The IPCC Cryosphere Synthesis (IPCC 2019) provides information on the increase in permafrost temperatures since the 1980s. From 2007 to 2016, permafrost temperatures increased by an average of 0.29°C ± 0.12°C in the polar and high mountain regions of the world. The intensity of climate warming in the Arctic is exacerbated by this melting of Arctic and boreal permafrost, which may eventually release between 1,460 and 1,600 Gt of organic carbon, nearly twice the carbon in the atmosphere (IPCC 2019).
