Arctic Ice Darkening Faster Previously Thought
2014-02-19 19:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Sea ice in the Arctic Ocean reflects sunlight, and therefore has a cooling effect on the Earth. However, the recent retreat of sea ice has been underestimated, according to a new study, and the Earth's albedo, or reflectivity, is decreasing at a faster rate than previously thought. The study was conducted by researchers at Scripps Institution of Oceanography at the University of California, San Diego, using data from the Cloud's and Earth's Radiant Energy System (CERES) aboard several NASA satellites....

Warming from Arctic Sea Ice Melting More Dramatic than Thought
2014-02-17 21:25:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Melting Arctic sea ice has contributed considerably more to warming at the top of the world than previously predicted by climate models, according to a new analysis of 30 years of satellite observations. Sea ice helps cool the Arctic by reflecting incoming solar radiation back into space. Because of its light color, sea ice has what is known as high albedo, which is the percentage of solar radiation a surface reflects back to space. Dark ocean water left behind by melting sea ice, on the other...
Underestimated Methane Leaks Make Natural Gas Dirtier Than Previously Thought, Says Study

Forbes: Methane emissions are worse than the conventional wisdom would have you believe, according to a new study by researchers at Stanford University. Methane, which is the primary component of natural gas, is an especially powerful greenhouse gas, packing more than two dozen times as much global warming potential than carbon dioxide. Traditionally, environmental regulators and energy industry groups have estimated methane emissions by multiplying the amount of methane emitted by a specific source...

Canada: Oil sands pollution two to three times higher than thought
2014-02-04 14:40:04| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: The amount of harmful pollutants released in the process of recovering oil from tar sands in western Canada is likely far higher than corporate interests say, university researchers said Monday. Actual levels of polycyclic aromatic hydrocarbon (PAH) emissions into the air may be two to three times higher than estimated, said the findings in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal. The study raises new questions about the accuracy of environmental impact...
