How Thawing Permafrost Creates a Climate Feedback Loop
Rising global temperatures are thawing Arctic permafrost, releasing vast stores of ancient organic carbon as greenhouse gases like CO2 and methane. This process creates a self-reinforcing feedback loop, where released gases cause further warming, leading to more permafrost thaw and accelerated climate change.
