The permafrost layer in the arctic is starting to thaw. How will the affect global warming?
Behind the door is a geological time bomb, scientists say. No one knows exactly how big the bomb is. It may even be a dud that barely detonates. But the fallout could be so large that it’s felt all around the world. Now there’s evidence that, in the past few years, the bomb’s timer has started ticking.
This is a terrifying read. The permafrost in the arctic contains a massive amount of organic material that has been frozen for 25,000 years. As global temperatures rise, thawing the permafrost, bacteria trapped in the frost will activate and start breaking down the organic material.
Kind of like how if your neighbor’s dog takes a poo on the sidewalk outside your house in the winter, and your neighbor doesn’t clean it up, and the poo gets covered in snow… it’s still there in spring when everything thaws, ready to start breaking down. Only it’s literally mammoth poop and a lot of it (and other things). Anyways – glad to get that out there. Global warming is scary and my neighbors really need to do a better job cleaning up after their dog.
