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.
With sea ice reduced, polar bears in the Arctic are spending more time on land, leading to increased attacks on people. Concerned Inuit communities want to increase hunting quotas, but researchers are testing new technologies they hope will reduce these often deadly confrontations.
Sargassum is free-floating brown macro-algae that lives in the temperate and tropical oceans of the world. In the open ocean, the floating seaweed provides important ecosystem services by acting as habitats for a diverse group of marine animals. It provides food, shade, and shelter to many types of specialized fish, crustaceans, and turtles.
Palsmyr is threatened by climate change. At Ferdesmyra in Finnmark, the characteristic ice-filled pals that protrude from the terrain will be gone in a few years.
