I guess it may be technically correct that Lindzen has never conducted "research" for oil and coal interests, but that of course would depend on how you define "research."
Here is what we do know about Lindzen's connections to the fossil fuel industry over the years:
Lindzen charges oil and coal interests $2,500  a day for his consulting services; his 1991 trip to testify before a Senate committee was paid for by Western Fuels, and a speech he wrote, entitled "Global Warming: the Origin and Nature of Alleged Scientific Consensus," was underwritten by OPEC.
Three skeptics—Lindzen, Michaels, and Balling—were hired as expert witnesses  to testify on behalf of Western Fuels Association, a $400 million consortium of coal suppliers and coal-fired utilities.
No mention of this in the Journal News article. Too bad, as it would have changed the context of the entire piece.
