Nitrogen has key role in estimating CO2 emissions from land use change
2013-04-19 22:59:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A new global-scale modeling study that takes into account nitrogen -- a key nutrient for plants -- estimates that carbon emissions from human activities on land were 40 percent higher in the 1990s than in studies that did not account for nitrogen. Researchers at the University of Illinois at Urbana-Champaign and the University of Bristol Cabot Institute published their findings in the journal Global Change Biology. The findings will be a part of the upcoming Fifth Assessment Report from the Intergovernmental...

Bloomberg: Chevron Corp. (CVX) helped write the first-in-the-nation rule ordering reduced carbon emissions from cars and trucks. Its biofuels chief spoke at the ceremony where California Governor Arnold Schwarzenegger signed the executive order in 2007, the same year the oil company pledged to develop a gasoline replacement from wood. Now Chevron is leading a lobbying and public relations campaign to undercut the California mandate aimed at curbing global warming, two years after the state started phasing...

Brazil soya and beef exports driving 30% of deforestation emissions
2013-04-19 04:25:00| Climate Ark Climate Change & Global Warming Newsfeed
RTCC: Beef and soya products from Brazil accounted for a third of carbon emissions associated with deforestation between 1990-2010, scientists say. They warn that the UN`s Reducing Emissions from Deforestation and Forest Degradation (REDD+) initiative and bilateral programmes aimed at preserving the Amazon could be helpless in the face of rising demand for two of the country`s major exports. The study, published in Environmental Research Letters, calls for a greater focus on the role international...

Rise in U.S. Gas Production Fuels Unexpected Plunge in Emissions
2013-04-18 22:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Wall Street Journal: U.S. carbon-dioxide emissions have fallen dramatically in recent years, in large part because the country is making more electricity with natural gas instead of coal. Energy-related emissions of carbon dioxide, the greenhouse gas that is widely believed to contribute to global warming, have fallen 12% between 2005 and 2012 and are at their lowest level since 1994, according to a recent estimate by the Energy Information Administration, the statistical arm of the U.S. Energy Department. While...
