Experimental warming of a peatland ecosystem showed a rapid shift towards net carbon loss to the atmosphere.
Peatlands cover only about 3 percent of Earth’s land surface but store around 30 percent of global soil carbon. As the climate warms, these carbon stocks are vulnerable to release into the atmosphere as the greenhouse gases carbon dioxide and methane, contributing to a cycle of further warming and carbon release. The SPRUCE (Spruce and Peatland Responses Under Changing Environments...
