Melting permafrost increases the emission of greenhouse gases in Arctic lakes

Groundwaters circulating through the subsoil as a result of the melting permafrost can transport carbon dioxide and methane—gases with a strong greenhouse effect—to Arctic lakes, and this increases the effects of climate change. This process of transporting gases to the lakes, which culminates with their emission into the atmosphere, is now quantified for the first time in a paper co-authored by the UAB and published in the journal Nature Communications.
