doubt mongering

A rare background on the players behind the unsurprising but alarming development in the long campaign to discredit the established scientific fact that burning fossil fuels is causing the world to warm.

This latest escalation fits seamlessly into a decades-old pattern of attempts to deny the reality of environmental ills — smoking, acid rain, ozone depletion, and global warming. Similar or even identical claims have been promoted for decades by other free-market think-tanks, including the American Enterprise Institute, the Cato Institute, the Heartland Institute, and, most persistently, the George C. Marshall Institute.

These think tanks all have two things in common: They promote free-market solutions to environmental problems, and all have long been active in challenging the scientific evidence of those problems.
