Here’s how Arctic soil offsets emissions from alpine permafrost

Climate change reduces the absorption of greenhouse gases by alpine permafrost but, at the same time, it stimulates CO2 and methane sequestration in Arctic frozen soil, a Chinese study has found. In the first case, global warming potential increases by 13%. In the second, it decreases by 10%
