The study, led by researchers from the University of Cambridge and the University Centre in Svalbard, Norway, identified large stocks of methane gas leaking from groundwater springs unveiled by melting glaciers.
The research suggests that these methane emissions will likely increase as Arctic glaciers retreat and more springs are exposed. This, and other methane emissions from melting ice and frozen ground in the Arctic, could exacerbate global warming.
“These springs are a considerable, and potentially growing, source of methane emissions — one that has been missing from our estimations of the global methane budget until now,” said Gabrielle Kleber, lead author of the research who is from Cambridge’s Department of Earth Sciences.
