Wags, haven't had time to read the article yet, but thought I would follow up on the last sentence above.
The Wall Street Journal pegs the annual budget of IPCC at around 7 million, with the US supplying less than 1/2 of it.
As far as industry funding in opposition, it far outstrips the spending on the IPCC (which you might have guessed). Sort of makes me question the veracity of the entire article. That funding by just a few notable groups/people is around 40 million/year. Probably much higher as not all industry contributors are noted.

Maybe the confusion comes from the author's lack of understanding of the IPCC. While there is a lot of funded research on climate change by many scientists and organizations, the IPCC does no research itself, but produces reports based on peer reviewed, and non peer reviewed, research from multiple disciplines on the climate issue.
Maybe I should be skeptical about the claims the article is making.
