Center for Permafrost (CENPERM)

75-year-old aerial photos reveal that Greenlandic deltas have grown as a result of the warmer climate

About 20% of the Arctic landmass is permafrost, which is permanently frozen soil or rock. Due to global warming permafrost is thawing over large tracts of the Arctic. Thawing increases the decomposition by microorganisms of the enormous stock of organic material stored in permafrost soil. During the decomposition carbon dioxide, methane and other greenhouse gases are released to the atmosphere, potentially increasing global warming. Read more about our research.
