«The result is not a surprise, but if you look at the global climate models that have been used to analyze what the planet looked like 20,000 years ago — the same models used to
predict global warming in the future — they are doing, on average, a very good job reproducing how cold it was in Antarctica,» said first author Kurt Cuffey, a
glaciologist at the University of California, Berkeley, and professor of geography and of earth and planetary sciences.
A better understanding of how and why the Larsen C crack expanded so quickly could help scientists better
predict the future of all Antarctic ice shelves, says Richard Alley, a
glaciologist at Penn State.
«Greenland is probably going to contribute more and faster to sea level rise than
predicted by current models,» said Eric Rignot, a
glaciologist at NASA's Jet Propulsion Laboratory who studied the glacial flow in a paper in Science last year.
The show's title, Augur, plays between the words «augur» — to portend a good or bad outcome of an event or circumstance, to foresee or
predict — and «auger» — a hand tool often used by soil scientists, geologists and
glaciologists to bore holes into the earth.
All of these observations match the response,
predicted in the late 1970s by
glaciologist John Mercer, of the Antarctic to anthropogenic global warming.
Eric Rignot, a
glaciologist at NASA's Jet Propulsion Laboratory, said, «None of this has been
predicted by numerical models, and therefore all projections of the contribution of Greenland to sea level [rise] are way below reality.»
Yao Tandong, a leading Chinese
glaciologist,
predicts that two thirds of China's glaciers could be gone by 2060.
In an article published three years earlier, Russian
glaciologist Vladimir Kotlyakov did in fact
predict a massive decline in the area covered by glaciers, but not until the year 2350.
In retrospect, most oceanographers and
glaciologists find that estimate too low and say it fails to adequately take into account data suggesting that mountain glaciers and Greenland's continental ice will melt more quickly than initially
predicted.....
Another eminent
glaciologist, Aslak Grinsted, of the Centre for Ice and Climate at the University of Copenhagen, says the IPCC did not provide an «explicitly» higher estimate of sea - level rise over the next century «because we do not have models that reliably can
predict how probable a collapse of the Antarctic ice sheet is.
