Study: Arctic soils store more methane than assumed

According to a recent study, the impact of the greenhouse gas methane from Arctic soils on the Earth’s atmosphere may have been slightly overestimated. Due to the drier soil, soils at higher levels in the Arctic apparently absorb significantly more of the potent greenhouse gas methane than previously assumed. This is what a team of researchers led by Carolina Voigt from the University of Eastern Finland in Kuopio wrote in the Nature journal. They describe a „negative feedback,“ i.e., a self-reinforcing development that binds more greenhouse gas than previously believed.
