Europe Hammered By Winter, Is North America Next?
2012-02-18 04:40:38

For the first half of this year's winter, the big news was warm temperatures and lack of snow. Ski resorts were covered in bare dirt, while January temperatures in southern California topped July highs. Then, out of the blue, Europe got clobbered: Over the past two weeks, temperatures in Eastern Europe have nose-dived to -30 degrees Celsius (-22 degrees Fahrenheit). Blizzards and the bone-chilling cold have resulted in the deaths of over 550 people so far, with rooftop-high snow drifts...

Cold Winters May Be Caused By Warmer Summers
2012-01-14 04:15:14

Scientists have offered up a convincing explanation for the harsh winters recently experienced in the Northern Hemisphere; increasing temperatures and melting ice in the Arctic regions creating more snowfall in the autumn months at lower latitudes. Their findings may throw light on specific weather incidents such as the extremely harsh Florida winter of 2010 which ended up killing a host of tropical creatures, as well as the chaos-causing snow that fell on the UK in December 2010....

Extreme Melting On Greenland Ice Sheet Reported
2011-10-26 03:32:48

Glacial Melt Cycle Could Become Self-Amplifying, Making it Difficult to Halt The Greenland ice sheet can experience extreme melting even when temperatures don´t hit record highs, according to a new analysis by Dr. Marco Tedesco, assistant professor in the Department of Earth and Atmospheric Sciences at The City College of New York.  His findings suggest that glaciers could undergo a self-amplifying cycle of melting and warming that would be difficult to halt. “We are...

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...

According to an international report, climate change in the Arctic could raise world sea levels to 5 feet by 2100. A rise like this would threaten the coasts from Bangladesh to Florida, low-lying Pacific islands and cities from London to Shanghai.  It would also raise costs of building tsunami barriers in Japan. "The past six years (until 2010) have been the warmest period ever recorded in the Arctic," according to the Oslo-based Arctic Monitoring and Assessment Programme (AMAP). "In...

Researchers from six countries are in the Arctic studying the potential role that soot, or black carbon, has on the rapidly changing Arctic climate. Although the Arctic is typically viewed as a vast white wasteland, scientists believe a thin layer of soot is causing it to absorb more heat. They want to find out if that is the main reason for the recent rapid warming of the Arctic, which could have an impact on the world's climate for years to come. Black carbon is produced by vehicle...

Researchers and flight crew arrived in Thule, Greenland, on Monday, March 14, for the start of NASA's 2011 Operation IceBridge, an airborne mission to study changes in Arctic polar ice. This year's plans include surveys of Canadian ice caps and expanded international collaboration. The state of Earth's polar ice sheets, glaciers and sea ice is an important indicator of climate change and plays a key role in regulating global climate. With IceBridge, NASA is pushing ahead with its commitment...

Scientists reported on Friday that Greenland's icesheet shed a record amount of melted snow and ice in 2010. The study found that the 2010 runoff was twice the average annual loss in Greenland over the previous three decades, surpassing a record set in 2007. According to the paper, ice melt has now topped this benchmark every year since 1996. Greenland's icesheet could drive up ocean levels by about 23 feet if it melted, drowning coastal cities around the world. No credible projections...

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...
