Scientists built 10 giant chambers around a Minnesota peat bog and warmed it by up to 9°C; within 3 years, every warmed plot switched from storing carbon to releasing it
Peatlands, which store significant global soil carbon, are now releasing it. Warming temperatures cause these ecosystems to shift from carbon accumulators to emitters. This transition occurs rapidly, even with modest warming of four degrees Fahrenheit. Researchers observed carbon loss rates significantly faster than historical accumulation rates. These findings impact global climate forecasting models and future…
