Siberian stalactites point to permafrost thaw

Australian Broadcasting Corporation: Climate change Large regions of the planet's permafrost could be vulnerable to thawing if the average global temperature rises just 1.5 degrees more, a new analysis of stalactites and stalagmites in Siberian caves suggests. With climate projections currently suggesting the global climate could warm by more than 2°C over the next century, the new results highlight concerns about the potential for permafrost thawing to amplify climate change by releasing carbon dioxide and methane into the atmosphere....

Nearing a Tipping Point on Melting Permafrost?
2013-02-21 22:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Nearly a quarter of the Northern Hemisphere's land surface is covered in permanently frozen soil, or permafrost, which is filled with carbon-rich plant debris -- enough to double the amount of heat-trapping carbon in the atmosphere if the permafrost all melted and the organic matter decomposed. According to a paper published Thursday in Science, that melting could come sooner, and be more widespread, than experts previously believed. If global average temperature were to rise another 2.5°F (1.5°C),...

Caves point to thawing of Siberia
2013-02-21 21:17:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Evidence from Siberian caves suggests that a global temperature rise of 1.5 degrees Celsius could see permanently frozen ground thaw over a large area of Siberia, threatening release of carbon from soils, and damage to natural and human environments. A thaw in Siberia's permafrost (ground frozen throughout the year) could release over 1000 giga-tonnes of the greenhouse gases carbon dioxide and methane into the atmosphere, potentially enhancing global warming. The data comes from an international...
