Melting Arctic Ice is Changing Whale Migration. How One Choice We Make Every Day Can Help

It seems that every day brings a new discovery regarding the impacts of climate change on our planet. From its contribution to the Sixth Mass Extinction to its threat to coral reefs worldwide, to its impact on animal migration patterns, the negative effects of a changing climate are being seen everywhere.

Not even the farthest reaches of the globe can escape climate change or the damage it brings with it. The melting of sea ice around the Arctic Circle may not exactly be news, but we are only now starting to understand just how destructive these changes can be to wildlife.

As ice disappears in the Arctic Circle, a passage is opening up where marine animals can move between the Pacific and Atlantic Oceans. The warming Arctic Ocean is also inviting new species to the area. The full impacts of this phenomena may yet to be seen, but the prognosis is not exactly a good one.

A New Passage in The North

The Northwest Passage is a pathway through the Arctic Ocean, north of Canada, that passes between the Atlantic and Pacific Oceans. Historically, it has been appealing to shippers and explorers as navigating the icy water could offer an alternate route around North America. However, given the strong presence of dangerous sea ice, the Northwest Passage has rarely been navigated. That is, until recent years.

Since the 1970s, Arctic sea ice has declined by 14 percent. And while the year 2012 set the most recent record summer low of sea ice levels in the Arctic, the region has been on an overall downward trend. November 2015 has shown a growth in sea ice. However, this is expected given the returned winter. The National Snow and Ice Data Center still reports that November 2015 data shows a rate of decline of sea ice at 4.7 percent per decade.

With the opportunity of ice-free sailing in this swath of the Arctic Ocean, shippers are finding benefit in the unfortunate loss of our frozen habitat. And even a yacht race in the once frozen ocean has been proposed for 2017 based on the assumption the region will be hazard-free enough for the event. (Whaaaat?!)

Human activity around the Arctic Ocean is certainly changing along with the terrain, so it’s no wonder the animals in the region are also changing how they interact with their new environment.

Whales On the Move

The impact of climate change on Arctic sea ice has been pretty well documented over the last few years. The rising concern for loss of habitat for animals like polar bears and walruses has made the daily news on occasion, but these aren’t the only animals that are having their habitat changed under warming skies.

As the ice in the Northwestern Passage melts during the warmer months of the year in the northern hemisphere, the Passage is opening up. While an open sea lane free of thick ice may be appealing to shippers, marine mammals are also taking to exploring and utilizing the brand new path of ocean.

Take the gray whale, for instance. These animals went extinct in the Atlantic Ocean and were gone from sight 300- 400 years ago. Yet, in 2010, scientists documented a gray whale in the Mediterranean Ocean! A study released in the Marine Biodiversity Records the following year acknowledges that the chance that such an animal could go unnoticed by researchers for hundreds of years is pretty unlikely, and this animal most likely used the melting Northwest Passage to make its journey from the Pacific. Will more gray whales make this journey in the future? Will they reestablish a population of gray whales in the Atlantic Ocean?

Gray whales aren’t the only species of whale to show peculiar behavior changes as the result of melting Arctic sea ice. The altered habitat is inviting new visitors that compete with the Arctic’s year-round residents.

Bowhead whales make their home in the Arctic Circle all year. Not only would heavier ship traffic in the area be of concern, but new competition is also a worry as the sea ice in their homes melts away. Humpback and fin whales which tend to hang around the Arctic mainly in the summer may choose to stay longer, competing with bowhead whales for food.

The largest member of the dolphin family and a formidable threat to even large whales has been documented over recent years with increasingly frequent sightings in the cold waters of the Arctic. With the assistance of Inuit hunters in the area, scientists can confirm that killer whales are now appearing in the warming Arctic in numbers not ever seen before. Whereas their towering dorsal fin once made their navigation of icy waters difficult, the melting sea ice is now open territory for the animals to hunt. These charismatic black and white animals can now more easily prey on animals like bowhead whales, narwhals, and belugas in their new Arctic habitats.

The Take-Home Message

The fact that climate change is altering the habitats of animals not just in the Arctic, but all over the world is reason to be concerned. It’s also reason to take action!

