Permafrost carbon release to have similar impact deforestation
2015-04-10 16:49:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: As permafrost soils thaw the greenhouse gases stored are likely to be released gradually and over a prolonged period of time, having a similar affect to topical deforestation, according to research from the US Geological Survey. Permafrost soils contain twice as much carbon as there is currently in the atmosphere. As climate change has an impact and permafrost thaws the release of carbon dioxide and methane into the atmosphere increases. Temperatures in high-latitude regions of the Earth, where...

US carbon pollution set for 2015 drop as coal plants close
2015-04-10 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
RTCC: US efforts to cut greenhouse gas emissions look set for a huge boost this year, with carbon pollution from the power sector set to fall to its lowest level since 1994. Record numbers of US coal-fired power plants are set to close this year, and analysts at Bloomberg New Energy Finance (BNEF) say this will likely see power sector emissions drop 15.4% below 2005 levels. Research published today indicates 23GW, 7% of US coal capacity, will come offline due to a combination of low gas prices, new mercury...
Permafrost Carbon Bomb May Be More of a Slow Burn, Say Scientists
2015-04-09 21:45:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The carbon bomb stored in the thawing Arctic permafrost may be released in a slow leak as global warming takes hold, rather than an eruption, according to new research. Scientists at the US Geological Survey (USGS) found previous predictions of a catastrophic release of carbon dioxide and methane into the atmosphere as permafrost thaws may have been overstated. But the impact on the climate of future permafrost emissions remained significant. More than 1,000bn tonnes of carbon are stored...
Scientists confirm that the Arctic could become a major source of carbon emissions
2015-04-09 01:56:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: As the frozen Arctic soil known as "permafrost" thaws, it could release large amounts of carbon in the form of both carbon dioxide and methane to the atmosphere. And this new source of greenhouse gas emissions could be large enough that it could substantially undermine attempts to cut down on emissions from fossil fuels. Now, an overview of what we know about the permafrost carbon problem has just come out in Nature, written by a group of 17 experts on the matter. In other words, this...
