"The greenhouse effect is extremely doubtful" 
                               (article in the Danish newspaper Politiken, 12th January 1998)

"There is no doubt that mankind has influenced the CO2 content of the atmosphere and is well on his way to double it. But it is still not clear whether this will lead to severe temperature rises."
                               (p. 244 in the Danish book from September 1998, `Verdens Sande Tilstand´)

"I criticise Politiken for claiming that the emission of greenhouse gases has been rising, when the total yearly emission actually has declined by 25 percent since the 1980s."
                               (The Danish newspaper Politiken, December 17th 2000).

"There is no doubt that mankind has influenced and is still increasing atmospheric concentrations of CO2 and that this will influence temperature. Yet, we need to separate hyperbole from realities . . . "
                               (p. 317 in `The Skeptical Environmentalist´ from September 2001)

"That humanity has caused a substantial rise in atmospheric CO2 levels over the past centuries, thereby contributing to global warming, is beyond debate. What is debatable, however, is whether hysteria and headlong spending . . . is the only possible response. "
                               (preface to `Cool It!´ from September 2007)

Global warming is "undoubtedly one of the chief concerns facing the world today" and "a challenge humanity must confront". . . "Investing $100bn annually would mean that we could essentially resolve the climate change problem by the end of this century."
