Thawing Arctic peatlands risk unlocking huge amounts of carbon

The Artic landscape is changing at an unprecedented pace: in Sweden, Alaska and elsewhere entire towns and villages, houses half sunken into the ground, risk being moved to more stable ground, as the permafrost they had been built on shifts and melts. In the Canadian north, suitable houses have become so rare that apartment prices have skyrocketed, triggering a housing crisis. All around the Arctic, homes lay abandoned, the damage too severe. Roads and other vital infrastructure are at risk, too.
