Earth’s Ice Sheets More Stable Than Once Thought
2013-05-17 10:44:21

April Flowers for redOrbit.com - Your Universe Online For decades, researchers have used ancient shorelines to predict the stability of today´s largest ice sheets in Greenland and Antarctica. High shoreline markings from three million years ago as Earth was going through a warm period were thought to be evidence of a high sea level due to ice sheet collapse at the time — an assumption that has led many scientists to believe that if the world´s largest ice sheets collapsed...

Melting Glaciers Contributing Significantly To Sea Rise
2013-05-17 09:49:29

April Flowers for redOrbit.com - Your Universe Online Scientists have known for some time that melting glaciers are contributing to the global sea-level rise. However, the amount being contributed by each region of the planet has never before been calculated with the accuracy of a new study led by researchers at the University of Colorado at Boulder and Clark University. Ninety-nine percent of Earth´s land ice is locked up in the Greenland and Antarctica ice sheets. The study,...

Warming In China Four Times Greater Than Previously Thought
2013-05-15 15:31:28

Brett Smith for redOrbit.com - Your Universe Online According to new research in the Proceedings of the National Academy of Sciences (PNAS), average temperatures in central China are 10 to 14 degrees Fahrenheit hotter today than they were during the last Ice Age 20,000 years ago. The authors of the study predict that these findings, which are two to four times greater than previous models have shown, could help researchers build up more precise models of previous climate change patterns...

Climate Change Needed More Than Ever In The Face Of Melting Glaciers
2013-05-14 15:34:35

Lee Rannals for redOrbit.com — Your Universe Online Our world is shrinking, or at least the icy parts of it are. And new studies only pile on to the growing evidence of how climate change is altering the shape of this planet. Scientists presented findings at the Meeting of the Americas in Cancún, Mexico about how the snow and ice covering Mount Everest is retreating. Glaciers on the mountain have shrunk by 13 percent in the last 50 years and the snow line has shifted...

Lake Elgygytgyn
2013-05-10 05:02:04

April Flowers for redOrbit.com - Your Universe Online An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago. "While existing geologic records from the Arctic contain important hints about this time period, what we are presenting is the most continuous archive...

Iceberg Production Modeled For Greenland Glaciers
2013-05-09 05:59:32

April Flowers for redOrbit.com - Your Universe Online Climate change impacts on the surface of the Greenland Ice Sheet have been widely studied. An understanding, however, of the key processes in iceberg production has eluded researchers for a long time. A new study, led by the Universite Libre de Bruxelles, presents a sophisticated computer model that provides fresh insight into the impact of climate change on the production of icebergs by Greenland glaciers. The model also demonstrates...

NASA's Arctic IceBridge Campaign Closes With Much Success
2013-04-30 14:14:59

Lee Rannals for redOrbit.com — Your Universe Online NASA said its Operation IceBridge team has finished up another successful campaign to continue collecting data of Arctic ice measurements. IceBridge was started in 2009 to help continue and expand a dataset started by NASA's Ice, Cloud and Land Elevation Satellite (ICESat) in 2003. During this year's campaign, the team measured sea ice, mapped sub-ice bedrock and gathered data on Greenland's glaciers by flying science missions...

1000-year Antarctic Peninsula climate reconstruction A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. The research, published this week in the journal Nature Geoscience, adds new knowledge to the international effort that is required to understand the causes of environmental change in Antarctica and...

Antarctic Glacial Melt May Be Natural
2013-04-15 11:05:27

Brett Smith for redOrbit.com - Your Universe Online As the debate over climate change continues, so does the publication of studies that support or challenge the notion that human activity is the main driver of rising temperatures. According to a new study in“¯Nature Geoscience, the dramatic thinning of glaciers in Western Antarctica is due to natural variation, and cannot be attributed directly to carbon emissions. "If we could look back at this region of Antarctica in...

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...
