Of all the things that might be uncovered by melting permafrost, the most frightening is invisible. Permafrost is a huge natural reservoir of methane, a potent greenhouse gas much more effective than carbon dioxide at trapping heat and warming the planet. Siberian permafrost melting. At the same time, the wildfires and sustained heatwaves accelerated the region's permafrost melt. Using maximum and minimum values for the variable in the melt equation, I obtained a best estimate of the average melt rate along the periphery (a 400-mile [645-km] long strip) of the ice sheet in North America at about 33 feet/year (10 m/year). Less than one-fifth of the permafrost zone is likely to see this abrupt thawing, but its impact on the surrounding landscape means up to half of permafrost carbon could be affected. As the frozen ground warms much faster than expected, itâs reshaping the landscapeâand releasing carbon gases that fuel global warming.
