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...

A team of geoscientists from Southwest Research Institute (SwRI) using newly available remote-sensing technology has achieved unprecedented detail in quantifying subtle, long-period changes in the water levels of shallow lakes and ponds in hard-to-reach Arctic wetlands. Analysis comparing time-lapsed, high-resolution satellite imagery of the Ahnewetut Wetlands in Kobuk Valley National Park, Alaska, revealed an accelerated loss of surface water in shallow thaw lakes and ponds over a recent...

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...

Arctic Permafrost Melt Releasing Carbon Dioxide At Unprecedented Rate
2013-02-12 09:23:50

Lawrence LeBlond for redOrbit.com - Your Universe Online Editor's note (Feb 16): This story earlier reported that thermokarst failures were occurring do to permafrost melt. However, permafrost doesn't melt, it thaws. The changes have been made to this story to reflect that. Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate. This release is being caused by...

Berkeley Lab research could lead to a better understanding of the Arctic ecosystem´s impact on the planet's climate What does pulling a radar-equipped sled across the Arctic tundra have to do with improving our understanding of climate change? It´s part of a new way to explore the little-known world of permafrost soils, which store almost as much carbon as the rest of the world´s soils and about twice as much as is in the atmosphere. The new approach combines several...

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...

Defrosting Permafrost Could Add To Climate Woes
2012-10-30 09:14:35

Brett Smith for redOrbit.com - Your Universe Online As global warming extends its balmy fingers further into the Arctic regions, defrosting permafrost could release up to 44 billion tons of nitrogen and 850 tons of carbon into the atmosphere, according to a new study from the U.S. Geological Survey (USGS). The doubling of atmospheric carbon that would result from such an unprecedented thaw figures to impact ecosystems, the atmosphere, the Earth´s lakes and rivers, the researchers...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