Knowing what we do about the impact of climate change, it can be easy to feel defenseless or that this is a problem too large for us to even make a dent in. This, however, is hardly the case. While the carbon emissions of large industries like coal and oil need to be regulated, as an individual you have an incredible opportunity to start reducing your own carbon footprint. People are making small changes every day like choosing to walk or bike to work rather than driving, seeking out recycling bins for plastic waste, and even being mindful of the impact of their consumption choices. In keeping with this theme of doing small things, there is another solution that can have an enormously positive impact for the planet – and, it might just be the simplest one yet: changing the way you eat.

We all have the chance to lower our personal carbon footprints every time we sit down for a meal. By opting to eat fewer meat and dairy products in favor of plant-based alternatives, you can literally halve your own carbon footprint. How? Well, one of the largest drivers of greenhouse gas emissions is animal agriculture. The United Nations Food and Agriculture Organization (FAO) estimates that livestock production is responsible for 14.5 percent of global greenhouse gas emissions, while other organizations like the Worldwatch Institute have estimated it could be as much as 51 percent.

As the leading organization at the forefront of the conscious consumerism movement, it is One Green Planet’s view that our food choices have the power to heal our broken food system, give species a fighting chance for survival, and pave the way for a truly sustainable future.

Seaweed found to stop methane emissions from cattle rumen

By Thomas Hubert on 17 July 2017
  • Further research must now confirm in vitro findings in live animals.
    Further research must now confirm in vitro findings in live animals.

Successive in vitro studies have shown up to 100% reduction in the emissions of the potent greenhouse gas from grass digestion.

new study by Australian-based researchers shows that adding freeze-dried Asparagopsis taxiformis to test tubes replicating the fermentation process at work in a ruminant’s gut “completely inhibited the production of CH4” (methane).

The study led by James Cook University academic Matthew Vucko looked into various post-harvest treatments of the tropical red algae and found that “frozen and subsequently freeze-dried was the most effective processing method to maintain antimethanogenic activity”. It links the methane-inhibiting effect of the seaweed to the presence of the chemical compound bromoform.

Seaweed not only helped improve the cows’ health and growth, but also reduced their methane production

It builds upon research published last year, in which scientists added various types of seaweed to the fluid extracted from cattle’s rumen and observed gas emissions from the digestion of Rhodes grass. At the time, they found that adding 2% of asparagopsis taxiformis to the organic matter fed into the digestion process reduced methane emissions by at least 70% and up to 99%.

The latest study refined earlier findings to identify the treatment of seaweed most efficient at stopping methane formation.

According to Michael Battaglia of the Australian-based Commonwealth Scientific and Industrial Research Organisation, which supports the research, investigations started after a Canadian farmer noted the benefits of cattle grazing seaweed in 2005.

“Canadian researchers Rob Kinley and Alan Fredeen have since found that seaweed not only helped improve the cows’ health and growth, but also reduced their methane production by about 20%,” Battaglia wrote.

Climate change targets

The findings made since then are promising as agriculture represents one third of Ireland’s greenhouse gas emissions, most of these under the form of methane from ruminants. EU targetsimpose cuts on these emissions to combat climate change.

Further research is needed to confirm the potential of seaweed in controlling methane emissions from live animals as opposed to laboratory apparatus.

Side effects may be an issue as bromoform “is toxic to aquatic life with long lasting effects, is harmful if swallowed, causes serious eye irritation and causes skin irritation,” according to the European Chemicals Agency. The US National Library of Medicine adds that “chronic (long-term) animal studies indicate effects on the liver, kidney, and central nervous system (CNS) from oral exposure to bromoform,” which is also a “probable human carcinogen”.

Extreme Heat Waves Will Change How We Live. We’re Not Ready

From: TIME

Jun 23, 2017

Extreme heat struck across the Southwest U.S. this week, sending temperatures in Phoenix soaring to near 120°F and grounding airplanes that were unable to operate in such warm weather.

Heat waves are nothing new, but they have increased in frequency and severity in recent decades as a result of climate change. And each extreme heat event reveals another way our society simply isn’t built for such high temperatures, from our transport systems to the agriculture industry.

