“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. “That is noteworthy and a confirmation that we know how the system works.”
These models currently predict that as a result of today’s global climate change, Antarctica will warm twice as much as the rest of the planet, though it won’t reach its peak for a couple of hundred years. While the most likely climate change scenario, given business-as-usual greenhouse gas emissions, is a global average increase of 3 degrees Celsius (5 degrees Fahrenheit) by 2100, the Antarctic is predicted to warm eventually by around 6 degrees Celsius (10 degrees Fahrenheit).
The new results, which are the first good calculation of Antarctica’s ice age temperature and the amount of warming since, do rule out a couple of climate models that do not include enough feedback to accurately reproduce the amplified temperature in the polar regions, Cuffey said.
Cuffey and his colleagues, including Gary Clow of the U.S. Geological Survey in Lakewood, Colorado, published their results online last week in the early edition of the Proceedings of the National Academy of Sciences.
