Methane release from carbonate rock formations in the Siberian permafrost area during and after the 2020 heat wave

A positive response from the mobilization of methane from the thawing Arctic permafrost may have accelerated Anthropogenic global warming. Methane can only be produced from organic matter within the thawing permafrost soils, but it can also be obtained from natural gas trapped under or within the permafrost layer and released when it thaws. During and after the 2020 heat wave, atmospheric methane levels in the Taymyr Peninsula and surrounds in North Siberia, the area with the world's highest positive surface temperature anomaly for 2020, have risen noticeably. Two elongated areas of elevated atmospheric methane concentration during summer coincided with two stripes of Paleozoic carbonate exposed along the southern and northern boundaries of the Yenisey-Khatanga Basin, a hydrocarbon-bearing sedimentary basin between the Siberian Craton to the south and the Taymyr Fold Belt to the north, and the Taymyr Fold Belt to the north.
