Summary

Story summary

Chinese Academy of Sciences study published in Science on Aug 6 found collapsing permafrost could impose massive costs that outweigh the Arctic’s economic potential.
The study notes Arctic warming is almost four times faster than average and that 46 percent of northern-hemisphere permafrost lies in Siberia.
Researchers estimate that by 2050 methane emissions from Siberian permafrost thaw and increased wildfires could offset 20 percent of the global methane reduction needed to meet climate targets.
