Abstract: We analysed the effect of the 2018 European drought on greenhouse gas (GHG) exchange of five North European mire ecosystems. The low precipitation and high summer temperatures in Fennoscandia led to a lowered water table in the majority of these mires. This lowered both carbon dioxide (CO <subscript>2</subscript> ) uptake and methane (CH <subscript>4</subscript> ) emission during 2018, turning three out of the five mires from CO <subscript>2</subscript> sinks to sources. The calculated radiative forcing showed that the drought-induced changes in GHG fluxes first resulted in a cooling effect lasting 15-50 years, due to the lowered CH <subscript>4</subscript> emission, which was followed by warming due to the lower CO <subscript>2</subscript> uptake. This article is part of the theme issue 'Impacts of the 2018 severe drought and heatwave in Europe: from site to continental scale'.
