----------------
With the advantage of hindsight, it is revealing to review the techniques the skeptics used to mislead and distort the truth in the debate on the CFC-ozone depletion issue.
*Launch a public relations campaign disputing the evidence.
DuPont, which made 1/4 of the world's CFCs, spent millions of dollars running full-page newspaper advertisements defending CFCs in 1975
*Find and pay a respected scientist to argue persuasively against the threat.
CFC industry companies hired the world's largest public relations firm, Hill & Knowlton, who organized a month-long U.S. speaking tour in 1975 for noted British scientist Richard Scorer,
* Use non-peer reviewed scientific publications or industry-funded scientists who don't publish original peer-reviewed scientific work to support your point of view.
* Trumpet discredited scientific studies and myths supporting your point of view as scientific fact.
* Point to the substantial scientific uncertainty, and the certainty of economic loss if immediate action is taken.
etc.
