Is there a consensus on climate change?

I received an interesting comment from Jim Prall in Toronto, Canada, about an ancient post about Sarah Palin and global warming denialism (click here to read it). Thought I’d put it upfront, to give it maximum attention.

Thanks for an interesting post. A couple of commenters have suggested that many reputable scientists dispute the consensus view that human greenhouse emissions are warming the planet, and need to be reduced. My website looks into this question of how many actual scientists working in climate-related fields accept or reject this view.

My results agree quite well with the survey of AGU members last year by Doran and Kendall-Zimmerman: I find fewer than 3% of qualified researchers dispute the mainstream view. I show links to the scientists’ own web pages and to Google Scholar results on what they’ve published and how widely it has been cited. I have sections specifically addressing Solomon’s “The Deniers” and the TV film “The Great Global Warming Swindle” as well.

  1. What’s the difference between today’s global-warming models and medieval astrology? Answer: We know which astrological models were correct. That’s the conclusion of scientist Kanya Kusano in a January report published by the Japan Society of Energy and Resources, an Osaka-based professional scientific association. The paper, recently translated into English by British technology news Web site the Register, argues that medieval astrologers confirmed their theories by testing their predictions against celestial events that actually unfolded. Similarly, today’s climate science is so complex that only time — and a lot more observation — will tell whether what scientists think they know is really correct. Until then, the alarmist findings by the United Nations Intergovernmental Panel on Climate Change are “an unprovable hypothesis,” Mr. Kusano argues. Two of his colleagues on the five-member panel agree.
