Scientists have discovered an ancient lakebed deep beneath the Greenland ice（图）
Scientists ancient lakebed deep beneath Greenland ice
2020/11/20
Scientists have detected what they say are the sediments of a huge ancient lakebed sealed more than a mile beneath the ice of northwest Greenland -- the first-ever discovery of such a sub-glacial feat...
Greenland is on track to lose ice faster this century than in any other over the past 12,000 years（图）
Greenland lose ice faster century past 12,000 years
2020/10/10
Greenland's rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes.The U.S. National Science Foundation-supported researc...
Greenland Ice Sheet meltwater can flow in winter, too（图）
Greenland Ice Sheet meltwater flow winter
2020/4/17
Liquid meltwater can sometimes flow deep below the Greenland Ice Sheet in winter, not just in summer, according to National Science Foundation-funded research published in the American Geophysica...
Ice is sliding toward edges of Greenland Ice Sheet（图）
Ice toward edges Greenland Ice Sheet
2019/10/23
Ice on the Greenland Ice Sheet doesn’t just melt. The ice slides rapidly across its bed toward the ice sheet’s edges. As a result, ice is moving to high-melt marginal zones more rapidly than previousl...
New research shows an iceless Greenland may be in the future（图）
iceless Greenland future greenhouse gas ice sheet
2019/10/28
New research shows that an iceless Greenland may be in the future. If worldwide greenhouse gas emissions remain on their current trajectory, Greenland may be ice-free by the year 3000. By the end of t...
Research shows ice sheets as large as Greenland’s melted fast in a warming climate（图）
ice sheets as large as Greenland’s melted fast warming climate
2017/11/24
New research published in Science shows that climate warming reduced the mass of the Cordilleran Ice Sheet by half in as little as 500 years, indicating the Greenland Ice Sheet could have a similar fa...
New maps of Greenland’s coastal seafloor and bedrock beneath its massive ice sheet show that two to four times as many coastal glaciers are at risk of accelerated melting as had previously been though...
A history of snowfall on Greenland,hidden in ancient leaf waxes
history of snowfall Greenland ancient leaf waxes
2016/5/31
The history of Greenland’s snowfall is chronicled in an unlikely place: the remains of aquatic plants that died long ago, collecting at the bottom of lakes in horizontal layers that document the passi...
Researchers from MIT, Princeton University, and elsewhere have developed a new technique to monitor the seasonal changes in Greenland’s ice sheet, using seismic vibrations generated by crashing ocean ...
UGA researchers discover fate of melting glacial ice in Greenland
UGA researchers melting glacial ice Greenland
2016/5/6
Over the past several decades, scientists have observed a significant increase in the melting of glacial land ice on the island of Greenland, spurring concerns about global sea level rise and the long...
Climate Change:Greenland Melting Tied to Shrinking Arctic Sea Ice
Climate Change Greenland Melting Shrinking Arctic Sea Ice
2016/4/13
Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island.These dramatic trends and global sea-level rise are linked, according to a study co...
Two Lakes Beneath the Ice in Greenland, Gone Within Weeks
Two Lakes Beneath the Ice Greenland Gone Within Weeks
2015/3/4
Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly dr...
Melting of glacial ice will probably raise the sea level around the globe, but how fast this melting will happen is uncertain. Greenland is especially pivotal in the study of melting ice sheets and ri...
“Probabilistic calibration of a Greenland Ice Sheet model using spatially resolved synthetic observations: toward projections of ice mass loss with uncertainties” published in Geosci. Model Dev., 7, 1933–1943, 2014
Greenland Ice Sheet spatially resolved synthetic observations
2014/12/19
Due to an oversight in the production process, the article “Probabilistic calibration of a Greenland Ice Sheet model
using spatially resolved synthetic observations: toward projections of ice mass lo...
Holocene Paleo-environmental Variability Reconstructed from a Lake Sediment Record from Southeast Greenland
Holocene Paleoenvironmental Variability Reconstructed a Lake Sediment Record Southeast Greenland
2014/10/21
Arctic climate variability over the Holocene has been both extensive and, at times, abrupt. Current understanding of these changes is still quite limited with few highresolution paleoclimate records a...
