PARIS: Greenland's massive ice sheet saw a record net loss of 532 billion tonnes last year, raising red flags about accelerating sea level rise, according to findings released Thursday. That is equivalent to an additional three million tonnes of water streaming into global oceans every day, or six Olympic pools every second.
Crumbling glaciers and torrents of melt-water slicing through Greenland's two-to-three-kilometre thick ice block were the single biggest source of global sea level rise in 2019, accounted for 40 percent of the total, or 1.5 millimetres, researchers reported in the journal Communications Earth & Environment.
Last year's loss of mass was at least 15 percent above the previous record in 2012, but even more alarming are the long-term trends, they said. "2019 and the four other record-loss years have all occurred in the last decade," lead author Ingo Sasgen, a glaciologist at the Helmholtze Centre for Polar and Marine Research in Germany, told AFP.
