The annual Arctic Report Card is a reminder that what happens in the Arctic affects the rest of the world.
In the Arctic, the freedom to travel, hunt and make day-to-day decisions is profoundly tied to cold and frozen conditions for much of the year. These conditions are rapidly changing as the Arctic warms.
In the annual Arctic Report Card, released Dec. 13, 2022, we brought together 144 other Arctic scientists from 11 countries to examine the current state of the Arctic system.The Arctic is getting wetter and rainierWe found that Arctic precipitation is on the rise across all seasons, and these seasons are shifting.
The Arctic atmosphere is also warming more than twice as fast as the rest of the globe, and this warmer air can hold more moisture.Under the ground, the wetter, rainier Arctic is accelerating the thaw of permafrost, upon which most Arctic communities and infrastructure are built. The result is crumbling buildings, sagging and cracked roads, the emergence of sinkholes and the collapse of community coastlines along rivers and ocean.
Snow is also a travel platform for hunters and a habitat for many animals that rely on it for nesting and protection from predators. In early September 2022, the Greenland ice sheet experienced an unprecedented late-season melt event across 36% of the ice sheet surface. This was followed by another, even later melt event that same month, caused by the remnants of Hurricane Fiona moving up along eastern North America.
