By Gerard Wynn15 February 2013 LONDON (Reuters) – Vast uncertainty remains over the causes of melting Arctic sea ice and when it may disappear altogether during the summer, which would have consequences for oil explorers, shipping firms and the fight against climate change. The answer will depend on the balance of natural and manmade causes. […]
By Hannah Hickey 13 February 2013 (University of Washington) – The September 2012 record low in Arctic sea-ice extent was big news, but a missing piece of the puzzle was lurking below the ocean’s surface. What volume of ice floats on Arctic waters? And how does that compare to previous summers? These are difficult but […]
By Becky Oskin, OurAmazingPlanet 1 February 2013 The scene of the crime: The Arctic. The suspect: The Great Arctic Cyclone of August 2012. The victim: The Arctic sea ice, which melted to a record low area last year. “The Great Arctic Cyclone of August 2012″ arose in Siberia on 2 August 2012 and crossed the […]
By dana198130 January 2013 A paper recently published in Global Environmental Change by Brysse, et al., (2012) examined a number of past predictions made by climate scientists, and found that that they have tended to be too conservative in their projections of the impacts of climate change. The authors thus suggest that climate scientists […]
Bremerhaven, 15 January 2013 (AWI) – The Arctic sea ice has not only declined over the past decade but has also become distinctly thinner and younger. Researchers are now observing mainly thin, first-year ice floes which are extensively covered with melt ponds in the summer months where once metre-thick, multi-year ice used to float. Sea […]
By FELICITY BARRINGER31 December 2012 (The New York Times) – The record-setting disappearance of Arctic sea ice this fall was an indication to many climate scientists and ice experts that the pace of climate change was outstripping predictions. Now a new study published this week in the journal Geophysical Research Letters provides a look at […]
By Zac Unger17 December 2012 On January 24, 2004, in the frigid moonscape of an Arctic winter, wildlife biologist Steven Amstrup rode in a helicopter flying low over the ice. Using an infrared heat detector, he hoped to find polar bears in their dens. When the gun recorded a hit, Amstrup circled around for a […]
By Larry O’Hanlon 6 December 2012 This year’s record ice melts in Greenland and the Arctic ocean aren’t flukes, but confirmation that the Arctic is racing ahead into a new and unknown climate state, said top US climate scientists today. The announcement came with the release today of the 2012 Arctic Report Card, which calls […]
Contact: Shaye Wolf, (415) 385-5746, swolf@biologicaldiversity.org 30 October 2012 SAN FRANCISCO (Center for Biological Diversity) – As America copes with the destruction caused by Hurricane Sandy, scientists with the Center for Biological Diversity are urging the Environmental Protection Agency to use the Clean Air Act to take emergency action against climate change. Global warming creates […]
By Michael Marshall21 October 2012 If we have to hack the planet, we could at least do it with some finesse. Some of the problems with geoengineering could be fixed by targeting specific regions of the planet, rather than cooling everywhere equally. A rough modelling study published in Nature Climate Change offers a crude blueprint […]
