Lawrence LeBlond for redOrbit.com - Your Universe Online Two professors with the Intergovernmental Panel on Climate Change (IPCC) have taken on a new approach to assess future sea level rise due to the world’s melting ice sheets. Their study, published this week in Nature Climate Change, is the first of its kind to use structured expert elicitation (EE) along with an approach that mathematically pools other experts’ opinions to gain a clear picture on ice sheet melting. Researchers...
redOrbit Staff & Wire Reports - Your Universe Online A portion of the Antarctic ice sheet is warming nearly twice as quickly as experts had previously believed, which could increase the region's future contribution to rising sea levels, a team of researchers from the Ohio State University (OSU) has discovered. According to BBC News Environmental Correspondent Matt McGrath, the study authors analyzed temperature records from Byrd Station, a scientific outpost in the center of the...
National Science Foundation Drilling-related breakthroughs funded by NSF expected to advance "frontier science" in a variety of disciplines Three very large-scale, National Science Foundation-funded Antarctic science projects--investigating scientifically significant subjects as varied as life in extreme ecosystems, the fate of one of the world's largest ice sheets and the nature of abrupt global climate-change events--have recently each reached important technological milestones that...
NASA Shrinking Arctic sea ice grabbed the world's attention again earlier this year with a new record low minimum. Growing economic activity in the Arctic, such as fishing, mineral exploration and shipping, is emphasizing the need for accurate predictions of how much of the Arctic will be covered by sea ice. Every June, an international research group known as the Study of Environmental Arctic Change (SEARCH) publishes a summary of the expected September Arctic sea ice minimum known as the...
Compares glacial to global warming. Marlborough, MA, (PRWEB) December 13, 2012 “Tale of the Northwest Passage” has been published to YouTube. This third video in a series compares current climate change to changes observed on a glacial scale. It is the second available on YouTube. “These videos were created as a scientific appendix for the hard Science Fiction eBook Time Arc, a cautionary tale of time travel, and a compelling tale of global warming,” said Frank Paine, video...
April Flowers for redOrbit.com - Your Universe Online The West Antarctica ice sheet is melting faster than expected. An international group of oceanographers led by the University of Gothenburg has published new observations in the journal Nature Geoscience that may improve our ability to predict future changes in ice sheet mass. The water levels of the oceans would be affected globally by a reduction of the ice sheets in Antarctica and Greenland, making it problematic that...
Lee Rannals for redOrbit.com - Your Universe Online The 2012 Arctic Report Card was released on Thursday, showing a record low snow coverage and record low sea ice extent. The report card calls on the expertise of 140 scientists from 15 countries to summarize the state of the Arctic. Martin Jeffries of the Office of Naval Research warns that "if we are not already there, we're clearly on the verge of seeing a new Arctic." The report shows a longer growing season with greener...
April Flowers for redOrbit.com - Your Universe Online A new European Space Agency (ESA) study of snow cover observed by satellites reveals record lows in Eurasia for June each year since 2008. Three of the past five years have seen record low cover in North America, as well. Since satellite observations began some 45 years ago, this is the lowest June snow extent on record. Snow cover in June is falling faster than climate models have predicted. It is even disappearing faster than...
April Flowers for redOrbit.com - Your Universe Online In a new study that ends 20 years of uncertainty, an international team of satellite experts have produced the most accurate assessment of ice losses from Antarctica and Greenland to date. Published in the journal Science, the landmark study shows that the melting of the Antarctic and Greenland ice sheets has contributed 11.1 millimeters to global sea levels since 1992, amounting to one fifth of all sea level rise over the survey...
WASHINGTON, Nov. 29, 2012 /PRNewswire-USNewswire/ -- An international team of experts supported by NASA and the European Space Agency (ESA) has combined data from multiple satellites and aircraft to produce the most comprehensive and accurate assessment to date of ice sheet losses in Greenland and Antarctica and their contributions to sea level rise. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) In a landmark study published Thursday in the journal Science, 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....
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 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...
