CryoSat reveals surprising ebb and flow of subglacial lakes
Dec 15, 2020 (ESA)
Meltwater at the underbelly of the ice is not only a result of frictional heating as the ice flows over the bedrock, but also from heat, called geothermal heat,...
What caused the ice ages? Tiny ocean fossils offer key evidence
Dec 14, 2020 (SPX)
"The cause of the ice ages is one of the great unsolved problems in the geosciences," said Daniel Sigman, the Dusenbury Professor of Geological and Geophysical ...
Stockholm sunless so far in December
Dec 10, 2020 (AFP)
At this time of year the sun only rises above the horizon for about six hours a day in the Swedish capital, but this month -- already bleak as the country battl...
Southern Ocean upwelling fuels glacial-interglacial cycles
Dec 10, 2020 (UPI)
These glacial-interglacial cycles correspond with increases and decreases in the concentration of carbon dioxide in the atmosphere, but nobody has been able to ...
Arctic experiences second warmest year since 1900
Dec 08, 2020 (UPI)
The near-record, detailed in the latest edition of NOAA's annual Arctic Report Card, fits into a broader pattern of rising temperatures, shrinking ice sheets, m...
The climate changed rapidly alongside sea ice decline in the north
Dec 07, 2020 (SPX)
During the last glacial period, app. 10,000 - 110,000 years ago the northern hemisphere was covered in glacial ice and extensive sea ice, covering the Nordic se...
Iceberg A-68A: hit or miss
Nov 27, 2020 (ESA)
In July 2017, the lump of ice, more than twice the size of Luxembourg, broke off Antarctica's Larsen C ice shelf - spawning one of the largest icebergs on recor...
Arctic animals' movement patterns are shifting in different ways as the climate changes
Nov 22, 2020 (JPL)
These changes in seasonal timing are already starting - although the shifts differ between species and populations - according to a new study published Nov. 5 i...
Climate change thinning glaciers, increasing oxygen levels at Mount Everest
Nov 20, 2020 (UPI)
Those are just a few of the findings from a suite of new studies -- each detailing various effects of climate change and human activity on Mount Everest -- publ...
Phytoplankton perform photosynthesis, bloom beneath Arctic sea ice
Nov 19, 2020 (UPI)
For decades, scientists assumed phytoplankton in the Arctic go dormant during the winter and early spring, proliferating only after Arctic sea ice begins to rec...
Holes in Greenland ice sheet are larger than previously thought, study finds
Nov 18, 2020 (SPX)
The extra volume could influence the stability of the Greenland ice sheet and how quickly it slides toward the sea. The team studied the relationship between th...
Greenland's largest glaciers likely to melt faster than feared: study
Nov 17, 2020 (AFP)
Until 2000, the main driver of sea level rise was melting glaciers and the expansion of ocean water as it warms. But over the last two decades, the world's ice ...
Russia to launch first satellite to monitor Arctic climate in February 2021
Nov 16, 2020 (Sputnik)
In October, a spokesperson for the Russian space corporation Roscosmos told Sputnik that the launch of Arktika-M had been delayed until 2021 over the need for a...
Possible 1,000-kilometer-long river running deep below Greenland's ice sheet
Nov 13, 2020 (SPX)
Radar surveys have previously mapped Greenland's bedrock buried beneath two to three thousand meters of ice. Mathematical models were used to fill in the gaps i...
Atmospheric rivers help create massive holes in Antarctic sea ice
Nov 12, 2020 (SPX)
Scientists studied the role of long, intense plumes of warm, moist air - known as atmospheric rivers - in creating enormous openings in sea ice. They focused on...
Scientists have discovered an ancient lake bed deep beneath the Greenland ice
Nov 11, 2020 (SPX)
Apparently formed at a time when the area was ice-free but now completely frozen in, the lake bed may be hundreds of thousands or millions of years old, and con...
Giant berg on collision course with South Georgia
Nov 11, 2020 (ESA)
Over the last three years, satellite missions such as Copernicus Sentinel-1 have been used to track the berg as it has drifted in the Southern Ocean. For the fi...
Mystery of glacial lake floods solved
Nov 09, 2020 (SPX)
The mystery involves floods or "jokulhlaups" that emerge suddenly and unpredictably from glaciers or ice caps like those in Iceland where volcanic heat melts th...
The Anatomy of Glacial Ice Loss
Nov 06, 2020 (JPL)
Glaciers and ice sheets are far more complex structures than ice cubes. They form when snow accumulates and is compressed into ice by new snow over many years. ...
Massive iceberg threatens remote penguin sanctuary
Nov 04, 2020 (AFP)
Icebergs naturally break off from Antarctica into the ocean, but climate change has accelerated the process -- in this case, with potentially devastating conseq...
