Not good.
The rapid change in North American permafrost is equally alarming. “In some places in the Alaskan Arctic, you fly over a swiss cheese of land and lakes formed by ground collapse,” says Natali, whose fieldwork has moved from Siberia to Alaska. “Water that was close to the surface now becomes a pond.” Many of these ponds are bubbling with methane, as microbes suddenly find themselves with a feast of ancient organic matter to munch on, releasing methane as a by-product. “We often walk across the lakes because it’s so shallow and it’s like you’re in a hot tub in some places, there is so much bubbling,” says Natali.
