Just days before we lost Stephen Schneider, he sat down for this interview with Climate Science Watch director Rick Piltz. Over a thoughtful and poignant conversation, they touch on climate policy, the so-called “experts” who get quoted by the media, and the anti-regulation ideologues with special interests muddying the waters of sound science and policy decisions.

From the transcript:

CSW: Last thoughts to leave us with?

Schneider: The main thing I want people to remember is that when we’re talking about expertise, we’re not talking about expertise in what to do about a problem. That is a social judgment and every person has the same right to their opinion as any person in climate. However, we are talking about the relative likelihood that there could be serious or even dangerous changes. Because before you even decide how you want to deploy resources as a hedge against a wide range of important social problems, you have to know how serious the problems are. All we’re trying to do in science is give the best estimate that honest people with a lot of evidence can, about the relative risks, so they can make wise decisions in their own lives and in who they elect about how we should deal with it.

If you have no idea about the risk, it’s very hard to rationally do risk management. And we feel that there many people deliberately muddying the risk waters because of a combination of ideology and special interest. We have every right to point out that they have weaker credentials in science than those who are convinced on the basis of the forty year record and longer that the scientific community has been successively examining, year after year after year. That is how we make decisions in medical, in health, or in business. We operate on the basis of preponderance of evidence. The same thing must be done for the planetary life support system. That’s why it’s so important to understand who’s credible.

I strongly encourage everyone to watch.
