Permafrost peat carbon approaching a climatic tipping point

Nature Climate Change, Published online: 14 March 2022; doi:10.1038/s41558-022-01298-5

Vast areas of carbon-dense, permafrost peatlands are known to be at risk from warming climates, but models indicate that they are closer to widespread climatic degradation than previously believed. All but the most aggressive climate mitigation scenarios will render these carbon hotspots climatically unsustainable across Europe and Western Siberia within decades.
