Peatlands are an important ecosystem that contribute to the regulation of the atmospheric carbon cycle. A multidisciplinary group of researchers, led by the University of Helsinki, 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.
