Oh, Thee, of No Little Faith

I don't often read any press release originating from a Ohio State University, but this one was hard to resist:

Antarctic Temperatures Disagree with Climate Model Predictions

COLUMBUS , Ohio – A new report on climate over the world's southernmost continent shows that temperatures during the late 20th century did not climb as had been predicted by many global climate models.

This comes soon after the latest report by the Intergovernmental Panel on Climate Change that strongly supports the conclusion that the Earth's climate as a whole is warming, largely due to human activity.

It also follows a similar finding from last summer by the same research group that showed no increase in precipitation over Antarctica in the last 50 years. Most models predict that both precipitation and temperature will increase over Antarctica with a warming of the planet.

"The best we can say right now is that the climate models are somewhat inconsistent with the evidence that we have for the last 50 years from continental Antarctica.

"We're looking for a small signal that represents the impact of human activity and it is hard to find it at the moment," he [David Bromwich, professor of atmospheric sciences in the Department of Geography, and researcher with the Byrd Polar Research Center at Ohio State University] said.

Bromwich said the disagreement between climate model predictions and the snowfall and temperature records doesn't necessarily mean that the models are wrong.

Professor Bromwich is right. The lack of proof doesn't set aside the fact that the debate is already over.
