The thawing of permafrost suggested to be just moderately hazardous to the climate

Researchers from the Siberian Branch of the Russian Academy of Sciences, together with foreign colleagues, studied the factors that affect the decomposition of organic matter in melting permafrost. It turned out that carbon, which is being released by bacteria and fungi, does not necessarily takes the form of СО2. The article describing the results of the study is published in the Global Change Biology.

There are hypotheses that as the permafrost warms and thaws, the carbon stored in the organic material will be released, enter the food chains and then get into the atmosphere in the form of СО2. The process will accelerate the warming even more.

The scientists conducted an experiment by heating parts of the permafrost, and found that it almost does not lose any carbon. It turned out that most of the carbon remains bound in mineral-organic complexes, which are inaccessible to bacteria and fungi.

This means that the melting of permafrost will not lead to a sharp release of СО2 into the atmosphere and therefore will not exacerbate the problem of the stability of the Earth’s climate.
