World Bank chief says global warming threatens the planet and the poorest

Washington Post: World Bank President Jim Yong Kim on Tuesday said climate change was a "fundamental threat' to global economic development as he called for a major new push to reduce extreme poverty over the next 17 years. The bank is in the middle of an internal debate over how to reshape its role in a world where the major developing nations -- the core "customers' for its loans and programs -- have become increasingly middle class and where states caught in civil war pose an intractable development problem....
Global warming mystery: Are North and South really polar opposites?

Christian Science Monitor: The amount of land in the high Arctic covered by trees and upright shrubs could increase by up to 52 percent by midcentury, warming the region to levels climate scientists had previously not expected to see there until 2100. That's the take-home message from a new study that looks at statistical ties between climate and vegetation types to estimate how the Arctic's landscape could change with global warming. The impact of the vegetation changes on the region's climate not only would be felt at...

Fighting global warming with nanotechnology

GMA: Can you imagine homes and buildings remaining cool with air conditioning, or cars that dont heat up like ovens in open parking lots? Stanford scholars have just come up with a new form of cooling panel that reflects sunlight back into space, thus keeping man-made structures cool even in the daytime. The device, described in a paper published March 5 in Nano Letters, works two ways. As a broadband mirror, it reflects as much sunlight hitting a surface as possible. As a thermal emitter, it radiates...

Global warming means seas freeze more off Antarctica: study
2013-03-31 19:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Global warming is expanding the extent of sea ice around Antarctica in winter in a paradoxical shift caused by cold plumes of summer melt water that re-freeze fast when temperatures drop, a study showed on Sunday. An increasing summer thaw of ice on the edges of Antarctica, twinned with less than expected snowfall on the frozen continent, is also adding slightly to sea level rise in a threat to low-lying areas around the world, it said. Climate scientists have been struggling to explain why sea...

Global warming: Apocalypse perhaps a little later
2013-03-30 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Economist: IT MAY come as a surprise to a walrus wondering where all the Arctics summer sea ice has gone. It could be news to a Staten Islander still coming to terms with what he lost to Hurricane Sandy. But some scientists are arguing that man-made climate change is not quite so bad a threat as it appeared to be a few years ago. They point to various reasons for thinking that the planets climate sensitivity--the amount of warming that can be expected for a doubling in the carbon-dioxide level--may not...
