7 December 2016 (Columbia University) – Scientists have found evidence in a chunk of bedrock drilled from nearly two miles below the summit of the Greenland Ice Sheet that the ice nearly disappeared for an extended time in the last million years or so. The finding casts doubt on assumptions that Greenland has been relatively […]
By Pam Frost Gorder21 September 2016 COLUMBUS, Ohio (Ohio State University) – The same hotspot in Earth’s mantle that feeds Iceland’s active volcanoes has been playing a trick on the scientists who are trying to measure how much ice is melting on nearby Greenland. According to a new study in the journal Science Advances, the […]
[Jim Hansen’s supralinear sea level rise scenario looks increasingly likely. –Des] By Chris Mooney 17 August 2016 (Washington Post) – In a new study, scientists who study the largest ice mass on Earth — East Antarctica — have found that it is showing a surprising feature reminiscent of the fastest melting one: Greenland. More specifically, […]
By Maria-José Viñas, adapted by Kathryn Hansen4 August 2016 (NASA) – Though it seems counter-intuitive, Greenland’s thick ice sheet actually insulates the bedrock below from the cold air temperatures at the surface. As a result, the bottom of the ice—slowly warmed by heat coming from Earth’s depths—can be tens of degrees warmer than at the […]
By Laura Snider10 August 2016 BOULDER, Colorado (NCAR) – Greenhouse gases are already having an accelerating effect on sea level rise, but the impact has so far been masked by the cataclysmic 1991 eruption of Mount Pinatubo in the Philippines, according to a new study led by the National Center for Atmospheric Research (NCAR). Satellite […]
By Chris Mooney 23 June 2016 (Washington Post) – Here at the Energy and Environment blog, we cover, regularly, the tipping points of climate change — how, for instance, the glaciers of West Antarctica may already have passed a key threshold that leads to unstoppable melt. We cover the history of the Earth’s climate — […]
By Jason Samenow and Angela Fritz 10 June 2016 (Washington Post) – Nuuk, Greenland’s capital, soared to 75 degrees (24 Celsius) Thursday, marking the warmest temperature ever recorded in the Arctic country during June. Nuuk sits on Greenland’s southwest coast, where the country’s warmest weather typically occurs. It was warmer in Nuuk than it was […]
By Joe Romm 15 May 2016 (Climate Progress) – A record fire-storm in Canada fueled by record warmth. Record ice-melt in Greenland and the Arctic sea, driven by off-the-charts warmth in the far north. And, NASA reported Friday, we’ve just been through the hottest April and the hottest January-April on record — by far. Last […]
4 April 2016 (NASA) – Sea level rise is a critical global issue affecting millions across our planet. A new Web portal developed by NASA’s Jet Propulsion Laboratory, Pasadena, California, gives researchers, decision makers and the public alike a resource to stay up to date with the latest developments and scientific findings in this rapidly […]
By Brian Mastroianni23 March 2016 (CBS News) – A sobering new report on the impact of climate change finds that extreme weather like killer storms and high-rising seas could be mere decades, not centuries, away. The report, “Ice Melt, Sea Level Rise, and Superstorms” [pdf] published Tuesday in the journal Atmospheric Chemistry and Physics, says […]
