “Volcanologist Bill McGuire describes how rapid melting of glaciers and ice sheets as a result of climate change could trigger volcanoes, earthquakes, and tsunamis” (13 February 2014 issue of The Guardian. According to a paper published online in the 5 February 2015 issue of Geophysical Research Letters, “underwater volcanoes defy expectations and erupt in bursts rather than a slow pace.

34. Deep ocean currents apparently are slowing. According to one of the authors of the paper, “we’re likely going to see less uptake of human produced, or anthropogenic, heat and carbon dioxide by the ocean, making this a positive feedback loop for climate change.” Because this phenomenon contributed to cooling and sinking of the Weddell polynya: “it’s always possible that the giant polynya will manage to reappear in the next century. If it does, it will release decades-worth of heat and carbon from the deep ocean to the atmosphere in a pulse of warming.” (Nature Climate Change, February 2014; model results indicate “large spatial redistribution of ocean carbon,” as reported in the March 2014 issue of the Journal of Climate)

35. Increased atmospheric carbon dioxide causes soil microbes to produce more carbon dioxide (Science, 2 May 2014)

36. Reductions in seasonal ice cover in the Arctic “result in larger waves, which in turn provide a mechanism to break up sea ice and accelerate ice retreat” (Geophysical Research Letters, 5 May 2014). Further corroboration is found in the 27 March 2015 issue of Geophysical Research Letters.

37. A huge hidden network of frozen methane and methane gas, along with dozens of spectacular flares firing up from the seabed, has been detected off the North Island of New Zealand (preliminary results reported in the 12 May 2014 issue of the New Zealand Herald). The first evidence of widespread active methane seepage in the Southern Ocean, off the sub-Antarctic island of South Georgia, was subsequently reported in the 1 October 2014 issue of Earth and Planetary Science Letters.

38. As reported in the 8 June 2014 issue of Nature Geosciencerising global temperatures could increase the amount of carbon dioxide naturally released by the world’s oceans, fueling further climate change

39. As global-average temperature increases, “the concentrations of water vapor in the troposphere will also increase in response to that warming. This moistening of the atmosphere, in turn, absorbs more heat and further raises the Earth’s temperature.” As reported in the paper’s abstract: “Our analysis demonstrates that the upper-tropospheric moistening observed over the period 1979–2005 cannot be explained by natural causes and results principally from an anthropogenic warming of the climate. By attributing the observed increase directly to human activities, this study verifies the presence of the largest known feedback mechanism for amplifying anthropogenic climate change.” (Proceedings of the National Academy of Sciences, 12 August 2014According to a July 2015 report in Skeptical Science, “water vapor feedback roughly doubles the amount of warming caused by CO2. So if there is a 1°C change caused by CO2, the water vapor will cause the temperature to go up another 1°C. When other feedback loops are included, the total warming from a potential 1°C change caused by CO2 is, in reality, as much as 3°C.

40. Soil microbial communities release unexpectedly more carbon dioxide when temperatures rise (Nature, 4 September 2014). As a result, “substantial carbon stores in Arctic and boreal soils could be more vulnerable to climate warming than currently predicted.”

41. “During the last glacial termination, the upwelling strength of the southern polar limb of the Atlantic Meridional Overturning Circulation varied, changing the ventilation and stratification of the high-latitude Southern Ocean. During the same period, at least two phases of abrupt global sea-level rise—meltwater pulses—took place.” In other words, when the ocean around Antarctica became more stratified, or layered, warm water at depth melted the ice sheet faster than when the ocean was less stratified. (Nature Communications, 29 September 2014) Robert Scribbler refers to AMOC as “the heartbeat of the world ocean system.” As reported in the 23 March 2015 online issue of Climatic Change, the slowing of the AMOC is “exceptional” and is tied to melting ice in Greenland. This twentieth-century slowdown apparently is unique, at least within the last thousand years.

42. “Open oceans are much less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum. This means that the Arctic Ocean traps much of the energy in far-infrared radiation, a previously unknown phenomenon that is likely contributing to the warming of the polar climate.” (Proceedings of the National Academy of Sciences, November 2014)

43. Dark snow is no longer restricted to Greenland. Rather, it’s come to much of the northern hemisphere, as reported in the 25 November 2014 issue of the Journal of Geophysical Research. Eric Holthaus’s description of this phenomenon in the 13 January 2015 edition of Slate includes a quote from one of the scientists involved in the research project: “The climate models need to be adding in a process they don’t currently have, because that stuff in the atmosphere is having a big climate effect.” In other words, as with the other major self-reinforcing feedback loops, dark snow is not included in contemporary models.

44. The “representation of stratospheric ozone in climate models can have a first-order impact on estimates of effective climate sensitivity.” (Nature Climate Change, December 2014)

45. “While scientists believe that global warming will release methane from gas hydrates worldwide, most of the current focus has been on deposits in the Arctic. This paper estimates that from 1970 to 2013, some 4 million metric tons of methane has been released from hydrate decomposition off Washington [state]. That’s an amount each year equal to the methane from natural gas released in the 2010 Deepwater Horizon blowout off the coast of Louisiana, and 500 times the rate at which methane is naturally released from the seafloor.” (Geophysical Research Letters, online version 5 December 2014)

46. “An increase in human-made carbon dioxide in the atmosphere could initiate a chain reaction between plants and microorganisms that would unsettle one of the largest carbon reservoirs on the planet — soil” (Nature Climate Change, December 2014 )

47. Increased temperature of the ocean contributes to reduced storage of carbon dioxide. “Results suggest that predicted future increases in ocean temperature will result in reduced CO2 storage by the oceans” (Proceedings of the National Academy of Sciences, January 2015)

48. According to a paper in the 19 January 2015 issue of Nature Geoscience, melting glaciers contribute substantial carbon to the atmosphere, with “approximately 13% of the annual flux of glacier dissolved organic carbon is a result of glacier mass loss. These losses are expected to accelerate.”

49. According to a paper in the 20 April 2015 online issue of Nature Geoscience, ocean currents disturb methane-eating bacteria. “We were able to show that strength and variability of ocean currents control the prevalence of methanotrophic bacteria”, says Lea Steinle from University of Basel and the lead author of the study, “therefore, large bacteria populations cannot develop in a strong current, which consequently leads to less methane consumption.”
