Historical climate effects of permafrost peatland surprise researchers

Peatlands are an important ecosystem that contribute to the regulation of the atmospheric carbon cycle. A multidisciplinary group of researchers investigated the climate response of a permafrost peatland located in Russia during the past 3,000 years. Unexpectedly, the group found that a cool climate period, which resulted in the formation of permafrost in northern peatlands, had a positive, or warming, effect on the climate.
