Hidden Carbon Releases From Thawing Lands and Burning Forests Threaten to Boost Warming by 30%

A major new study finds that emissions from thawing permafrost, wildfires, wetlands and inland waters could amplify global warming by 20-30% this century. The overlooked processes add 0.2-0.4°C by 2100 on top of human-caused heating, tightening carbon budgets and demanding faster emissions cuts. The findings update climate models used for policy.
