The latest international research: record breaking melting level of Greenland ice sheet in 2019

Beijing, August 21 (reporter Sun Zifa) – a climate science research paper published by Springer nature’s professional academic journal communication earth and environment pointed out that Greenland’s ice mass loss in 2019 was 15% more than the ice melting record set in 2012. Between 2003 and 2019, the amount of ice melting in 2017-2018 is less than in any other two years. < / P > < p > according to the paper, melting Greenland ice sheet is one of the biggest causes of sea-level rise, with the global average sea level rising by about 3.5 mm from 2005 to 2017, of which about 0.76 mm per year is related to the Greenland ice sheet. The gravity recovery and Climate Experiment (GRACE) satellite mission and its successor grace-fo make it possible to quantify ice mass loss by tracking gravity changes. The paper was published by the Institute of communication in Germany Sasgen) and the collaborators analyzed the data of grace and grace-fo missions from 2003 to 2019, and found that Greenland’s ice melting volume in 2017 and 2018 was extremely low, but the ice melting volume in 2019 reached a record breaking 532 billion tons. Using simulations and a regional climate model, they attributed the low melting ice from 2017 to 2018 to the cold summer in western Greenland and high snowfall in the East. < / P > < p > in a “news and views” article published simultaneously in nature climate change, some peer experts believe that it is very important to understand and closely monitor the material balance change of Greenland ice sheet, and INGO sasgen and its collaborators have taken an important step in this direction. Greenland is now under the jurisdiction of Denmark. According to a press release issued by the Danish Meteorological Institute on the 18th, an international research team analyzed the data of ice sheet melting in recent 30 years and found that if the current rate of climate warming is maintained, Greenland ice sheet will continue to melt, and the global sea level will rise by at least 10 cm by 2100.
