Ralph J. Cicerone, president of the National Academy of Sciences, was back in his old haunt this week, celebrating the 20th anniversary of the University of California, Irvine’s Department of Earth System Science, which he founded. He later served as the university’s chancellor. Dr.
A new map of Antarctica illustrates for the first time how ice moves across the continent. The map reveals huge areas of the continent that have never been charted before and its creators believe it may be a crucial tool in helping researchers understand how a warming climate is changing the continent. Rob Muir reports.
Ice moves. It flows in streams and channels. It creeps and compresses and deforms. We see it best perhaps in glaciers birthing icebergs, frozen rivers emptying into the ocean. Now, for the first time ever, we can see just how much ice moves across the entire Antarctic continent, and the view offers up a few big surprises. This new knowledge could help scientists understand how ice is changing now and how it will change as our climate continues to warm in the future. It will help scientists predict how much sea levels will rise as ice melts in coming decades.

The creation of the digital map was supported by NASA and combines data gathered from 2007 to 2009 by satellites belonging to the Canadian Space Agency, the European Space Agency and the Japan Aerospace Exploration Agency.
Huge rivers of ice that flow into the sea from deep within Antarctica have been mapped for the first time.
The breakthrough could be crucial in tracking future sea levels as part of the battle against climate change, according to the scientists who undertook the study.
A team led by Professor Eric Rignot from the University of California at Irvine produced a 'jigsaw' of the glacial formations using data from European, Japanese and Canadian satellites.
