Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to climate change, according to a new study involving the University of Colorado at Boulder. The new study showed ice sheets like the Greenland Ice Sheet can respond to such warming on the order of decades rather than the centuries projected by conventional thermal models. Ice flows more readily as...

Weather and climate are easily confused, but they're not the same. JPL atmospheric scientist Eric Fetzer explains the difference and gives his thoughts on climate change. Dr. Eric Fetzer  is a scientist at NASA's Jet Propulsion Laboratory. He works on NASA's AIRS mission, recently named the "best new tool for climate science." Since its launch in 2002, AIRS has made pioneering new greenhouse gas measurements and improved weather forecasts and hurricane predictions. 1. What's the...

Climate models project that the global average temperature will rise about 1°C by the middle of the century, if we continue with business as usual and emit greenhouse gases as we have been. The global average, though, does not tell us anything about what will happen to regional climates, for example rainfall in the western United States or in paradisical islands like Hawai'i. Analyzing global model warming projections in models used by the Intergovernmental Panel on Climate Change, a team...

Large blooms of tiny marine plants flourish in Antarctic waters left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. This remarkable colonization is having a beneficial impact on climate change. As the blooms die back phytoplankton sinks to the...

Will all of the ice on Greenland melt and flow out into the sea, bringing about a colossal rise in ocean levels on Earth, as the global temperature rises? The key concern is how stable the ice cap actually is and new Danish research from the Niels Bohr Institute at the University of Copenhagen can now show the evolution of the ice sheet 11,700 years back in time "“ all the way back to the start of our current warm period. The results are published in the esteemed journal Nature....

Sediment cores show the Arctic has been warmer during the past decade than during any 10-year period in the last 2,000 years, scientists said. The study provides a clear example of how increased greenhouse gases are now changing our climate, said Caspar Ammann of the National Center for Atmospheric Research in Boulder, Colo. Ammann and his team studied sediment cores from lakes, tree rings and ice cores, all of which showed the Arctic has been warming since about 1850 -- the beginning of the...

A leading expert told Chinese state media on Tuesday that global warming could prove devastating for the Tibetan plateau, the world's third-largest store of ice, but it helps farming and tourism, AFP reported. The comment, from Qin Dahe, the former head of the China Meteorological Administration, was the only positive in an otherwise gloomy assessment of the impact that rising temperatures will have on Tibet, The China Daily newspaper reported. Qin, now a researcher with the Chinese Academy...

The Greenland ice sheet is melting faster than expected according to a new study led by a University of Alaska Fairbanks researcher and published in the journal Hydrological Processes. Study results indicate that the ice sheet may be responsible for nearly 25 percent of global sea rise in the past 13 years. The study also shows that seas now are rising by more than 3 millimeters a year--more than 50 percent faster than the average for the 20th century. UAF researcher Sebastian H. Mernild and...

Scientists say that a number of the United States' most populous east coast cities "” including New York and Boston "” could see higher than expected rises in sea levels if Greenland's glacial-melt continues at its current rate. Researchers reported that sea levels on North America's northeast coast could potentially rise by 12 to 20 inches more than other coastal regions if the melting of Greenland's ice sheet continues to accelerate. Because of the tremendous quantity of fresh...

By E.B. FURGURSON III Staff Writer Sea level rise related to global warming likely will inundate land, alter wetlands and devastate wildlife around the Chesapeake Bay region by the end of the century, according to a recent report by the National Wildlife Federation. By the year 2100, a projected 2-foot rise would make the Pasadena peninsula extremely vulnerable to a damaging storm surger, said Patty Glick, National Wildlife Federation senior global warming specialist and lead author...
