By Katherine J. Wu 17 July 2019 (PBS) – Gird your loins, humans: The time has come to turn part of the South Pole into our own giant snow globe. Or has it? In a study published today in the journal Science Advances, a team of German researchers suggests that dumping 8 trillion tons of artificial snow onto […]
By Carolyn Beeler 13 May 2019 (PRI) – Peter Sheehan, an oceanographer on the Nathaniel B. Palmer, was one of the first people on Earth to get this view of Thwaites Glacier — the part that juts out to sea. He’s pored over plenty of Google images of ice shelves, but there’s nothing like the […]
By Jonathan Bamber and Michael Oppenheimer 20 May 2019 (The Conversation) – Antarctica is further from civilisation than any other place on Earth. The Greenland ice sheet is closer to home but around one tenth the size of its southern sibling. Together, these two ice masses hold enough frozen water to raise global mean sea […]
16 May 2019 (University of Leeds) – In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that 24 percent of its glacier ice is now affected, according to a new study. By combining 25 years of European Space Agency satellite altimeter measurements and a model of the […]
By Jennifer Chu 6 May 2019 (MIT News) – Virtually all marine life depends on the productivity of phytoplankton — microscopic organisms that work tirelessly at the ocean’s surface to absorb the carbon dioxide that gets dissolved into the upper ocean from the atmosphere. Through photosynthesis, these microbes break down carbon dioxide into oxygen, some […]
By Rafi Letzter 23 April 2019 (Live Science) – Greenland’s ice sheet is melting six times faster than it was in the 1980s. And all that meltwater is directly raising sea levels. That’s all according to a new study, published yesterday (22 April 2019) in the journal Proceedings of the National Academy of Sciences, that […]
By Matteo Willeit 3 April 2019 (RealClimate) – A new study published in Science Advances shows that the main features of natural climate variability over the last 3 million years can be reproduced with an efficient model of the Earth system. The Quaternary is the most recent geological Period, covering the past ~2.6 million years. It is defined […]
By Navin Singh Khadka 21 March 2019 (BBC News) – Expedition operators are concerned at the number of climbers’ bodies that are becoming exposed on Mount Everest as its glaciers melt. Nearly 300 mountaineers have died on the peak since the first ascent attempt and two-thirds of bodies are thought still to be buried in […]
IRVINE, California, 14 January 2019 (UCI) – Antarctica experienced a sixfold increase in yearly ice mass loss between 1979 and 2017, according to a study published today in Proceedings of the National Academy of Sciences. Glaciologists from the University of California, Irvine, NASA’s Jet Propulsion Laboratory and the Netherlands’ Utrecht University additionally found that the […]
By Lauren C. Andrews2 January 2019 (Nature) – Sediments beneath glaciers and ice sheets harbour carbon reserves that, under certain conditions, can be converted to methane, a potent greenhouse gas. However, the formation and release of such methane is an unquantified component of the Arctic methane budget. Writing in Nature, Lamarche-Gagnon et al.1 present direct […]
