Rising Carbon Dioxide Levels Aided End Of Ice Age
2012-04-05 04:51:25

A new study published in the journal Nature provides evidence that rising carbon dioxide levels brought an end to the last Ice Age. The researchers analyzed prehistoric global warming and found that permafrost released massive amounts of carbon dioxide that was stored in frozen soil in Polar Regions. This resulted in climate change and increased global temperatures and ocean acidifications, ending the Ice Age. Lead author Jeremy Shakun said the key to understanding the role of carbon...

Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

According to a press release from Europe´s Space administration (ESA) part of Antarctica´s ice sheet has increased in height. These findings come from the ESA´s ice-measuring satellite, CryoSat. According to the ESA, these findings not only provide good news from the ice sheets, but also show the effectiveness of their CryoSat missions. According to their website, ESA.int, CryoSat is Europe´s first mission to address the thickness of land and sea ice and how this...

The first day of spring brought record high temperatures across the northern part of the United States, while much of the Southwest was digging out from a record-breaking spring snowstorm. The weather, it seems, has gone topsy-turvy. Are the phenomena related? Are climate changes in one part of the world felt half a world away? To understand the present, scientists look for ways to unlock information about past climate hidden in the fossil record. A team of scientists led by Syracuse...

Image 1 - Global Sea Level Could Rise As Much As 70 Feet In The Future
2012-03-21 04:04:57

Scientists looked back in time - in the geologic record - to see the future Even if humankind manages to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit)--as the Intergovernmental Panel on Climate Change (IPCC) recommends--future generations will likely have to deal with a completely different world. One with sea levels 40 to 70 feet higher than at present, according to research results published this week in the journal Geology. The scientists, led by Kenneth...

Evidence In Bahamas And Bermuda Suggests Increased Rise In Sea Levels
2012-03-15 11:45:55

Scientists are now predicting sea levels will climb another several inches -- or even a few feet -- by the year 2100, according to recent studies. Studying cliffs and ancient reefs on the sub-tropical islands of the Bahamas and Bermuda, scientists are investigating global sea rise and comparing these results against data from more than a century ago. The Bahamas and Bermuda have been attracting fossil hunters for many years. The land on the Bahamas, for example, is built on a foundation...

But projections for increase today still loom large The seas are creeping higher as the planet warms. But how high will they go? Projections for the year 2100 range from inches to several feet, or more. The sub-tropical islands of Bermuda and the Bahamas contain important sites where researchers have gone looking for answers; by pinpointing where shorelines stood on cliffs and reefs there during an extremely warm period 400,000 years ago, they hope to narrow the range of global sea-level...

The Greenland ice sheet is likely to be more vulnerable to global warming than previously thought. The temperature threshold for melting the ice sheet completely is in the range of 0.8 to 3.2 degrees Celsius global warming, with a best estimate of 1.6 degrees above pre-industrial levels, shows a new study by scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Universidad Complutense de Madrid. Today, already 0.8 degrees global warming has been observed. Substantial...

German and Spanish researchers have discovered that the Greenland ice sheet may be more vulnerable to the effects of global climate change than initially thought, and that temperatures may not have to rise much more before it could be lost for good. According to Bloomberg reporter Alex Morales, scientists at the Complutense University in Madrid (UCM) and the Potsdam Institute for Climate Impact Research (PIK) are reporting that the ice sheet could lose its ability to grow if the global...

Sturdy Scandinavian Conifers Survived Ice Age
2012-03-04 05:52:45

[ Watch the Video] Until now, it was presumed that the last glacial period denuded the Scandinavian landscape of trees until a gradual return of milder weather began and melted away the ice cover some 9000 years ago. That perspective is now disproved by research headed by Professor Eske Willerslev from the Centre for GeoGenetics, University of Copenhagen, Denmark, Laura Parducci from the University of Uppsala, Sweden, and Inger Greve Alsos from Tromsø University Museum,...

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...
