Arctic Lakes Soak Up More Greenhouse Gases Than They Emit: Study
2014-07-18 03:19:15

University of Alaska Fairbanks New University of Alaska Fairbanks research indicates that arctic thermokarst lakes stabilize climate change by storing more greenhouse gases than they emit into the atmosphere. Countering a widely-held view that thawing permafrost accelerates atmospheric warming, a study published this week in the scientific journal Nature suggests arctic thermokarst lakes are 'net climate coolers' when observed over longer, millennial, time scales. "Until now, we've...

Siberia Yamal Peninsula
2014-07-17 10:01:06

Joshua Garrett for redOrbit.com - Your Universe Online What could cause an 80 meter hole to form somewhere in northern Siberia? A meteorite strike? Aliens? Cthulhu? Researchers all over the world are scratching their heads over this one, as no one seems to have an answer they are 100 percent sure of. Reported by the Siberian Times, this giant hole of unknown depth appeared rather suddenly in the Yamal Peninsula, which is said to translate as “end of the world,” giving the whole...

Twelvemile Lake permafrost
2014-06-11 06:47:04

April Flowers for redOrbit.com - Your Universe Online Most studies on Arctic permafrost are harbingers of doom. As the sea ice melts, the permafrost is being affected, and releasing large amounts of greenhouse gases such as carbon and methane. These gases will accelerate the process of global warming, creating a vicious cycle. A new study from the US Geological Survey and McGill University, published in Geophysical Research Letters, has revealed a surprise in permafrost research....

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...

Moss Still Lives After 1500 Years Buried In Antarctic Ice
2014-03-17 14:57:18

Brett Smith for redOrbit.com - Your Universe Online British researchers who typically study polar moss samples because they provide indications of past climate conditions have found that Antarctic moss can survive trapped under ice for over 1,500 years. While some plant material has been brought back to life after 20 years of being frozen, only microbes have been shown to be capable of thousand-year feats of revival; that is until now. "These mosses were basically in a very long-term...

Climate Change Sentinels In The Arctic
2014-02-15 04:47:25

Brett Smith for redOrbit.com - Your Universe Online Being particularly sensitive to carbon monoxide and methane, canaries were often used by miners as sentinels to determine if the toxic mine-related gases were building up to dangerous levels. Speaking this week at the annual meeting of the American Association for the Advancement of Science in Chicago, oceanographer Sue Moore said walruses, polar bears and seals can be looked at in much the same way, in that well-being of these Arctic...

Early Warning System Needed In A World With Changing Climates
2013-12-04 12:31:23

Lee Rannals for redOrbit.com - Your Universe Online The National Research Council says that even gradual climate change can have abrupt impacts in human infrastructure and ecosystems if critical thresholds are crossed, so an early warning system needs to be developed now, before its too late. The federal report calls for the development of an early warning system that could help anticipate sudden changes and emerging impacts. "Research has helped us begin to distinguish more imminent...

Arctic Seafloor Releases Double Previous Estimates Of Methane
2013-11-26 07:19:53

University of Alaska Fairbanks The seafloor off the coast of Northern Siberia is releasing more than twice the amount of methane as previously estimated, according to new research results published in the Nov. 24 edition of the journal Nature Geoscience. The East Siberian Arctic Shelf is venting at least 17 teragrams of the methane into the atmosphere each year. A teragram is equal to 1 million tons. “It is now on par with the methane being released from the arctic tundra, which is...

The high cliffs of Eastern Siberia – which mainly consist of permafrost – continue to erode at an ever quickening pace. This is the conclusion which scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research have reached after their evaluation of data and aerial photographs of the coastal regions for the last 40 years. According to the researchers, the reasons for this increasing erosion are rising summer temperatures in the Russian permafrost regions as...

Climate Change Not Improving NOAA Report
2013-08-07 09:43:37

Brett Smith for redOrbit.com - Your Universe Online Last year was one of the hottest twelve months on record, according to a new report from the National Oceanic and Atmospheric Administration (NOAA) that analyzed global temperatures and climate trends. The US government agency's report was assembled by over 380 scientists from 52 countries. In addition to analyzing temperature data, the annual report also gave the status of other global climate indicators and significant weather...
