A study led by the University of Exeter indicates that Arctic peatlands are expanding, with margins shifting over a meter per year since 1950. The research, based on peat cores from 91 locations, shows that these ecosystems now cover a larger area than in the past 200-300 years.

Warmer conditions promote plant growth, which aids in peat formation. While peatlands store significant carbon, the researchers caution that future warming may lead to degradation and carbon release. The study is part of the ICAAP project funded by the UK Natural Environment Research Council.
