China pledges to halt growth of carbon emissions in climate plan

New York Times: China, the worlds biggest greenhouse gas polluter, pledged on Tuesday to wean its economy away from reliance on fossil fuels as it grows, and to try to bring the rise in its carbon emissions to an earlier end. The Chinese government offered the goals as building blocks for a new international agreement on countering global warming, which governments hope to reach at a conference in Paris late this year. How quickly and how much Chinas emissions will grow is crucial to the arithmetic of global...

US leaves the markets out in the fight against carbon emissions
2015-07-01 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: n 1990, by an overwhelming majority, Congress amended the Clean Air Act to establish a market for electric utilities to trade the right to emit sulfur dioxide, one of the main contributors to acid rain. The law was based on a simple economic insight. If utilities facing high costs to cut emissions could, instead, buy allowances to pollute from those who could cut emissions for less, reducing overall pollution would be much cheaper. The idea had been successfully used before, during the Reagan administration,...

California greenhouse gas emissions fall - but not by much
2015-07-01 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
San Francisco Chronicle: Despite Californias many efforts to fight global warming, the states greenhouse gas emissions rose in 2012, as a nuclear power plant shut down and the drought hit hydroelectric dams hard. But the increase, it turns out, didnt last. Data released by the state on Tuesday show that Californias emissions of carbon dioxide and other heat-trapping gases started falling again in 2013. The drop wasnt much, just 0.3 percent. The states economy still pumped almost 460 million metric tons of greenhouse...

New study reveals mechanism regulating methane emissions in freshwater wetlands
2015-06-30 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Though they occupy a small fraction of Earth's surface, freshwater wetlands are the largest natural source of methane going into the atmosphere. New research from the University of Georgia identifies an unexpected process that acts as a key gatekeeper regulating methane emissions from these freshwater environments. The study, published in Nature Communications by Samantha Joye and colleagues, describes how high rates of anaerobic methane oxidation, a process once considered insignificant in these...

Korea eyes 37 percent emissions cut
2015-06-30 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Korea Herald: South Korea on Tuesday offered to cut its carbon dioxide emissions by 37 percent from the expected business-as-usual level by 2030, revising its previous targets in the face of criticism that the country was backtracking in its progress. The latest target comprises actual mitigations of 25.7 percent of greenhouse gas emissions and the purchase of global carbon credits equivalent to 11.3 percent. This will lead to emissions of 536 million tons of carbon dioxide equivalent, the Environment Ministry...
