Fierce northern winter linked to Arctic sea ice melt
2013-03-26 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: TONY EASTLEY: There's more evidence today of the retreat of sea ice in the Arctic. Satellite pictures reveal the icy expanse reached its maximum size for the year on March the 15th yet the sea ice was the sixth lowest since satellite records began just over 30 years ago. Climate scientists say the ice loss is contributing to the massive snowstorms and bitter weather experienced in North America and Europe. Ashley Hall reports. ASHLEY HALL: It's been a particularly fierce winter and spring...
Big Melt Expected for Canadian Arctic Glaciers
2013-03-07 15:44:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: A fifth of Canada's Arctic Archipelago glaciers may disappear by the end of the century, contributing 1.4 inches (3.5 centimeters) to sea-level rise, new research finds. For the study, published online Thursday (March 7) in the journal Geophysical Research Letters, scientists used computer models to predict how the glaciers would respond to future climate change. The results were not reassuring. "Even if we assume that global warming is not happening quite so fast, it is still highly likely that...

Ice Melt Means Uneven Sea Level Rise Around the World
2013-02-22 17:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Scientists say the sea level rise caused by climate change during the rest of this century will not affect all parts of the world equally, because of the ways sea, land and ice interact. They say parts of the Pacific are likely to see the highest rise. This region is where many low-lying island countries most vulnerable to sea level rise, like the Seychelles, are already struggling. Their peoples will need evacuation if the scientists' high-end predictions are correct. Northern Europe, on the...
1.5C Rise in Temperature Enough to Start Permafrost Melt, Scientists Warn
2013-02-22 06:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: A global temperature rise of 1.5C would be enough to start the melting of permafrost in Siberia, scientists warned on Thursday. Any widespread thaw in Siberia's permanently frozen ground could have severe consequences for climate change. Permafrost covers about 24% of the land surface of the northern hemisphere, and widespread melting could eventually trigger the release of hundreds of gigatonnes of carbon dioxide and methane, which would have a massive warming effect. However, any such melting...

Arctic Ice Melt Disrupts Balance Of Greenhouse Gases
2013-02-20 07:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Last year, so much sea ice in the Arctic had melted away that it beat the prior record amount set in the summer of 2007. By the end of the 2012 summer, the Arctic Ocean had lost about 2.1 million square miles of ice, according to the U.S. National Snow and Ice Data Center (NSIDC) in Colorado. Experts began to predict the kinds of trouble such a speedy and significant melt could have on the earths ecosystems as a whole. Now, one of these effects has already been seen. According to research from...
