Antarctica and “alarming” Sea Level Rise

By Rud Istvan, WUWT reader KS of North Dakota emailed a request to ctm based on reading ‘alarming’ Wired journalism concerning $50 million being spent to further study the ‘dangerous’ Thwaites glacier in Antarctica. KS asked if WUWT could perhaps produce a factual overview. ctm asked me to provide it, since I had written an…

NASA flights gauge summer sea ice melt in the Arctic

  From NASA By Maria-Jose Viñas, NASA’s Earth Science News Team Earlier this year, Arctic sea ice sank to a record low wintertime extent for the third straight year. Now NASA is flying a set of instruments north of Greenland to observe the impact of the melt season on the Arctic’s oldest and thickest sea…

Enormous Aquifer Discovered Under Greenland Ice Sheet

From NASA, I had to laugh at this statement: The water in the aquifer has the potential to raise global sea level by 0.016 inches (0.4 mm). That’s assuming it can get out sometime in the distant future. Greenland’s topography under the ice is bowl shaped. =================================== Buried underneath compacted snow and ice in Greenland…

Negative feedback? Storing CO2 in the Arctic

From the Massachusetts Institute of Technology: While the Arctic Ocean is largely a carbon sink, researchers find parts are also a source of atmospheric carbon dioxide For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent…

Lakes discovered beneath Greenland ice sheet

From the University of Cambridge The subglacial lakes are the first to be identified in Greenland The study, published in Geophysical Research Letters, discovered two subglacial lakes 800 metres below the Greenland Ice Sheet. The two lakes are each roughly 8-10 km2, and at one point may have been up to three times larger than…
