Rapid climate change has made Greenland lose a record amount of ice

Greenland glacier loses 110 square kilometres’ worth of ice, ABC, 14 Sept 20, A chunk of Greenland’s ice cap estimated to be
Scientists say the incident is evidence of rapid climate change. The glacier section broke off the fjord called Nioghalvfjerdsfjorden, which is about 80 kilometres long and 20 kilometres wide, the National Geological Survey of Denmark and Greenland (GEUS) reported. The glacier is at the end of the north-east Greenland ice stream, where it flows off land into the ocean. Annual end-of-melt-season changes for the Arctic’s largest ice shelf in the region are measured by optical satellite imagery. GEUS showed area losses for the past two years each exceeded 50 square kilometres. “We should be very concerned about what appears to be progressive disintegration at the Arctic’s largest remaining ice shelf,” GEUS professor Jason Box said……. In August, a study showed that Greenland lost a record amount of ice during an extra-warm 2019, with the melt massive enough to cover the US state of California in more than 1.25 metres of water. https://www.abc.net.au/news/2020-09-14/chunk-of-greenlands-ice-cap-has-broken-off/12663510 |
