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...

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...

Ticking Time Bomb: The True Cost Of Arctic Methane Release
2013-07-25 07:44:29

redOrbit Staff & Wire Reports - Your Universe Online An Arctic methane 'time bomb' brought about by rapidly thinning permafrost could cost the world up to $60 Trillion, the size of the entire global economy, a group of economists and polar scientists warned on Tuesday. Methane is a powerful greenhouse gas, although it lasts less than a decade in the atmosphere. Large amounts of the gas are concentrated in the frozen Arctic tundra, and are also found as semi-solid gas hydrates under...

Antarctic Permafrost Melting Faster Than Previously Thought
2013-07-24 17:51:21

Lee Rannals for redOrbit.com - Your Universe Online Scientists reported in the journal Scientific Reports that permafrost in a section of Antarctica is melting faster than expected. Data from Garwood Valley in the McMurdo Dry Valleys region of Antarctica has shown that melt rates accelerated consistently from 2001 to 2012, rising to about ten times the valley's historical average for the present geologic epoch. Scientists previously thought the region's ground ice to be in equilibrium,...

Arctic Permafrost Melts And Releases Greenhouse Gases
2013-06-11 10:18:54

Brett Smith for redOrbit.com - Your Universe Online Conditions within Arctic permafrost soils prevent dead plants and animals from decomposing, resulting in layer upon layer of organic carbon being sequestered just beneath the topsoil. However, rising Arctic temperatures are causing these soils to thaw at unprecedented rates, and NASA scientists are currently looking into just how much greenhouse gas is being released through soil decomposition. Using NASA´s C-23 Sherpa...

Fund recommended to hedge against greatest threat: a breached oil sands tailing pond; Biodiversity in watershed covering roughly 20% of Canada compared to Africa's Serengeti; Alarm raised at melting of permafrost, ice that plays vital global climate role Canada's Mackenzie River basin -- among the world's most important major ecosystems -- is poorly studied, inadequately monitored, and at serious risk due to climate change and resource exploitation, a panel of international scientists warn...

Extreme Arctic Bacteria Could Thrive On Mars
2013-05-24 14:19:27

Lee Rannals for redOrbit.com - Your Universe Online A recent discovery made on Ellesmere Island in the Canadian High Arctic opens up the possibly that bacteria could grow on the surface of Mars. Scientists recently found that a bacterium was able to thrive at five degrees Fahrenheit, which is the coldest temperature ever reported for bacterial growth. The bacterium provides clues about preconditions for microbial life on both the Saturn moon Enceladus and Mars. The researchers...

Researchers Suprised By Arctic Resiliency In Carbon Storage
2013-05-17 08:15:10

April Flowers for redOrbit.com - Your Universe Online Certain assumptions were made by UC Santa Barbara doctoral student Seeta Sistla and her adviser, environmental studies professor Josh Schimel, when they traveled north recently to study the effects of long-term warming on the carbon storage of the Arctic. "We expected that because of the long-term warming, we would have lost carbon stored in the soil to the atmosphere," said Schimel. He explained that the gradual warming would...

Sea-Level Rise Will Overtake One Alaskan Town By 2017

April Flowers for redOrbit.com - Your Universe Online If someone said “climate refuge” to you, what would come to mind? More than likely, the image of someone from a small tropical island in the Pacific, or of a low-lying delta like in Bangladesh — places where residents have been forced out of their homes by sea-level rise. The strict definition of a refugee in international law, according to a report by The Guardian, is rather narrow and typically includes only...
