Antarctica Shows Little Sign of Global Warming, Study Shows [This debunks the climate model used for the Global Warming argument.] usinfo.state.gov Scientists' findings viewed as puzzling in light of global trend Scientists report that temperatures on the Antarctic continent have fallen steadily for more than two decades despite an average increase in air temperature experienced by the rest of the planet. According to a January 13 press release, researchers with the National Science Foundation's Long-Term Ecological Research (LTER) site in Antarctica's Dry Valleys adjacent to McMurdo Sound have found that the seasonally averaged surface air temperature has dropped by 0.7 degrees Celsius per decade since the 1980s. They have observed similar downward trends across the rest of the continent since 1978, confirming a continental cooling trend. Their paper, published January 13 in the online version of the journal Nature, says the cooling trend occurred despite a global average increase in air temperature of 0.06 degrees Celsius during the 20th century, making Antarctica unique among the Earth's continental landmasses. The scientists report that the latest findings are puzzling because many climate models indicate that the Polar Regions should serve as bellwethers for any global warming trend, responding first and most rapidly to an increase in temperatures. Researcher Peter Doran, lead author of the paper, said the findings of continental cooling across Antarctica present a challenge to climate modelers. "Although some do predict areas of cooling, widespread cooling is a bit of a conundrum that the models need to start to account for," he said.