“We’ve built entire infrastructures with particular temperatures in mind,” says Matthew T. Huber, an associate professor of geography at Syracuse University. “When temperatures get really high, we don’t have the material capacity to deal with that.”

Still, humans continue to relocate to warm places like the Southwest, drawn by the temperate climate. In the coming decades, many climate researchers expect that pattern to reverse, as those once-desirable locations become too hot, flooded or otherwise uninhabitable. In some locations, particularly in the West, people will soon need to decide whether to rebuild for the new reality — or relocate elsewhere.

“There seems to have been a tendency for people to move to warmer locations with warm pleasant conditions,” says Jeremy Pal, a professor of civil engineering and environmental science at Loyola Marymount University. “If heatwaves become more frequent and/or severe or temperatures and humidity conditions become too extreme for an extended part of the year, I would expect populations to move to locations with less severe conditions.”

Here are four big ways we’re affected by extreme heat:

Transportation

Humans have constructed essentially every element of the modern transportation sector to operate under certain temperature conditions. Airplanes — like those in Phoenix — cannot safely take off under extreme heat conditions that affect how the engine operates. Amtrak monitors temperatures closely and reduces the speed of trains when it gets too hot. Roads and highways can buckle as concrete expands.

These problems are not necessarily unsolvable. Take the issue of airplanes, for instance. Aviation companies can build planes to withstand higher temperatures, and airports can extend runways to address engine issues. But all those changes would be costly and require a wholesale rethinking of many aspects of the industry.

Trump pulls US out of Paris deal: What it would mean

Pulling the United States out of the Paris climate deal would have unforeseen consequences for President Trump, his international agenda and U.S. climate policy.

It would leave the world’s superpower outside an accord meant to reduce greenhouse gas emissions that includes nearly every other country in the world, aside from Syria and Nicaragua.

While it is not entirely clear that Trump has made up his mind to end U.S. participation in the deal, sources say that at a minimum, he is leaning in that direction.Here’s how to interpret and understand the decision.

Trump is playing to the base

Trump has called the pact a “bad deal” for the United States, and made withdrawing from it a key component of his “America First” campaign platform.

At an April rally, he called the agreement “one-sided,” and said “the United States pays billions of dollars while China, Russia and India have contributed and will contribute nothing.”

Given his past statements and promises, it isn’t hard to see why Trump would want to pull the United States out of the deal.

Yet the decision has provoked a furious internal battle within the White House, pitting Trump’s family members Ivanka Trump and Jared Kushner against adviser Steve Bannon and EPA administrator Steve Pruitt.

Pulling the United States out of the deal means Trump is siding with Bannon and his base over the objections of centrists in his government — and the business community.

Exxon Mobil Corp. and many large American businesses urged Trump to stay in the deal, arguing it would maintain U.S. influence over future talks.

“By remaining a party to the Pars agreement, the United States will maintain a seat at the negotiating table to ensure a level playing field so that all energy sources and technologies are treated equitably in an open, transparent and competitive global market,”

Exxon CEO Darren Woods wrote in a May 9 letter to Trump.

By pulling out of the Paris accord, Trump would be signaling he’s willing to take on supporters of the deal who are usually his allies — in order to back his core base of supporters.

Many Republicans on Capitol Hill are likely to support pulling out of Paris — 20 leading Senate Republicans, including Majority Leader Mitch McConnell (R-Ky.) asked Trump to do just that last week.

Withdrawing from Paris would greatly please conservative groups, who have orchestrated an all-out push in opposition to the pact.

On climate change: ‘Do something, do anything, just don’t do nothing’

http://www.hcn.org/articles/a-lesson-of-hope-for-climate-action?utm_source=wcn1&utm_medium=email


My first thought, on entering the hall, was, “Wow, she doesn’t look like an endowed-chair environmental law professor.” This was back in the fall of 2006, when I went to hear Mary Christina Wood speak. She was about my age, with long chestnut hair, a warm expression, and no makeup. I’ve since marveled that I was even there that night. I live in a college town, and good talks are not unusual. But I had a young daughter at the time, and this may have been the only evening lecture I attended that entire year.

