The melting of Arctic sea ice may temporarily stabilize, and the ice may even expand, over the coming years, according to new research by scientists at the National Center for Atmospheric Research (NCAR). "As we learn more about climate variability, new and unexpected research results are coming to light," said Sarah Ruth, program director in the Division of Atmospheric and Geospace Sciences, which funds NCAR. "What's needed now are longer-term observations to better understand the effect of...

According to MIT researchers, the most recent global climate report fails to capture the reality of the changing Arctic seascape. The researchers said the most recent global climate report fails to capture trends in Arctic sea-ice thinning and drift, and in some cases substantially underestimates these trends.  The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report estimates that an ice-free Arctic summer by the year 2100. However, Pierre Rampal, a postdoc in...

Danish researchers say the rate of melting in the Arctic sea may be slower than previously thought. A team from the Danish National Research Foundation for Geogenetics at the University of Copenhagen developed a method to measure the variations in the ice several millennia back in time. The scientists based their results on material gathered along the coast of northern Greenland, which experts believe will be the final place summer ice will survive. "Our studies show that there have been...

An analysis of prehistoric "Heinrich events" that happened many thousands of years ago, creating mass discharges of icebergs into the North Atlantic Ocean, make it clear that very small amounts of subsurface warming of water can trigger a rapid collapse of ice shelves. The findings, to be published this week in Proceedings of the National Academy of Sciences, provide historical evidence that warming of water by 3-4 degrees was enough to trigger these huge, episodic discharges of ice from the...

A federal scientist under internal investigation, apparently over a study on polar bear deaths that was cited by Al Gore in "An Inconvenient Truth", went on the offensive Thursday, filing a complaint alleging persecution from within the Interior Department, MSNBC is reporting. Charles Monnett, Anchorage-based scientist with the U.S. Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE), had earlier been questioned by investigators about the study he co-authored and was then...

Bt Jill Sakai, University of Wisconsin-Madison During the last prolonged warm spell on Earth, the oceans were at least four meters "“ and possibly as much as 6.5 meters, or about 20 feet "“ higher than they are now. Where did all that extra water come from? Mainly from melting ice sheets on Greenland and Antarctica, and many scientists, including University of Wisconsin-Madison geoscience assistant professor Anders Carlson, have expected that Greenland was the main culprit. But...

As their icy Arctic habitat melts, polar bear mothers and their cubs are forced to swim long distances, which expose the cubs to higher mortality rates than cubs who do not have to swim as far, a study shows. "Climate change is pulling the sea ice out from under polar bears' feet, forcing some to swim longer distances to find food and habitat," co-author of the study, Geoff York of World Wildlife Fund (WWF), told Reuters. Polar bears are not naturally aquatic creatures. They rely on ice or...

Rising air temperatures in the Arctic region have led to an increase in rainfall and a decrease in snowfall, making the sea ice more susceptible to melting, a new study has revealed. The research was presented today by Dr James Screen from the University of Melbourne at the XXV International Union of Geodesy and Geophysics General Assembly in Melbourne. The Arctic region is warming more rapidly than anywhere else on Earth. Dr Screen of the University's School of Earth Sciences, who led the...

Sea levels could be rising faster than scientists originally believed, thanks to the warming subsurface waters that could cause more rapid melting of ice sheets in Greenland and Antarctica, researchers from the University of Arizona are claiming. In a new study, University of Arizona Assistant Professor of Geosciences Jianjun Yin and colleagues analyzed 19 different climate models under which global warming would accelerate the melting of the world's largest ice sheets over the next two...

2010 one of the two warmest years on record Worldwide, 2010 was one of the two warmest years on record according to the 2010 State of the Climate report, which NOAA released today. The peer-reviewed report, issued in coordination with the American Meteorological Society, was compiled by 368 scientists from 45 countries. It provides a detailed, yearly update on global climate indicators, notable climate events and other climate information from every continent. This year's report tracks 41...

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...
