The New York Times – September 1, 2010
With the publication of his 2001 book, “The Skeptical Environmentalist,” Bjorn Lomborg, a Danish economics professor, became a leading contrarian voice on global warming and a leading opponent of carbon reduction efforts like the Kyoto Protocol.
Mr. Lomborg did not dispute that adding greenhouse gases like carbon dioxide to the atmosphere was warming the climate; rather, he argued that the vast expense of reining in emissions would far outweigh the benefit deferred by the resultant effect on global temperatures.
