Bernie DeGroat, University of Michigan Just how much Arctic permafrost will thaw in the future and how fast heat-trapping carbon dioxide will be released from those warming soils is a topic of lively debate among climate scientists. To answer those questions, scientists need to understand the mechanisms that control the conversion of organic soil carbon into carbon dioxide gas. Until now, researchers believed that bacteria were largely responsible. But in a study published in Science...

Permafrost Thawing Could Accelerate Global Warming
2014-04-08 15:41:51

Kathleen Haughney, Florida State University A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends. The research is featured in the newest edition of the Proceedings of the National Academy of Sciences. “We’ve known for a while now that permafrost is thawing,” said Suzanne Hodgkins, the lead author on the paper...

Climate New research findings from the Centre for Permafrost (CENPERM) at the Department of Geosciences and Natural Resource Management, University of Copenhagen, document that permafrost during thawing may result in a substantial release of carbon dioxide into the atmosphere and that the future water content in the soil is crucial to predict the effect of permafrost thawing. The findings may lead to more accurate climate models in the future. The permafrost is thawing and thus...

Siberia Could Experience Widespread Permafrost Thaw Due To Global Warming
2013-02-23 09:07:48

Lee Rannals for redOrbit.com — Your Universe Online More evidence is pointing to the nightmare scenario that global warming is taking a toll on our planet. Oxford University scientists say that a global temperature rise of 2.7 degrees Fahrenheit could thaw the ground over a large area of Siberia, threatening the release of carbon from soil. If the thawing of Siberia's permafrost occurs, it could see that over 1,000 gigatons of the greenhouse gases carbon dioxide and methane are...

GI Researcher Co-author Of Report On International Permafrost
2012-11-28 09:25:17

University of Alaska Fairbanks University of Alaska Fairbanks researcher Vladimir Romanovsky is one of four scientists who authored a report released today by the United Nations Environmental Programme. The report, "Policy Implications of Warming Permafrost," seeks to highlight the potential hazards of carbon dioxide and methane emissions from warming permafrost, which have not thus far been included in climate-prediction modeling. The report notes that permafrost covers almost a...
