ESA and NASA collaborate to track Greenland ice sheet melting
Paris, France (SPX) Dec 23, 2024 As global warming accelerates the melting of the Greenland Ice Sheet, its contribution to rising sea levels and disruptions in global weather patterns underscores the need for precise monitoring. For the first time, data from ESA's CryoSat and NASA's ICESat-2 missions have been combined to create a detailed picture of the ice sheet's changing shape. The two satellites employ distinct technologies to measure surface height. CryoSat uses radar altimetry, capable of penetrating clouds and ice surface ... read more |

Antarctic sea ice can be explained and forecast months out by patterns in windsSeattle WA (SPX) Dec 09, 2024 Amid all the changes in Earth's climate, sea ice in the stormy Southern Ocean surrounding Antarctica was, for a long time, an odd exception. The maximum winter sea ice cover remained steady or even ... more 
Will the Ross Ice Shelf meltLos Angeles CA (SPX) Dec 09, 2024 An international team of scientists, including researchers from Binghamton University, State University of New York, has launched a critical mission to uncover geological records from the West Antar ... more
Canada bolstering Arctic presence in face of Russia threatOttawa (AFP) Dec 6, 2024 Canada will boost its military and diplomatic presence in the Arctic to counter what it calls threats from Russia and others seeking a foothold in the far north, as part of a new doctrine unveiled Friday. ... more 
Scientists launch first in-depth study of Antarctic underwater avalanchesLondon, UK (SPX) Dec 06, 2024 Scientists are set to explore Antarctica's underwater avalanches, also known as turbidity currents, in an international effort to understand their role in Earth's climate regulation. The Antarctic C ... more 
Recent global temperature surge amplified by record-low planetary albedoBerlin, Germany (SPX) Dec 06, 2024 Rising sea levels, melting glaciers, and record-breaking marine heatwaves defined 2023 as a year of extraordinary climate shifts.

Under-ice species face threat as Arctic ice melts
London, UK (SPX) Dec 03, 2024 Specialized lifeforms that thrive beneath Arctic sea ice face increasing risk as the ice continues to retreat, according to new research conducted by an international team of scientists. The study focused on microscopic organisms in four distinct habitats of the Beaufort Sea in northern Canada: open ocean, river mouths, coastal waters, and areas beneath sea ice. Researchers found that the under-ice communities exhibited the lowest diversity, consisting primarily of specialist plankton and microbes ... read more 
Researchers link Arctic warming to rising dust emissions impacting cloud formationTokyo, Japan (SPX) Dec 03, 2024 The Arctic is warming at a rate two to four times higher than the global average, revealing complex interactions between temperature changes and atmospheric conditions.
