Antarctica's ice melt isn't consistent, new analysis shows
Antarctic ice is melting, contributing massive amounts of water to the world's seas and causing them to rise - but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years' worth of satellite data indicates. (2021-02-01)

Greenland ice sheet faces irreversible melting
Scientists predict Greenland ice sheet will pass a threshold beyond which it will never fully regrow and sea levels will be permanently higher in as little as 600 years under current climate change projections, as Greenland's climate would be permanently altered as the ice sheet shrinks. (2020-12-02)

What will the climate be like when earth's next supercontinent forms?
The continents will reunite again in the deep future. And a new study, presented today during an online poster session at the meeting of the American Geophysical Union, suggests that the future arrangement of this supercontinent could dramatically impact the habitability and climate stability of Earth. The findings also have implications for searching for life on other planets. (2020-12-01)

Shift in atmospheric rivers could affect Antarctic sea ice, glaciers
Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research published in the AGU journal Geophysical Research Letters.

Unusually clear skies drove record loss of Greenland ice in 2019
Last year was one of the worst years on record for the Greenland ice sheet, which shrunk by hundreds of billions of tons. According to a study published today in The Cryosphere, that mind-boggling ice loss wasn't caused by warm temperatures alone; the new study identifies exceptional atmospheric circulation patterns that contributed in a major way to the ice sheet's rapid loss of mass.

Artificial snowfall could save the west antarctic ice sheet, but with high costs and risks
By pumping ocean water onto coastal regions surrounding parts of the West Antarctic ice sheet and converting it to snow, it may be possible to prevent the ice sheet from sliding into the ocean and melting, according to a new modeling study. The authors caution that while the findings offer a potentially feasible and less dangerous solution compared to other proposed. (2019-07-17)

West Antarctic ice collapse may be prevented by snowing ocean water onto it
The ice sheet covering West Antarctica is at risk of sliding off into the ocean. While further ice-sheet destabilisation in other parts of the continent may be limited by a reduction of greenhouse gas emissions, the slow, yet inexorable loss of West Antarctic ice is likely to continue even after climate warming is stabilised. A collapse might take hundreds of years but will raise sea levels worldwide by more than three meters. (2019-07-17)

A clearer picture of global ice sheet mass
Fluctuations in the masses of the world's largest ice sheets carry important consequences for future sea level rise, but understanding the complicated interplay of atmospheric conditions, snowfall input and melting processes has never been easy to measure due to the sheer size and remoteness inherent to glacial landscapes. (2019-07-09)

Passing aircraft wring extra snow and rain out of clouds
Planes flying over rain or snow can intensify the precipitation by as much as 10-fold, according to a new study.
