Arctic sunshine cranks up threat from greenhouse gases
2013-02-12 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: IT'S a solar double whammy. Not only does sunlight melt Arctic ice, but it also speeds up the conversion of frozen organic matter into carbon dioxide. The amount of carbon in dead vegetation preserved in the far northern permafrost is estimated to be twice what the atmosphere holds as CO2. Global warming could allow this plant matter to decompose, releasing either CO2 or methane - both greenhouse gases. The extent of the risk remains uncertain because the release mechanisms are not clear. Rose...

Arctic sunshine revs up greenhouse gases
2013-02-12 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
United Press International: Sunlight in the arctic is delivering a double climate blow, researchers say, by both melting ice and speeding up the release of greenhouse gases. Dead vegetation preserved in far northern permafrost under ice is estimated to contain twice as much carbon dioxide as is held by the atmosphere, and global warming could allow this plant matter to decompose, releasing both that CO2 and methane, they say. Rose Cory at the University of North Carolina at Chapel Hill and her colleagues, studying melting...

Fracking seen by EPA as No. 2 emitter of greenhouse gases
2013-02-06 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: Natural gas and oil production is the second-biggest source of U.S. greenhouse gases, the government said, emboldening environmentalists who say tighter measures are needed to curb the emissions from hydraulic fracturing. In its second-annual accounting of emissions that cause global warming from stationary sources, the U.S. Environmental Protection Agency for the first time included oil and natural- gas production. Emissions from drilling, including fracking, and leaks from transmission pipes...

Schindler Elevator Corporation Reduces Greenhouse Gases With New Vehicle Fleet
2013-02-05 12:00:00| pollutiononline News Articles
Continuing its commitment to conducting business activities in harmony with society and the environment, Schindler Elevator Corporation is replacing more than 500 sedans in their North American vehicle fleet with the Toyota Prius Two, a gas-electric hybrid car which is expected to reduce greenhouse gases by 42% over the company’s current sedan fleet

Greenhouse Gases Affect Rainfall Differently Than Natural Global Warming
2013-01-31 19:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: An international group of scientists has shown that global warming from greenhouse gases affects global rainfall patterns differently than global warming from solar heating. Using computer model simulations, the research team showed that global rainfall has increased less over the present-day warming period than during the Medieval Warm Period between 950 and 1250 AD despite the fact that temperatures today are higher than during that time. The findings of this study were published in todays...