Wood, also the mother of young children, was eloquent. She understood in a way I was just starting to grasp that climate change, if left unchecked, would soon threaten the health, safety and life support systems of our own kids, as well as that of future generations and everything else in the natural world. I left the lecture hall deeply shaken.

“Climate change, if left unchecked, would soon threaten the health, safety and life support systems of our own kids.”

Three things I remember clearly: First, I was impressed with her moral clarity. Second, in an answer to a question about what to do about the approaching climate crisis, she said, “Do something, do anything, just don’t do nothing.” And third, I remember that I lay awake that night, fearing for my daughter’s future.

In an effort to compel the government to protect the climate on behalf of present and future generations, Wood was developing a legal theory based on the “public trust doctrine.” I had heard of this doctrine when I worked on water issues in national parks. But I don’t believe anyone had tried to apply it to the earth’s atmosphere before.

The basic idea is that the government has a responsibility to protect vital natural resources for the benefit of all. By allowing polluters to destroy a stable climate, the government is failing to do its duty, and the courts can compel the government to act. It seemed like an elegant argument.

At that moment, I was contemplating a career change, from conservation biologist to environmental writer. I contacted Wood, interviewed her and wrote one of my first stories, “Climate Revolutionary: Creating a legal framework for saving our planet,” which was published in High Country News on May 12, 2008. I have no doubt that encountering Mary Wood helped inspire me to become a climate writer and, in time, a climate activist.

Meanwhile, Wood wrote a book, Nature’s Trust: Environmental Law for a New Ecological Age, developing her legal theory. Her work provides the theoretical foundation for the global litigation approach advanced by an organization called “Our Children’s Trust.” It works with youth across the country and around the world to bring legal action to compel governments to reduce greenhouse gas pollution and stabilize the climate system.

Just two days after this year’s election, a group of 21 young Americans won the right in federal court in Eugene, Oregon, to sue the fossil-fuel industry and the U.S. government based on Wood’s approach. According to U.S. District Judge Ann Aiken, these young people have the right to seek the protection of the climate on behalf of all youth and future generations. Similar lawsuits are being brought in other states and countries as well.

As for me, one thing led to another. Replaying Wood’s words, “Do something, do anything, just don’t do nothing,” started a shift in my heart and my head. I began learning and writing more about climate change. In time, this led me to writing a book about responding to climate change and becoming a volunteer climate activist. Today, I spend a large portion of my time lobbying for a carbon fee and dividend law to reduce greenhouse gas emissions.

So this is a story about how a lucky meeting changed my life. It is also a story about how one woman — an extraordinary environmental law professor — has influenced the world. This doesn’t take into account all the other ways she may have changed lives. So this is really a lesson about hope.

The only lesson I learned from Donald Trump’s election is that we cannot ever know the future. All the professional pundits predicted he would lose, and many of us believed them. I think I finally understand that there is absolutely no way to know what will happen tomorrow or next week or next year.

But it is possible to look back and see the small choices that mattered, to realize you never know where they may lead. So my advice is to do something, do anything, just don’t do nothing. This is the only way to plant seeds that might — just might — grow into progress toward a world in which our children can survive and thrive.

Great Barrier Reef at ‘terminal stage’: scientists despair at latest coral bleaching data

https://www.theguardian.com/environment/2017/apr/10/great-barrier-reef-terminal-stage-australia-scientists-despair-latest-coral-bleaching-data?
Last year was bad enough, this is a disaster,’ says one expert as Australia Research Council finds fresh damage across 8,000km

Back-to-back severe bleaching events have affected two-thirds of Australia’s Great Barrier Reef, new aerial surveys have found.

The findings have caused alarm among scientists, who say the proximity of the 2016 and 2017 bleaching events is unprecedented for the reef, and will give damaged coral little chance to recover.

Scientists with the Australian Research Council’s Centre of Excellence for CoralReef Studies last week completed aerial surveys of the world’s largest living structure, scoring bleaching at 800 individual coral reefs across 8,000km.

The results show the two consecutive mass bleaching events have affected a 1,500km stretch, leaving only the reef’s southern third unscathed.

