Where Antarctica's ice melt will have the biggest impact on sea levels
Providence RI (SPX) Nov 27, 2025 When polar ice sheets melt, the effects ripple across the world. The melting ice raises average global sea level, alters ocean currents and affects temperatures in places far from the poles. But melting ice sheets don't affect sea level and temperatures in the same way everywhere. In a new study, our team of scientists investigated how ice melting in Antarctica affects global climate and sea level. We combined computer models of the Antarctic ice sheet, solid Earth and global climate, includ ... read more |

Antarctica's Retreating Ice Reveals Nutrient-Rich Peaks Boosting Ocean Carbon UptakeLondon, UK (SPX) Nov 25, 2025 A new study led by Northumbria University polar scientists has identified a process in East Antarctica that could help lower atmospheric carbon dioxide over extended timescales. As climate change ca ... more 
Sentinel 1D radar satellite returns first images from Antarctic to EuropeBerlin, Germany (SPX) Nov 27, 2025 The Copernicus Sentinel-1D satellite has delivered its first high-resolution radar images, covering glaciers in Antarctica, the southern tip of South America and the German city of Bremen, which wer ... more 
Where Antarctic Ice Melt Will Raise Seas the MostProvidence RI (SPX) Nov 28, 2025 When polar ice sheets melt, the effects ripple across the world. The melting ice raises average global sea level, alters ocean currents and affects temperatures in places far from the poles. B ... more 
Ancient RNA recovery reveals gene activity in Ice Age mammothsBerlin, Germany (SPX) Nov 15, 2025 Researchers from Stockholm University have isolated and sequenced RNA molecules from the tissue of woolly mammoths that lived nearly 40,000 years ago. The study, published in Cell, provides evidence ... more |

Six million year old Antarctic ice reveals deep history of Earth's climateLos Angeles CA (SPX) Oct 29, 2025 A team of US researchers has found the oldest directly dated ice and air samples on Earth in the Allan Hills of East Antarctica. The ice, aged at 6 million years, contains ancient air bubbles that p ... more 
Polar bears sustain arctic scavengers with millions of kilograms of food each yearLos Angeles CA (SPX) Oct 29, 2025 A study published in Oikos highlights polar bears as a cornerstone species for arctic scavengers, showing that their annual hunting activities supply about 7.6 million kilograms of carrion to the re ... more 
Large fluctuations in sea level occurred throughout the last ice ageCorvallis OR (SPX) Oct 17, 2025 Large changes in global sea level, fueled by fluctuations in ice sheet growth and decay, occurred throughout the last ice age, rather than just toward the end of that period, a study publishing this ... more 
Antarctic marine viruses under scrutiny as researchers map unknowns of polar ecosystemsSydney, Australia (SPX) Oct 16, 2025 Antarctic marine viruses have emerged as critical but poorly understood drivers of the Southern Ocean's ecological balance. A new review published in Ocean-Land-Atmosphere Research highlights both r ... more 
Scientists probe Tajik glacier for clues to climate resistanceKon Chukurbashi, Tajikistan (AFP) Oct 13, 2025 Greenland is melting, the Alps are melting and the Himalayas are melting - yet in one vast mountain region, huge glaciers have remained stable, or even gained mass, in recent decades. Can it last? ... more |

UK spearheads polar climate change research as US draws back
Harwich, United Kingdom (AFP) Oct 12, 2025 Britain's flagship polar research vessel heads to Antarctica next week to help advance dozens of climate change-linked science projects, as Western nations spearhead studies there while the United States withdraws. The RRS Sir David Attenborough, a state-of-the-art ship named after the renowned UK naturalist, will aid research on everything from "hunting underwater tsunamis" to tracking glacier melt and whale populations. Operated by the British Antarctic Survey (BAS), the country's polar resear ... read more 
North American ice sheets caused majority of post-Ice Age sea-level riseNew Orleans LA (SPX) Oct 11, 2025 Melting ice sheets in North America were the primary cause of a dramatic global sea-level rise at the end of the last ice age, according to new research led by Tulane University and published in Nat ... more |

Patagonian ice sheet followed its own climatic rhythmBerlin, Germany (SPX) Oct 15, 2025 Patagonia's immense ice fields, stretching hundreds of kilometers along the Andes, are relics of a vast ice sheet that once blanketed southern South America. New research from the University of Brem ... more 
Researchers wake up microbes trapped in permafrost for thousands of yearsBoulder CO (SPX) Oct 06, 2025 In a new study, a team of geologists and biologists led by CU Boulder resurrected ancient microbes that had been trapped in ice - in some cases for around 40,000 years. The study is a showca ... more
Carbon feedback loops could plunge Earth into deep freezeBremen, Germany (SPX) Oct 01, 2025 Until now, the slow weathering of silicate rocks has been considered the planet's primary climate regulator. Rain absorbs atmospheric carbon dioxide (CO2), dissolves exposed rocks, and carries disso ... more 
Swiss glaciers shrank by a quarter in past decade: studyGletsch, Switzerland (AFP) Oct 1, 2025 Switzerland's glaciers, which are disproportionately impacted by climate change, have lost a quarter of their volume in the past decade alone, a study warned Wednesday, heightening concerns over accelerating melting. ... more 
Antarctic sea ice hits its third-lowest winter peak on recordWashington (AFP) Sept 30, 2025 Antarctica's winter sea ice has hit its third-lowest peak in nearly half a century of satellite monitoring, researchers said Tuesday, highlighting the growing influence of climate change on the planet's southern pole. ... more |
