From Andrew Revkin at the NY Times:
“The world has seen some extraordinary winter conditions in both hemispheres over the past year: snow in Johannesburg last June and in Baghdad in January, Arctic sea ice returning with a vengeance after a record retreat last summer, paralyzing blizzards in China, and a sharp drop in the globe’s average temperature.
It is no wonder that some scientists, opinion writers, political operatives and other people who challenge warnings about dangerous human-caused global warming have jumped on this as a teachable moment.
“Earth’s ‘Fever’ Breaks: Global COOLING Currently Under Way,” read a blog post and news release on Wednesday from Marc Morano, the communications director for the Republican minority on the Senate Environment and Public Works Committee.
… More clucking about the cold is likely over the next several days. The Heartland Institute, a public policy research group in Chicago opposed to regulatory approaches to environmental problems, is holding a conference in Times Square on Monday and Tuesday aimed at exploring questions about the cause and dangers of climate change.
The event will convene an array of scientists, economists, statisticians and libertarian commentators holding a dizzying range of views on the changing climate — from those who see a human influence but think it is not dangerous, to others who say global warming is a hoax, the sun’s fault or beneficial. Many attendees say it is the dawn of a new paradigm. But many climate scientists and environmental campaigners say it is the skeptics’ last stand.”