Where last year’s bleaching was concentrated in the reef’s northern third, the 2017 event spread further south, and was most intense in the middle section of the Great Barrier Reef. This year’s mass bleaching, second in severity only to 2016, has occurred even in the absence of an El Niño event.

https://interactive.guim.co.uk/embed/aus/2017/apr/gbr-bleaching/bleach-16-17/

Mass bleaching – a phenomenon caused by global warming-induced rises to sea surface temperatures – has occurred on the reef four times in recorded history.

Prof Terry Hughes, who led the surveys, said the length of time coral needed to recover – about 10 years for fast-growing types – raised serious concerns about the increasing frequency of mass bleaching events.

“The significance of bleaching this year is that it’s back to back, so there’s been zero time for recovery,” Hughes told the Guardian. “It’s too early yet to tell what the full death toll will be from this year’s bleaching, but clearly it will extend 500km south of last year’s bleaching.”

Last year, in the worst-affected areas to the reef’s north, roughly two-thirds of shallow-water corals were lost.

Hughes has warned Australia now faces a closing window to save the reef by taking decisive action on climate change.

The 2017 bleaching is likely to be compounded by other stresses on the reef, including the destructive crown-of-thorns starfish and poor water quality. The category-four tropical cyclone Debbie came too late and too far south for its cooling effect to alleviate bleaching.

https://interactive.guim.co.uk/embed/aus/2017/apr/gbr-bleaching/gbr-coverage

But Hughes said its slow movement across the reef was likely to have caused destruction to coral along a path up to 100km wide. “It added to the woes of the bleaching. It came too late to stop the bleaching, and it came to the wrong place,” he said.

The University of Technology Sydney’s lead reef researcher, marine biologist David Suggett, said that to properly recover, affected reefs needed to be connected to those left untouched by bleaching.

He said Hughes’ survey results showed such connectivity was in jeopardy. “It’s that connection ultimately that will drive the rate and extent of recovery,” Suggett said. “So if bleaching events are moving around the [Great Barrier Reef] system on an annual basis, it does really undermine any potential resilience through connectivity between neighbouring reefs.”

Some reef scientists are now becoming despondent. Water quality expert, Jon Brodie, told the Guardian the reef was now in a “terminal stage”. Brodie has devoted much of his life to improving water quality on the reef, one of a suite of measures used to stop bleaching.

He said measures to improve water quality, which were a central tenet of the Australian government’s rescue effort, were failing.

“We’ve given up. It’s been my life managing water quality, we’ve failed,” Brodie said. “Even though we’ve spent a lot of money, we’ve had no success.”

Brodie used strong language to describe the threats to the reef in 2017. He said the compounding effect of back-to-back bleaching, Cyclone Debbie, and run-off from nearby catchments should not be understated.

“Last year was bad enough, this year is a disaster year,” Brodie said. “The federal government is doing nothing really, and the current programs, the water quality management is having very limited success. It’s unsuccessful.”

Others remain optimistic, out of necessity. Jon Day was a director of the Great Barrier Reef Marine Park Authority for 16 years until retiring in 2014.

Day, whose expertise lies in protected area planning and management, said the federal government’s approach to protecting the reef was sorely lacking. He said it was taking too relaxed an approach to fishing, run-off and pollution from farming, and the dumping of maintenance dredge spoil.

The government was far short of the $8.2bn investment needed to meet water quality targets, he said, and Australia was on track to fail its short-term 2018 water quality targets, let alone achieve more ambitious long-term goals.

“You’ve got to be optimistic, I think we have to be,” Day said. “But every moment we waste, and every dollar we waste, isn’t helping the issue. We’ve been denying it for so long, and now we’re starting to accept it. But we’re spending insufficient amounts addressing the problem.”

The Queensland tourism industry raised questions about the reliability of the survey, saying scientists had previously made exaggerated claims about mortality rates and bleaching.

https://interactive.guim.co.uk/charts/embed/apr/2017-04-09T01:14:30/embed.html

“There is no doubt that we have had a significant bleaching event off Cairns this time around,” said Col McKenzie, of the Association of Marine Park Tourism Operators.

