About 75 years ago, a reindeer fell sick to anthrax. Laying down to die upon the frozen ground of Siberia, the poor creature’s carcass froze in the Arctic climate. With it, the deadly infectious bacteria teeming in the deer’s body were stilled into an inert latency.
In the decades after, billions of tons of carbon bellowed out into the world’s air from fossil-fuel burning and carbon-spewing machines spreading around the globe. The heat-trapping properties of these carbon gasses subsequently warmed the Arctic and the frozen permafrost that was this ill-fated deer’s — and the anthrax’s — tomb.
(Extent of Northern Hemisphere permafrost. Due to human-forced climate change, this permafrost zone is starting to thaw. At about 2 C worth of warming, a majority of this region will be under thaw pressure. Thawing permafrost releases carbon dioxide and methane, unearths ancient diseases, and causes the ground overlaying the permafrost to collapse. Image source:
