The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different satellite estimates, researchers found that Greenland’s melt has gone into hyperdrive in the last few years. Greenland’s average annual melt from 2017 to 2020 was 20% more a year than at the beginning of the decade and more than seven times higher than its annual shrinkage in the early 1990s.
the acceleration in the melting of the earth s ice sheets is now unmistakable. the international group of experts say the planet was much principles lost 7000 560 billion tonnes in mass over the past 50 years. mass lost from greenland might be a mass loss from greenland and other polar areas is now a quarter of the ice sheets. let s now talk to a scientist who is part of this modelling. thank you forjoining us, how worrying it is this? . ., ., a this? thanks for having me. as you said, this? thanks for having me. as you said. doing this? thanks for having me. as you said, doing satellite this? thanks for having me. as you said, doing satellite observations i said, doing satellite observations we found that the antarctic and arctic have lost a very huge amount of ice and to put this very large number into perspective, this is enough ice to fill cubes that would be 20 kilometres in height. this is really important because we found that there has been acceleration in ice loss and i
