Permafrost climate tipping point threshold at 1.5 degrees Celsius - Siberian caves reveal
Takver - Climate IMC
At what point might we trigger a permafrost tipping point? New research from the caves of Siberia points to a threshold temperature of just 1.5 degrees celsius. At that temperature we could see large swathes of permafrost across Siberia melting resulting in the release of more than 1,000 gigatons of carbon and methane. This would be a substantial climate feedback resulting in even greater global warming. There would also be substantial damage to natural and human environments and structures.
