Grei påminnelse om hvorfor permafrost som tiner er en av de mest bekymringsverdige konsekvensene av klimaendringene
Thawing permafrost is among climate science’s worst “positive feedback loops”: As the world warms, permafrost—essentially frozen soil—thaws, releasing fresh water and carbon into the environment. That release further fuels climate change, driving more warming. (Thawing permafrost has also raised concerns about unleashing new pathogens on humanity.)
And in Alaska, the loop seems to be speeding up. In a new study, researchers tracked how thawing permafrost in a Wisconsin-sized section of the North Slope region of Alaska has added fresh water and dissolved organic carbon to estuaries off the Alaskan coast between 1980 and 2023. http://spklr.io/6000EytWO
