Antarctic model raises prospect of unstoppable ice collapse
2016-03-31 13:52:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature: Recent studies suggest that the Antarctic ice sheet is much less stable than scientists once thought. Choices that the world makes this century could determine the fate of the massive Antarctic ice sheet. A study published online this week in Nature1 finds that continued growth in greenhouse-gas emissions over the next several decades could trigger an unstoppable collapse of Antarcticas ice -- raising sea levels by more than a metre by 2100 and more than 15 metres by 2500. That is literally...

Study: Antarctic ice may melt faster than expected
2016-03-31 10:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Warmer air, less frigid water and gravity may combine to make parts of Antarctica's western ice sheet melt far faster than scientists had thought, raising sea levels much more than expected by the end of the century, according to a new study. New physics-based computer simulations forecast dramatic increases in melting in the vulnerable western edge of the continent. In a worst case scenario, that could raise sea level in 2100 by 18 to 34 inches (46 to 86 centimeters) more than an international...

Ocean warming threatens stability of Antarctic ice shelves
2016-03-30 15:08:08| Climate Ark Climate Change & Global Warming Newsfeed
Discover: The Getz Ice Shelf extends several miles into the ocean along the western Antarctic coast. The vertical face of the ice shelf is almost 200 feet high and is estimated to extend another 1,000 feet below the ocean surface. This photo was taken from a NASA DC-8 by Ted Scambos, Lead Scientist at the National Snow and Ice Data Center. Note: Thanks to a spring-break getaway, I`m just now catching up to this new research showing that warming ocean waters are threatening the stability of giant, floating...

Japan regulators OK costly ice wall at Fukushima plant
2016-03-30 14:39:50| Energy - Topix.net
Japanese regulators on Wednesday approved the launch of an unprecedented refrigeration structure resembling giant popsicles that would form a huge underground frozen barrier around the wrecked Fukushima nuclear reactor buildings in a desperate bid to contain contaminated water. The plant's operator, Tokyo Electric Power Co., said it planned to turn on the ice wall Thursday, in an attempt to minimize the risk of contaminated water escaping into the water.
Arctic sea ice falls to record low for winter
2016-03-29 10:51:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Home: Arctic sea ice fell to its lowest winter extent in recorded history for a second straight year, according to scientists at the National Snow and Ice Data Center and NASA. Ice cover in the polar region averaged 14.52 million square kilometres (5.607 m sq miles) on March 24, the US science agencies said in a statement on Monday. Arctic sea ice appears to have reached a record low wintertime maximum for 2nd year in a row https://t.co/L2Ki4T2FK9 pic.twitter.com/WUsnLikuh6 -- NASA (@NASA) March...
