Over at Grist, Joseph Romm has also been sniffing around Lomborg’s polar bear chapter. Like Daniel Berger at Salon (see Question 11), Romm has also done his homework, reeling off study after study that make mincemeat of Lomborg’s claim. (“Debunking Bjorn Lomborg: Part 1: The great polar bear irony,” September 18, 2007). For example, Romm cites a recent U.S. Geological Survey report on the state of polar bears, which concludes:
“Projected changes in future sea ice conditions, if realized, will result in loss of approximately 2/3 of the world’s current polar bear population by the mid 21st century. Because the observed trajectory of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative.”
