The extent of the sea ice covering the Arctic Ocean has shrunk. According to scientists from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colo., the amount is the smallest size ever observed in the three decades since consistent satellite observations of the polar cap began. NASA and NSIDC scientists will host a media teleconference at 3 p.m. EDT, today, to discuss this new record low for summertime Arctic sea ice cover. The extent of Arctic sea ice...

Himalayan Glacier Behaviour Mapped By New Study
2012-08-24 11:54:19

Glaciers are one of the largest reservoirs of freshwater on our planet, and their melting or growing is one of the best indicators of climate change. However, knowledge of glacier change has been hampered by lack of data, especially for understanding regional behavior. Measurements from satellites have recently provided the first overview mapping of thickness changes of Himalayan glaciers. In a study published in Nature today, scientists assembled new datasets from Earth-observing...

Antarctic Ice Shelf Collapse Has Been Occurring For 600 Years, Manmade Climate Change Is Now Adding To Problem
2012-08-23 10:53:35

Lawrence LeBlond for redOrbit.com - Your Universe Online The Antarctic Peninsula has been continually shrinking for centuries, since long before the Industrial Revolution, according to an international team of researchers. However, rapid warming over the past 100 years has been unusual and, if it continues, the ice shelf could be on par for a complete collapse. Temperatures in the Antarctic Peninsula began rising around 600 years ago, occurring naturally. This was long before manmade...

Arctic Sea Ice Expected To Hit Record Low Soon
2012-08-22 07:46:38

April Flowers for redOrbit.com - Your Universe Online Sea ice in the Arctic Ocean is likely to hit its lowest next week and then keep on shrinking. Scientists at the U.S. National Snow and Ice Data Center say data shows that the sea ice coverage is tracking below the previous record low, set in 2007. Arctic sea ice extent during the first two weeks of August continues to track below the 2007 record low daily ice extents. As of August 13, ice extent is already among the four lowest...

Greenland Summer Ice Melt Breaks Record Month Before Season Ends
2012-08-16 11:14:51

April Flowers for redOrbit.com - Your Universe Online The summer melting season in Greenland usually lasts from June when the first puddles of meltwater appear, to September when temperatures begin to cool again. Melting over the Greenland ice sheet shattered the seasonal record on August 8 this year — a full four weeks before the close of the melting season, reports Marco Tedesco, assistant professor of Earth and atmospheric sciences at The City College of New York. This year,...

Sea Ice Outlook: How Scientists Calculate State Of Sea Ice
2012-08-15 14:22:47

Brett Smith for redOrbit.com - Your Universe Online While the Sea Ice Outlook could be viewed as a non-scientific crowd sourcing on the low point of Arctic sea ice each year, an averaging of the results produces a surprisingly constant result year after year. The U.S. government program, which emerged out of March 2008 climate change workshops in Palisades, NY, asks for regular submissions regarding the expected state of sea ice. The report generated by the program includes predictions...

redOrbit Staff & Wire Reports - Your Universe Online Arctic sea ice is melting away far more rapidly than experts had previously predicted, with more than 215 cubic miles (900 cubic kilometers) worth disappearing from the Arctic Ocean over the past year, according to information obtained by the European Space Agency's CryoSat-2 probe. According to Robin McKie, Science Editor with the UK newspaper The Guardian, that constitutes a 50% higher rate of loss than the majority of...

More Than A Million Years of Climate History Revealed
2012-08-10 13:25:58

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Cambridge Department of Earth Sciences has successfully reconstructed temperature from the deep sea to reveal how global ice volume has varied over the glacial-interglacial cycles of the past 1.5 million years. The study, "Evolution of ocean temperature and ice volume through the Mid-Pleistocene Climate Transition," reported in the journal Science, announces a major breakthrough in understanding...

Greenland's Rapid Ice Sheet Recession Hard To Predict
2012-08-03 13:01:47

Brett Smith for redOrbit.com - Your Universe Online Despite the rapid thaw of the Greenland Ice Sheet, scientists are still far from even being able to predict its disappearance. Recent research conducted by an international team of scientists provided evidence that this is not the first time in modern history that the ice sheet has receded and then stabilized again. Research and news reports surrounding the melting of polar and sub-polar ice often has a doom and gloom tone, but the...

Columbia Plateau
2013-04-19 16:35:47

The Columbia Plateau ecoregion is a Level III ecoregion designed by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington, with little areas over the Washington state border in Idaho. This ecoregion stretches across a wide swath of the Columbia River Basin from the Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canadian border. It incorporates nearly 500 miles of the Columbia River, as well as the lower reaches of major tributaries....

Arctic Ocean
2013-04-18 22:31:23

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Meltwater
2009-07-06 17:15:30

Meltwater is water that is released from melting snow or ice. This includes meltwater from glacial ice and ice shelves over oceans. Meltwater is often produced during volcanic eruptions, and can cause dangerous lahars (landslides of wet volcanic debris). When meltwater pools on the surface rather than draining or flowing away, it forms pools known as melt ponds. Meltwater will often refreeze as the temperature drops. Meltwater can also collect or melt under the ice's surface. Sub-glacial...
