Washington Post: For many scientists studying Antarctica, and particularly the vulnerable West Antarctic ice sheet, a major new study significantly increasing expectations for sea-level rise is the culmination of a large body of prior research -- combined with alarming recent observations. The study, just published in Nature, is based on an improved understanding of past warm eras in Earths history that featured much higher seas. By creating advanced computer simulations of how Antarcticas ice melts and flows...

Scientists nearly double sea level rise projections for 2100, because of Antarctica

Washington Post: Sea levels could rise nearly twice as much as previously predicted by the end of this century if carbon dioxide emissions continue unabated, an outcome that could devastate coastal communities around the globe, according to new research published Wednesday. The main reason? Antarctica. Scientists behind a new study published in the journal Nature used sophisticated computer models to decipher a longstanding riddle about how the massive, mostly uninhabited continent surrendered so much ice during...

Antarctic Melt Surges Sea Level in Climate Change Recalculation

2016-03-31 13:07:00| Climate Ark Climate Change & Global Warming Newsfeed

Newsmax: Climate scientists at two U.S. universities said the most recent U.N. report issued in 2013 on the effects of global warming had missed the real rate at which the ice covering the continent would melt, reported Reuters. That 2-year-old report said the worst case of man-made climate change would mean a sea-level rise of between 52 and 98 cm by 2100. The new study suggests the real rise could be 1.5 meters (5 ft), posing an even greater threat to cities from New York to Shanghai. "This could...

James Hansen: Dangerous Sea Level Rise Will Occur in Decades, Not Centuries

2016-03-23 16:03:00| Climate Ark Climate Change & Global Warming Newsfeed

EcoWatch: Dr. James Hansen, the former NASA scientist who is widely credited with being one of the first to raise concerns about human-caused global warming, is a co-author of a new report predicting that the world will undergo devastating sea level rise within mere decadesnot centuries, as previously thought. The report, published Tuesday in the open-access journal Atmospheric Chemistry and Physics, paints an even bleaker picture of the planets future, positing that continued high fossil fuel emissions...

Sea level rise is accelerating; how much it costs is up to us

2016-03-11 12:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: As humans emit heat-trapping gases into the atmosphere, its causing the Earth to warm. Its also causing the ocean waters to rise. In fact, water rise is one of the clearest signatures of a warming world. The questions we want to answer are, how much will sea levels rise, and how fast? The answers to this have large implications on what societies should do. It isnt just coastal communities that will be affected. While there are approximately 150 million people worldwide that live within 3 feet...