“The far north probably did a little bit better, Port Douglas to Townsille has seen some significant bleaching,” he said. “Fortunately we haven’t seen much mortality at this time, and fortunately the temperatures have fallen.”

McKenzie said more money needed to be invested in water quality measures, and criticised what he saw as a piecemeal and uncoordinated approach to water quality projects up and down the coast.

A Brain-Invading Parasite Is Believed to Be Spreading Because of Humans

Health officials in Hawaii have been warning residents not to touch snails or slugs with their bare hands because of an increase in cases of people coming into contact with a rare parasitic infection known as a rat lungworm. Experts are blaming its sudden spread across the United States on climate change and globalization.

In the last two decades, there have only been two documented cases of rat lungworm infections in Hawaii. But in the past three months, six more cases have occurred in rapid succession. Other states where it has recently popped up include California, Alabama, Louisiana and Florida. According to the Atlantic, the first known case of the disease occurred in Taiwan in 1944 but in the past few years, it’s believed to have spread to the U.S. by way of rats in cargo ships.

Pretty much everything about this disease is nasty. Rat lungworm is a parasitic nematode (Angiostrongylus cantonensis) that begins its life as an infection in rat’s lungs, blood, and brains. From there, the rats defecate worm larvae that are spread to other creatures like snails, slugs, and freshwater shrimp. Humans might eat one of these infected hosts or they might eat produce that has had the worm transferred to it by a host. Next thing you know, your brain is being invaded and it doesn’t sound good at all. Once rat lungworm disease moves into the brain it can cause meningitis and its symptoms include tremors, pain, and inflammation. It is often fatal.

The Maui News reported on the recent cases this week and spoke with local residents about the spread of the invasive semi-slug on the island, and the infectious disease that it carries. Locals say that they’ve become increasingly paranoid about eating produce and they line their yards with slug bait. And for an area that thrives on tourism, paranoia about eating the local food can be an economic nightmare.

A local preschool teacher described her experience with parasitic meningitis that was a result of rat lungworm to the Honolulu Civil Beat:

The parasites are in the lining of my brain, moving around. Because I work with children I try to tell stories through word pictures. My visual graphic for what’s happening is that every once in a while somebody opens the top of my head, sets a hot iron inside my brain, then pushes the steam button.

I have a half dozen medicine bottles, several for pain because any movement of my head spikes my pain level to 12. I don’t see any improvement, just that every day is a different day, different pain.

The severity of the disease can vary wildly, there’s no known treatment, and it’s notoriously difficult to diagnose.

Cases of rat lungworm infections have been documented in over 30 countries and health officials are worried about its appearance in areas where previously the habitat was believed to be unsuitable. One recent surprise location was in Oklahoma. Scientists fear that this is just another consequence of climate change. A 2004 World Health Organization report warned that “most new infections seem to be caused by pathogens already present in the environment, which have been brought out of obscurity, or given selective advantage, by changing ecological or social conditions.”

Infectious disease researchers say that some low-income areas of the globe are perfectly situated as transmission zones for tropical diseases that are on the rise. The fear is that these countries are the least prepared to deal with an outbreak. But that doesn’t mean that they aren’t worried about wealthy countries like the United States. We have our own problems because our leaders constantly refuse to acknowledge the threats that come along with climate change. The current head of the Environmental Protection Agency doesn’t believe in climate change and has vowed to destroy environmental regulations. The current budget proposal is hoping to cut the EPA’s funding by 31 percent by focusing on killing climate change programs. And just yesterday, it came to light that the agency was eliminating its climate adaptation program which helps states and localities adjust to the changes that are already occurring their areas. Unfortunately, these fools don’t appear to have a brain parasite, they simply don’t give a shit.

Trump’s big new executive order to tear up Obama’s climate policies, explained

Vicious cycle ties warmer cow food to higher methane emissions

March 30, 2017

As major exponents of greenhouse gases that warm the Earth, what cows consume is increasingly gaining attention from scientists trying to apply the brakes to global methane emissions. The latest promising discovery in this area comes from an international team of researchers, who have found that livestock plant food grown in warmer climates leads to higher methane releases, and could potentially be inhibiting milk and meat production at the same time.

