WASHINGTON, June 17, 2012 /PRNewswire-USNewswire/ -- A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected. The climate was suitable to support substantial vegetation -- including stunted trees -- along the edges of the frozen continent.

Eemian Period Is A Poor Analogue For Current Climate Change
2012-06-15 04:34:14

The Eemian interglacial period that began some 125,000 years ago is often used as a model for contemporary climate change. In the international journal “Geophysical Research Letters” scientists from Mainz, Kiel and Potsdam (Germany) now present evidence that the Eemian differed in essential details from modern climatic conditions. Joint press release of the Academy of the Sciences and the Literature Mainz and the GEOMAR | Helmholtz Centre for Ocean Research Kiel. To address...

Derek Walter for redOrbit.com A team of Harvard researchers has developed a superior method for keeping metal surfaces free of ice and frost. It´s a difficult task, but one that could have substantial implications for metal surfaces used in wind turbines, aircraft, refrigeration systems, marine vessels and the construction industry. Airplane wings, railings, and other fabrication parts are just a sample of how often metal is used throughout the world in most of the largest...

[ Watch the Video ] redOrbit Staff & Wire Reports NASA officials announced on Thursday that an expedition they sponsored had uncovered a massive bloom of phytoplankton in the ice-capped waters of the Arctic Ocean -- a discovery which the U.S. space agency has called "as dramatic and unexpected as finding a rainforest in the middle of a desert." The findings, which came as part of Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment (ICESCAPE)...

80-Year-Old Photos Aid In Greenland Ice Melt Study
2012-05-30 09:11:47

Researchers from Denmark´s University of Copenhagen have gained new insight into the loss of ice mass in Greenland´s glaciers thanks to a chance discovery of 80-year-old photo plates discovered in a Danish basement. It is often difficult for scientists to assess the scale and speed of Arctic ice melt, but the extremely rare photos provide them with a more accurate picture. Greenland´s ice was rapidly melting in the 1930s, followed by a cooling period in middle of the 20th...

Using statistical tool, researchers are able to track where the melting that contributes to sea level rise happens It was used to help Apollo astronauts navigate in space, and has since been applied to problems as diverse as economics and weather forecasting, but Harvard scientists are now using a powerful statistical tool to not only track sea level rise over time, but to determine where the water causing the rise is coming from. As described in an April 23 paper in the Proceedings of...

Antarctic Octopus Provides Clues To Ice Sheet Collapse
2012-05-10 08:34:34

Brett Smith for Redorbit.com A joint team of UK and Australian researchers has found that two separate groups of Antarctic octopuses, from the Ross and Weddell seas on different sides of the continent, are almost genetically identical. This suggests that the two seas, which are now separated by the West Antarctic Ice Sheet, were once joined together, possibly a result of the partial collapse of the continental ice sheet. Researchers analyzed the genes of 450 Turquet's octopuses...

Was Little Ice Age Caused By Increased Volcanism In The Middle Ages?
2012-05-10 08:19:09

A large part of the Northern Hemisphere was in the midst of an unusual cold snap for nearly 500 years, from the Middle Ages through the early 19th century, in what scientists now call the “Little Ice Age.” A new study, published in the journal Geophysical Research Letters, has probed the longstanding mystery of when this event actually began, what caused it and how it was sustained for such a long period. Gifford Miller, a climatologist at the University of Colorado at...

Antarctica Ice Sheet May Begin Melting Rapidly By Century's End
2012-05-09 13:58:16

Scientists report in the journal Nature that an Antarctic ice sheet may start to melt rapidly in this century. The finding, made by climate researchers of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, refute a widely believed theory that ice shelves in the Weddell Sea would not be affected by global warming due to the peripheral location of the sea. "The Weddell Sea was not really on the screen because we all thought that unlike the Amundsen...

Deep sediments are unparalleled record of biotic changes over past 200,000+ years University of California, Berkeley, scientists are drilling into ancient sediments at the bottom of Northern California's Clear Lake for clues that could help them better predict how today's plants and animals will adapt to climate change and increasing population. The lake sediments are among the world's oldest, containing records of biological change stretching back as far as 500,000 years. The core...

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...
