Rising Global Temperatures Accelerate Melting Of The Greenland Ice Sheet

KANGERLUSSUAQ, GREENLAND - JULY 11: In this aerial view, rivulets of meltwater snake across the surface of the melting Isunnguata Sermia glacier of the Greenland Ice Sheet on July 11, 2024 near Kangerlussuaq, Greenland. A team of scientists has observed that increasing amounts of meltwater on the surface of the glacier making their way to the glacial flows underneath are leading to a rising output of methane from Isunnguata Sermia. Earlier this year other scientists published a study in which they concluded that Greenland’s glaciers, which all stem from the Greenland Ice Sheet, have retreated about 20% more than previously estimated. Of the 200 glaciers included in the study, only one has grown since 1985. Overall, the amount of glacial ice melting globally has increased markedly over the past 30 years as global warming continues to intensify. According to the European Space Agency, the Earth lost 28 trillion tons of ice between 1994 and 2017, enough to cover the entire United Kingdom with an ice sheet 100 meters thick. Since 2017 the rate of ice loss has increased to 1.3 trillion tons annually, up from 0.8 trillion tons in the 1990s. According to the Programme for Monitoring of the Greenland Ice Sheet (PROMICE), the Greenland Ice Sheet has been losing mass continuously since 1996, with an accumulated loss since 1986 approaching 6,000 metric gigatons, or six trillion tons.
