Permafrost underlies 24% of the Northern Hemispheric landmass and contains 60% of global soil carbon. Arctic air temperatures are increasing at approximately twice the global rate, making Arctic permafrost one of the most vulnerable regions to a changing climate. In addition, the frequency and severity of Arctic wildfires are expected to increase throughout the 20th century, with 2020 currently considered the worst Arctic fire year in record.
