Arctic Permafrost Thaw Unleashes Ancient Carbon: How a Climate Feedback Loop Fuels Runaway Warming
Nature World News | 21.04.2026 08:14
Global temperatures climb, and Arctic permafrost thaw picks up speed, unleashing ancient carbon release that feeds a relentless climate feedback loop. Frozen soils across the north, holding organic matter from long-extinct ecosystems, melt under warmer conditions, sending dissolved carbon into rivers and eventually the ocean. This cycle traps more heat, speeding up the thaw even further.
