Rising Sea Levels Will Require Adaptation For Generations To Come
2013-07-17 05:46:24

Susan Bowen for redOrbit.com - Your Universe Online Current levels of greenhouse gas emissions will have far-reaching effects, even if the levels decrease in the near future. According to a new study published in the Proceedings of the National Academy of Sciences, the greenhouse gases emitted today will cause the sea level to rise for centuries to come. It is estimated each degree of global warming will raise sea levels by more than two meters. Anders Levermann, lead author of the...

Satellite Data Not Enough Predict Ice Cap Melt
2013-07-15 09:38:00

Brett Smith for redOrbit.com - Your Universe Online New research from a team of European scientists has found there is not enough satellite data to determine the rate of polar ice cap melt very far into the future and warned against using current trends to predict sea level rise that might result from melting glaciers. The ice sheets on Greenland and Antarctica represent the biggest potential contributor to sea level rise. According to a study published last year including data from...

Surface Melt Will Continue To Dominate Greenland Ice-Loss
2013-07-10 15:13:45

Lee Rannals for redOrbit.com - Your Universe Online According to research published in the Journal of Glaciology, surface ice melt will be the dominant process controlling ice-loss from Greenland. Greenland's ice sheet is considered an important potential contributor to future global sea-level rise over the next century or longer. It contains an amount of ice that could lead to a rise of global sea-level by more than 22 feet if it completely melted. Changes in its total mass are caused...

New research by UM bioclimatology Assistant Professor Ashley Ballantyne models the influence of Arctic sea ice on Arctic temperatures during the Pliocene era. His research was published in the Research Highlight section of the July issue of Nature Geoscience. The full paper will be published in Palaeogeography, Palaeoclimatology, Palaeoecology: An International Journal for the Geosciences. Ballantyne and coauthors from Northwestern University, the University of Colorado and the National...

Swamp-Like Water System Revealed Under Antarctica's Thwaites Glacier
2013-07-09 14:43:50

Lee Rannals for redOrbit.com - Your Universe Online While using an innovative radar analysis method to accurately image the sub-glacial water system under West Antarctica's Thwaites Galcier, scientists discovered a swamp-like canal system beneath the ice. The scientists, from The University of Texas at Austin's Institute for Geophysics, reported in the Proceedings of the National Academy of Sciences (PNAS) that the swamp-like canal is several times as large as Florida's Everglades....

First Greenland Test Passed By NASA’s Polar Robotic Ranger
2013-07-08 14:30:21

NASA [ Watch The Video GROVER Passes Tests In Greenland ] Defying 30 mph gusts and temperatures down to minus 22 F, NASA's new polar rover recently demonstrated in Greenland that it could operate completely autonomously in one of Earth's harshest environments. The robot known as GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, was designed by teams of students attending engineering boot camps at Goddard in the summers...

Ghost Lake Found Beneath Antarctica's Ice Sheet
2013-07-03 05:32:53

April Flowers for redOrbit.com - Your Universe Online A vast crater has been found in Antarctica's icy surface by the European Space Agency's (ESA) CryoSat satellite. The crater was formed, scientists believe, when a lake lying under about 2 miles of ice drained suddenly. There are lakes of fresh water trapped without a connection to the ocean, deep below the thick ice sheet that covers Antarctica. Scientists who are trying to understand water transport and ice dynamics beneath the...

Greenland Ice Sheet Had Record Melt In 2012 Due To Jet Stream
2013-06-17 13:50:43

Lee Rannals for redOrbit.com — Your Universe Online According to University of Sheffield research, published in the International Journal of Climatology, unusual Jet Stream changes were behind record surface melt of the Greenland Ice Sheet last summer. The Greenland Ice Sheet (GrIS) experienced a record surface melting in the summer of 2012, with more than 90 percent of the ice-sheet surface melting as of July 11, 2012. That was nearly double the previous record loss seen in 2010,...

Basal Melt Responsible For Antarctic Ice Shelf Loss
2013-06-14 06:20:18

redOrbit Staff & Wire Reports - Your Universe Online The majority of Antarctica´s ice loss is caused by warm ocean waters eating away at the undersides of ice shelves, not the sudden release and breaking away of ice masses from glaciers (a process known as calving), according to new research appearing in Friday´s edition of the journal Science. In what is being called “the first comprehensive survey of all Antarctic ice shelves,” researchers from the University...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