Methane emitted by cows, or from any source for that matter, is a problem because it is 25 times more potent than carbon dioxide as a greenhouse gas, due to its superior heat-trapping abilities. Meanwhile, global meat production is on the rise, from 71 million tons in 1961 to 318 million tons in 2014.

So scientists have been looking at the effects of livestock diets, and how they might be tweaked to reduce the amount of methane produced by the world’s growing bovine population. Last year, Australian scientists identified a strain of seaweed that can reduce methane emissions by 99 percent, while earlier this year another research team discovered that feeding cows tropical leaves in addition to regular food could cause also cause sharp decline.

The latest research doesn’t unearth new dietary supplements, rather it reveals an already existing culprit. Scientists from Royal Botanic Gardens, Kew, Scotland’s Rural College, and the Senckenberg Biodiversity and Climate Research Centre in Frankfurt studied published data on forage quality, and found that nutritional value of grass was reduced at higher temperatures.

This is turn makes it harder for grazing livestock to digest the plants, and the scientists say there are a few reasons that might be. The extra heat causes plants to adapt and they may flower earlier, produce thicker leaves or possibly allow tougher invasive plants to spread into new areas and replace more nutritious species. With the plants tougher to digest, they spend longer inside the animal and produce more gas, and the scientists say this is setting in motion a vicious cycle.

“The vicious cycle we are seeing now is that ruminant livestock such as cattle produce methane which warms our planet,” says Dr. Mark Lee, a research fellow at Royal Botanic Gardens, Kew. “This warmer environment alters plants so they are tougher to digest, and so each mouthful spends more time in the animals’ stomach, producing more methane, further warming the planet, and the cycle continues. We need to make changes to livestock diets to make them more environmentally sustainable.”

With an eye to the future, the scientists used published empirical models to estimate how changes to the climate will impact global methane production. They found that methane production increased by 0.9 percent with a 1 °C temperature rise (1.8 °F), and by 4.5 percent with a 5 °C rise (9 °F). They expect this to be a worldwide trend, but did identify hotspots in North America, Central/Eastern Europe and Asia, places where livestock farming is increasing and climate change is expected to hit hardest.

“Now is the time to act, because the demand for meat-rich diets is increasing around the world,” says Lee. “Our research has shown that cultivating more nutritious plants may help us to combat the challenges of warmer temperatures.”

The research paper was published in the journal Biogeosciences.

Trump wants to make avian flu great again

 http://www.dailykos.com/story/2017/3/30/1648493/-Trump-wants-to-make-avian-flu-great-again

It’s at least a little bit weird how focused Team Trump is on defunding, specifically, the nooks and crannies of the federal government meant to stave off disasters.

First, President Donald Trump and Speaker of the House Paul Ryan pushed a health care plan that would have slashed funding to the Centers for Disease Control and Prevention, the federal agency that tracks farm flu outbreaks and works with the US Department of Agriculture and local authorities to “minimize any human health risk” they cause.That effort collapsed, but now Trump is taking a more direct whack at flu-tracking funding.

The new effort? A $1 billion cut to the Department of Agriculture, plus revoking most of the remaining budget from the 2015 funding to combat that year’s disastrous bird flu epidemic. They plan to use that $50 million, like all their other petty cuts to decent programs, to supersize the military and, we’ll assume, give some specific billionaire yet another tax cut.

Back here in 2017, however, a new avian flu strain is popping back up in multiplestates. It’s too soon to say if it will become a full-on epidemic, but it is a handy reminder that we will undoubtably be spending more money on avian flu, not less.

And the government spends money on these things because not only do they want to avoid a repeat of 2015, when 48 million birds had to be culled from American producers, but because avian flu needs only slight mutations to spread to humans, and we want to avoid a human pandemic.

What’s the Trump-Ryan solution?

Claw back the money meant for those outbreaks, and cut the Department of Agriculture budget by $1 billion dollars, and defund the Affordable Care Act’s Prevention and Public Health Fund, shrinking the CDC’s budget by 12 percent, and cut a whopping $5.8 billion from the National Institutes of Health, just to make good and sure new diseases get a sporting head start on us.
