"Stable" Antarctic Permafrost Melting Faster than Expected, Researchers Say
2013-07-24 14:33:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: The stable ice on Antarctic- the coastal permafrost- is melting faster than expected, a new study reported. Researchers said that the melting rate of the coastal Antarctic permafrost is now similar to the melt rate of permafrost at Arctic. The permafrost in Antarctic was considered to be in equilibrium, meaning that it did melt and refreeze, but its mass remained the same. The regions experienced a cooling trend in the past decade and now have stable temperatures. However, researchers have...

Melting Sea Ice Causing Decline in Harp Seal Populations
2013-07-23 01:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Warming temperatures in the North Atlantic Ocean have lead to a decline in sea ice, which is leaving populations of young harp seals dead in the water, according to researchers at Duke University. "Stranding rates for the region's adult seals have generally not gone up as sea ice cover has declined; it's the young-of-the-year animals who are stranding," said David Johnston, a research scientist at Duke's Nicholas School of the Environment, of the pups not even a year old. "And it's not just...
Ice, ice, maybe: Snow and ice melting at record speed
2013-07-20 01:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: You may have noticed its been a hot summer so far. June temperatures were above average across the world, and both NASA and NOAA ranked the month among the top five warmest since record keeping began in the late 1800s. Not surprisingly, snow extent in the Northern Hemisphere was at its third-lowest on record by June. But what makes the current paltry snow cover more significant is the fact that, just a few months ago, the Northern Hemisphere was unusually snowy - April 2013 had the ninth-highest...

Shift in Melting Pattern of the Greenland Ice Sheet Likely to Occur
2013-07-10 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Surface ice melt will become the new form of dominant ice melt in Greenland as outlet glaciers retreat inland, leaving ice production in second place, according to a new study. The Greenland ice sheet is often considered an important potential contributor to future global sea-level rise over the next century or longer: in total, levels would rise by more than 23 feet (seven meters) if it completely melted, scientists estimate. Changes in its total mass are governed by both fluctuations in melting...
