Theories for the pause include that deep oceans have taken up more heat with the result that the surface is cooler than expected, that industrial pollution in Asia or clouds are blocking the sun, or that greenhouse gases trap less heat than previously believed.
The change may be a result of an observed decline in heat-trapping water vapor in the high atmosphere, for unknown reasons. It could be a combination of factors or some as yet unknown natural variations, scientists say.
“The climate system is not quite so simple as people thought,” said Bjorn Lomborg, a Danish statistician and author of “The Skeptical Environmentalist” who estimates that moderate warming will be beneficial for crop growth and human health.
“My own confidence in the data has gone down in the past five years,” said Richard Tol, an expert in climate change and professor of economics at the University of Sussex in England.
This article is a bit of a turnabout for Alister Doyle, who has run a series of mostly unquestioning articles promoting AGW in the past. Now if only Seth Borenstein at AP can begin to start questioning, we could see real journalism on display.
