Microbiology of thawing permafrost
Permafrost covers 20% of the land area in the northern hemisphere and is estimated to contain half of all soil organic matter on our planet. 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.
This list is by no means exhaustive. Many other projects involving activity or diversity of microorganisms in the Arctic are possible.
