Groundwaters that circulate through the subsoil as a result of melting permafrost can transport carbon dioxide and methane to Arctic lakes and in turn be emitted to the atmosphere. This process of transporting greenhouse gases increases the effects of climate change and is now being quantified for the first time by researchers from the universities in Umeå, Barcelona, and Linköping. The study is published in Nature Communications.
