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...

Increasing Shrubs Reduce The Positive Climate Contribution Of Peatlands
2012-12-26 05:44:43

Brett Smith for redOrbit.com - Your Universe Online Bogs and mires are important ecosystems that also play an important role the storage of global atmospheric carbon emissions. According to a study in Nature Climate Change, the peat mosses, which are found in boglands and drive the production of peat, are being outcompeted by vascular plants, resulting in bog degradation. In the study, researchers from the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) closely...

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...

Permafrost zones extend over 50% of Canada's land area. Warming or thawing of permafrost due to climate change could significantly impact existing infrastructure and future development in Canada's north. Researchers Jennifer Throop and Antoni Lewkowicz at the University of Ottawa, along with Sharon Smith with the Geological Survey of Canada, have published a new study, part of an upcoming special issue of the Canadian Journal of Earth Sciences (CJES), that provides one of the first summaries...

Satellite are seeing changes in land surfaces in high detail at northern latitudes, indicating thawing permafrost. This releases greenhouse gases into parts of the Arctic, exacerbating the effects of climate change. Permafrost is ground that remains at or below 0°C for at least two consecutive years and usually appears in areas at high latitudes such as Alaska, Siberia and Northern Scandinavia, or at high altitudes like the Andes, Himalayas and the Alps. About half of the...

Image 1 - Global Permafrost Zones Shown In High-res Google Earth Images

Thawing permafrost will have far-reaching ramifications for populated areas, infrastructure and ecosystems. A geographer from the University of Zurich reveals where it is important to confront the issue based on new permafrost maps -- the most precise global maps around. They depict the global distribution of permafrost in high-resolution images and are available on Google Earth. Unstable cable-car and electricity pylons and rock fall — Alpine countries like Switzerland have already...

Melting Permafrost Amplifies Global Warming Effect
2011-12-01 06:15:21

According to a survey published in the November 30 issue of the journal Nature, melting permafrost in the northern climes is releasing large amounts of methane and carbon, amplifying the global warming effect. When permafrost melts, long dormant microbes come alive and break down the organic matter underneath the layers of frozen soil creating methane. Methane gas has 2.5 times the effect on the atmosphere than carbon dioxide, creating a greater warming effect. The survey, led by Edward...

Wetland
2013-04-19 18:19:23

A wetland is an area of land that is saturated with water, either permanently or seasonally, such that it takes on the traits of a distinct ecosystem. First and foremost, the factor that distinguishes the wetlands from other land forms or water bodies is the unique vegetation that has adapted to its characteristic soil conditions. The wetland consists mostly of hydric soil, which is supportive of aquatic plants. The water that is found in wetlands can be saltwater, brackish, or freshwater....

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
