2011-09-11 04:01:00

  The area covered by Arctic sea ice during the summer reached a new all-time low on Thursday, with the summer sea ice extent falling to 1.64 million square miles (4.24 million square kilometers), scientists from a German university reported on Friday. According to AFP reports on Saturday, the current level is approximately one-half a percent below the previous record low, which dates back to the first satellite observations in 1972. Researchers at the University of Bremen's...

  A new report from the European Space Agency (ESA) shows that sea ice in the Arctic Ocean has receded dramatically during this summer, opening up two new shipping lanes - the Canadian Northwest Passage and Russia´s Northern Sea Route. The summer of 2007 recorded the lowest amount of sea ice since satellite observations began in 1979. That season was hit with unusual weather; skies opened over the central Arctic Ocean and wind patterns pushed warm air into the region,...

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...

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...

A new survey of barrier islands published earlier this spring offers the most thorough assessment to date of the thousands of small islands that hug the coasts of the world's landmasses. The study, led by Matthew Stutz of Meredith College, Raleigh, N.C., and Orrin Pilkey of Duke University, Durham, N.C., offers new insight into how the islands form and evolve over time "“ and how they may fare as the climate changes and sea level rises. The survey is based on a global collection of...

The Antarctic Peninsula has warmed rapidly for the last half-century or more, and recent studies have shown that an adjacent area, continental West Antarctica, has steadily warmed for at least 30 years, but scientists haven't been sure why. New University of Washington research shows that rising sea surface temperatures in the area of the Pacific Ocean along the equator and near the International Date Line drive atmospheric circulation that has caused some of the largest shifts in Antarctic...

The 2011 Arctic sea ice extent maximum that marks the beginning of the melt season appears to be tied for the lowest ever measured by satellites, say scientists at the University of Colorado Boulder's National Snow and Ice Data Center. The CU-Boulder research team believes the lowest annual maximum ice extent of 5,650,000 square miles occurred on March 7. The maximum ice extent was 463,000 square miles below the 1979-2000 average, an area slightly larger than the states of Texas and...

High-Resolution Video, Photos Available Upon Request New York (Vocus/PRWEB) January 20, 2011 New research shows that 2010 set new records for the melting of the Greenland Ice Sheet, expected to be a major contributor to projected sea level rises in coming decades. "This past melt season was exceptional, with melting in some areas stretching up to 50 days longer than average," said Dr. Marco Tedesco, Director of the Cryosphere Processes Laboratory at the City College of New York (CCNY...

WASHINGTON, Jan. 12, 2011 /PRNewswire-USNewswire/ -- Global surface temperatures in 2010 tied 2005 as the warmest on record, according to an analysis released Wednesday by researchers at NASA's Goddard Institute for Space Studies (GISS) in New York. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The two years differed by less than 0.018 degrees Fahrenheit. The difference is smaller than the uncertainty in comparing the temperatures of recent years, putting them into a...

Record-breaking temperatures, extreme drought, stronger hurricanes and record rainfall are among the latest signs of climate change, scientists are warning. Weather patterns could become worse in the future if the world continues on its fossil-fuel consuming course, the scientists told AFP during a conference call Wednesday to discuss the year in global warming. Michael Mann, one of the leading scientists on the conference call, said he had just returned from a trip to Churchill, Manitoba,...
