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...

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found By Daniel Stolte, University of Arizona Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found. The study combined paleoclimate records with computer simulations of...

Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels. Scientists have shown for the first time that the terrain beneath glaciers influences how much glacier melt contributes to fluctuations in sea levels. Researchers say the study will improve their understanding of how ice sheet movements have affected sea...

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...

Application deadline is June 20, 2011; deployments to take place between July 12 and July 19, 2011 The National Science Foundation (NSF) is accepting written requests from professional journalists to report on research--including studies of the ice sheet, climate change and atmospheric chemistry--supported in Greenland by NSF's Office of Polar Programs (OPP). OPP and NSF's Office of Legislative and Public Affairs (OLPA) jointly manage and coordinate media visits to the Polar Regions. NSF...

Scientists from the U.S., U.K. and Australia have used ice-penetrating radar to create the first high- resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland in East Antarctica larger than Texas. The map reveals some of the largest fjords or ice cut channels on Earth, providing important insights into the history of ice in Antarctica. The data will also help computer modelers improve their simulations of the past...

ESA's CryoSat team working on the Greenland ice sheet has been honored with a visit from a Dutch delegation including HRH Prince of Orange. The visit is part of a tour to learn more about climate change in polar regions and consequences for the environment. Prince Willem-Alexander's visit to Greenland was at the invitation of the World Wide Fund for Nature-Netherlands. The delegation included Johan van de Gronden, CEO of WWF-NL, Robbert Dijkgraaf, President of the Royal Dutch Academy of...

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...

According to a new study, melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought. There are bout 30,000 islands within the 550,000-square-mile Canadian Arctic Archipelago.  The study found that between 2004 and 2009, the region lost the equivalent of three-quarters of the water in Lake Erie. Alex Gardner, a research fellow in the Department of Atmospheric, Oceanic and Space Sciences at the University 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...
