UPDATE: I've started a List of Global Warming and Climate Change Experts for Media  on DeSmogBlog, this one includes a lot of well-known scientists actively publishing in the scientific fields related to global warming and climate change.
Please drop me a line at: email@example.com  with any additional names you would suggest.
Given the economic crisis we're in that's due in large part to the unrestricted abuse of the "free market" even the most jaded of sorts must now be more than a little wary about the expertise of the so-called "free market" think tanks that abound in the United States.
One such free-market champion, the Heartland Institute has sent out a "Journalist's Guide to Global Warming Experts"  in the hopes that somehow journalists will be fooled into thinking that the list they have been provided is "the nation's leading experts on climate change  and related topics."
Nation's leading experts in global warming?
It's amazing what will pass for an expert these days. Well, at least by the Heartland Institute's standards, which include:
Calvin E. Beisner,  the evangelical organizer who once posed the question regarding AIDS funding:
[but] is it rational to allocate $3.5 billion dollars to fight a disease that is almost 100 percent self-inflicted by people intent on immoral and irrational behavior?"
Sterling H. Burnett , Fox News pundit and think tank fellow, who once compared Al Gore's Inconvenient Truth to films made by Adolf Hitler's chief propagandist, Joseph Goebells:
"You don't go see Joseph Goebbels' films to see the truth about Nazi Germany. You don't want to go see Al Gore's film to see the truth about global warming."
Dennis Avery,  think tank fellow for the Hudson Institute, who once argued that:
".. organic farming would produce more cancer, not less," because, "...it's hard to get kids to eat shabby-looking produce."
Myron Ebbel,  another think tanker working for the oil-friendly Competitive Enterprise Institute (CEI).
Tom Harris,  founder of the now defunct oil-lobby connected Natural Resource Stewardship Project.
These guys are about as expert in the science of global warming as I am in knitting sweaters. At the least, they sure as heck aren't the nation's leading experts.
The list goes on and on and you can check out our comprehensive research database  to cross-reference more names. And if you are media and if you are looking for a comprehensive list of the climate change denial industry, than look no further than the Heartland Institute's guide.
