🧊 Rising air temperatures amplify the effects of melting caused by ocean warming, leading to greater ice loss from the world’s second-largest ice sheet, a new study reveals. Researchers from the Universities of Edinburgh and California San Diego have evaluated submarine melting of the Greenland ice sheet over a 40-year period from 1979 to 2018. To determine the impact of both warming air and seas on ice sheet loss they used observational data and computer modelling to analyse the effect each had on submarine melting. The team found that air temperature has had almost as much impact as ocean temperature on submarine melting, with some regional variations. This unfortunately adds to the overwhelming body of evidence showing the sensitivity of the Greenland ice sheet to climate change, hence the need for urgent action to reduce greenhouse gas emissions.
