Modern anti-science was created by the tobacco industry in the 1950s and then used against climate science, often by the same well-experienced think tanks and individuals. Tobacco anti-science is strangely entangled with climate anti-science, as the attached report shows in detail involving Fred Singer's SEPP, Joseph Bast's Heartland, and more.
S. Fred Singer is President of the Science and Environmental Policy Project (SEPP), but has done almost all the work himself for 20 years., including help for tobacco in the early 1990s. Research for Weird Science  sent me on a trek through his and other IRS Form 990s, which unearthed many curiosities of strange governance, fakery and funny finances, all tax-free.
Singer claimed Frederick Seitz as Chairman for two years after his demise and 20 years after a Philip Morris staffer had written in 1989:
“Dr. Seitz is quite elderly and not sufficiently rational to offer advice.”
SEPP’s finances were curious. SEPP paid no salaries, even for Singer’s 60-hour workweeks. Money flowed oddly. Asset trades often exceeded normal income and they accumulated to $1.5M, tax-free. Then one money trail led to Heartland.
Heartland Institute’s Joseph Bast staunchly defended “Joe Camel,” the infamous campaign to addict younger children. Heartland got tobacco funding for many years, along with a Philip Morris Board member.
Whitney Ball’s DONORS TRUST funded a major expansion of Heartland climate anti-science. Singer collected old associates to help write “NonGovernmental International Panel on Climate Change“ (NIPCC) reports, filled with unsupported claims and long-refuted anti-science.
He was helped by Craig Idso, of the Center for the Study of Carbon Dioxide and Global Change (CDCDGC), whose money flows also seem unusual. Robert Ferguson’s Science and Public Policy Institute (SPPI) was a website and a PO Box in a UPS store and he was actually a CSCDGC employee.
Under Jay Lehr and James Taylor, anti-science permeated Heartland’s Environment and Climate News (E&CN) sent mostly to elected officials. Heartland incessantly touted its access and influence with such officials, but its tax forms claimed no lobbying. It ran “fake science” conferences, paying for government staff attendance. It sent money to foreign non-charity advocacy groups, sent anti-science handbooks to school boards and urged parents to complain. It has been criticized in Nature and Science.
Free speech allows people to express opinions, even lie about facts, but tax-free operation is a revocable privilege. Spreading factual untruths and confusion about smoking or climate science is neither research nor education in the public interest.
Read the report, at least the first 21 pages, backed by nearly 200 of detailed backup.
This report was scheduled to be published in a few days, and by astonishing coincidence, just today we see Heartland Institute Exposed . The report was done entirely from public sources, but today's new information is quite consistent and fills some holes. However, the unnamed large Anonymous donor is now seen to be someone hiding behind DONORS TRUST, and some of the smaller ones dedicating funds appear in pp.57-59, with red itemizations. We also see some of the actual payments I had to infer.
03/11/12 CORRECTION: p.58 omitted a DONORS CAPITAL item for 2008: “For media materials $100,000”, which should be added to various subtotals, making them consistent with the $4,610,000 reported on p.57, Fig. H.1.4. H/T to Michael Fisher.
10/25/12 UPDATE: A major revision  has been posted, with much more information on Barre Seid, DONORS TRUST and other funding issues.
