NASA scientists warn of accelerating sea level rise as ice sheets melt

2015-08-28 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Mashable: As the world's ice sheets melt in response to warming air and ocean temperatures, global sea level is increasing. This is already putting cities from New York to Shanghai at risk of almost routine flooding from even relatively minor storms. The question facing scientists and policy makers is how much sea level rise they need to plan for in the coming decades, and recent findings are concerning. On Wednesday, NASA scientists said they expect several feet of global sea level rise by the end of...

NASA teleconference on sea level change warns of rising oceans

2015-08-28 04:07:00| Climate Ark Climate Change & Global Warming Newsfeed

Gizmag: On Aug. 26, NASA held a media teleconference regarding current predictions on sea level rise, highlighting the risks to coastal populations in low-lying areas, and the inherent problems in creating reliable global models. A panel of experts from NASA's recently-founded Sea Level Change Team tells us that ocean levels are inexorably on the rise, but gaps in our understanding and ability to survey risk regions mean we don't know just how fast the change will take place. "People need to be prepared...

Sea Level Rising Faster Than Expected, NASA Warns

2015-08-27 15:04:00| Climate Ark Climate Change & Global Warming Newsfeed

EcoWatch: New research underway indicates that at least three feet of global sea level rise is near certain, National Aeronautics and Space Administration (NASA) scientists warned Wednesday. Thats the higher range of the one to three feet level of rise the UN Intergovernmental Panel on Climate Change (IPCC) gave in its 2013 assessment. Sea levels have already risen three inches on average since 1992, with some areas experiencing as much as a 9-inch rise. Given what we know now about how the ocean expands...

Climate Guru Hansen Warns of Rapid Sea Level Rise

2015-07-27 02:36:00| Climate Ark Climate Change & Global Warming Newsfeed

Environment News Service: Leading climate scientist and activist James Hansen is warning that the 2 degree Celsius limit to Earths temperature rise agreed by world leaders is highly dangerous. His new research paper shows that sea levels are rising much more quickly that previously believed. An adjunct professor in the Department of Earth and Environmental Sciences at Columbia University, Dr. Hansen is lead author of a paper entitled, Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate...

Does past sea level rise portend future rise from warming?

2015-07-22 15:03:00| Climate Ark Climate Change & Global Warming Newsfeed

Environmental News Network: You may have seen claims in recent weeks that historic records show a global temperature rise could give us sea levels 20 feet higher than the norm. How accurate are these claims, and why is it important that we take this issue seriously? The reports are a result of a University of Florida study that was recently published in the journal Science. The researchers, including lead author Andrea Dutton, wanted to investigate how historically Greenland and Antarctic ice sheets have reacted to global...
