Prediction of Rapid Sea Level Rise Wont Change Global Climate Talks
2015-07-21 22:56:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: A bombshell climate study due out this week warns that sea levels may rise a catastrophic 10 feet (3 meters) by the end of this century, rather than the currently predicted 3 feet (.9 meters). But mainstream climate scientists say the report appears speculative and is not in sync with the leading understanding of melting sea ice. As a result, the study is unlikely to change leading scientific consensus or affect the current negotiations on a comprehensive global agreement on climate change. The...
Hansen: Emergency Cooperation Among Nations Needed Prevent Catastrophic Sea Level Rise

EcoWatch: If a new scientific paper is proven accurate, the international target of limiting global temperatures to a 2°C rise this century will not be nearly enough to prevent catastrophic melting of ice sheets that would raise sea levels much higher and much faster than previously thought possible. According to the new study--which has not yet been peer-reviewed, but was written by former NASA scientist James Hansen and 16 other prominent climate researchers--current predictions about the catastrophic...

Sea Level Could Rise at Least 6 Meters
2015-07-09 23:57:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Even if world manages to limit global warming to 2°C -- the target number for current climate negotiations -- sea levels may still rise at least 6 meters (20 feet) above their current heights, radically reshaping the world's coastline and affecting millions in the process. That finding comes from a new paper published on Thursday in Science that shows how high sea levels rose the last time carbon dioxide levels were this high. That was about 3 million years ago, when the globe was about 3-5°F...
Greenland's Draining Lakes Won't Worsen Sea Level Rise?
2015-06-04 19:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Each summer, Greenland's ice sheet - measuring three times the size of Texas - begins to melt. Pockets of melting ice form hundreds of large, supraglacial lakes on the surface of the ice. Many of these lakes drain through cracks and crevasses in the ice sheet, called moulins, creating a liquid layer over which massive chunks of ice can slide. This natural conveyor belt can speed ice toward the coast, where it eventually falls off into the sea. "It's essentially a check on the inner ice starting...
Maps Depict China's Coasts Under Dramatic Sea Level Rise

Yale Environment 360: Roughly 43 percent of China's population lives near the coast a region that is expected to experience dramatically rising sea levels if global warming continues along its current trajectory. What will China's coast look like far in the future if polar ice sheets and glaciers undergo extensive melting? Cartographer Jeffrey Linn has used projections from the Intergovernmental Panel on Climate Change (IPCC) to depict the impact of a 200-foot rise in global sea level. In this map, he shows the potential...
