Two Arctic Ice Seals Gain Endangered Species Act Protection - Warming Climate a Key Factor
2013-01-02 21:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: Responding to a 2008 petition from the Center for Biological Diversity, the federal government today finalized Endangered Species Act protection for two ice-dependent Arctic seals threatened by melting sea ice and snowpack due to climate change. Ringed seals and bearded seals, found in the waters off Alaska, are the first species since polar bears to be protected primarily because of climate change threats. "Arctic animals face a clear danger of extinction from climate change," said Shaye Wolf,...

Ice sheets of West Antarctica are warming fast
2013-01-02 16:32:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: THE ice sheets of West Antarctica are warming much faster than we thought, suggesting swathes of it could melt and send global sea levels soaring. Climatologists have struggled to work out whether Antarctica is warming, and how quickly, because it has few weather stations and the records from some are incomplete. David Bromwich of Ohio State University in Columbus and his colleagues filled in the gaps for one key station using statistics and data from a climate model. They conclude that temperatures...
Arctic Climate Change: sea ice changes increase light absorption, ocean warming
2013-01-01 18:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Bay Area Indymedia: As multi-year sea ice is replaced with thinner first year sea ice, the properties of the sea ice change to allow more light through to the water beneath increasing ocean warming and more melting of sea ice. The study was conducted by scientists with the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association from the research vessel Polarstern. The scientists used a remotely operated vehicle (ROV) to go under the summer sea ice with spectral radiometers. Light transmittance...

Is Climate Change causing an exponential rate of Ice sheet Mass Loss, sea level rise?
2013-01-01 18:53:00| Climate Ark Climate Change & Global Warming Newsfeed
Bay Area Indymedia: The thesis that Hansen has put forward for several years is that Ice Sheet collapse is a non-linear process: that with the inclusion of amplifying climate feedbacks it is likely to follow an exponential rate of acceleration - a doubling rate. It might be a 10 year doubling time, or less. This will lead to extensive sea level rise, perhaps in the order of 5 metres this century. But accurate data measurements of ice mass loss via laboriously estimating mass input and output has only been available...
