Forscher untersuchen das Schmelzen des grönländischen Eisschildes / 2018 *** Meltwater canyon on the Greenland ice sheet. See National story NNmelt; Greenland's ice sheet is melting at a scale "off the charts" compared with the previous four centuries, warns a new study. Researchers say that if the Greenland ice sheet melting continues at "unprecedented rates" - which they attribute to warmer summers - it could accelerate the already fast pace of sea level rise. Surface melting across Greenland's mile-thick ice sheet began increasing in the mid-19th Century and then ramped up dramatically during the 20th and early 21st Centuries - and shows no signs of abating, according to the study. Scientists say their findings, published in the journal Nature, provide new evidence of the impacts of climate change on Arctic melting and global sea level rise. Study lead author Dr Luke Trusel, a glaciologist at Rowan University in the United States, said: "Melting of the Greenland Ice Sheet has gone into overdrive. "As a result, Greenland melt is adding to sea level more than any time during the last three-and-a-half centuries, if not thousands of years. "And increasing melt began around the same time as we started altering the atmosphere in the mid-1800s." *** Local Caption ***
