I HAVE BEEN HERE BEFORE: Rupert Darwall writes in the WSJ (paywalled, sadly) about the parallels between the acid rain scare of the 80s and global warming alarmism today. Here’s his conclusion:

To this day, the zombie science of acid rain lives on at the EPA’s website, which falsely states that acidification of soil, streams and lakes is caused by emissions from power stations. The EPA reckons the annual cost of anti-acid-rain measures in the U.S. will reach $65 billion in 2020, but it no longer claims that the money will prevent ecosystem damage. Now it just claims to be improving public health.

In its approach to the science of global warming, the EPA under current Administrator Scott Pruitt couldn’t offer a greater contrast with the acid-rain coverup perpetrated by the EPA during the late ’80s and early ’90s. Instead of attacking dissident scientists, Mr. Pruitt’s proposal to hold red-team/blue-team appraisals would put dissenters on the same footing as consensus-supporting scientists. This will enable proper debate between both camps to reveal the strengths and weaknesses of the scientific consensus on global warming.

Open debate is as crucial to science as it is to democracy. Capping sulfur-dioxide emissions is an economic pinprick compared with the multitrillion-dollar cost of cutting emissions of carbon dioxide. If people’s way of life is to be forcibly changed in an expensive attempt to decarbonize society, at the very least it should be done with their informed consent.

At the very least.
