Mann on advocacy and responsibility

by Judith Curry

 “If you see something, say something.”

For background, recall these previous posts on scientists and advocacy.

Michael Mann’s op-ed

Michael Mann has an op-ed in the NYTimes If you see something, say something. Excerpts:

In my view, it is no longer acceptable for scientists to remain on the sidelines. I should know. I had no choice but to enter the fray. I was hounded by elected officials, threatened with violence and more — after a single study I co-wrote a decade and a half ago found that the Northern Hemisphere’s average warmth had no precedent in at least the past 1,000 years.

So what should scientists do? At one end of the spectrum, you have the distinguished former director of the NASA Goddard Institute for Space Studies, James Hansen, who has turned to civil disobedience to underscore the dangers he sees. 

This activist approach has concerned some scientists, even those who have been outspoken on climate change. One of them, Ken Caldeira of the Carnegie Institution for Science, who has argued that “the only ethical path is to stop using the atmosphere as a waste dump for greenhouse gas pollution,” expressed concern about the “presentation of such a prescriptive and value-laden work” in a paper not labeled opinion.

It is not an uncommon view among scientists that we potentially compromise our objectivity if we choose to wade into policy matters or the societal implications of our work. And it would be problematic if our views on policy somehow influenced the way we went about doing our science. But there is nothing inappropriate at all about drawing on our scientific knowledge to speak out about the very real implications of our research.

If scientists choose not to engage in the public debate, we leave a vacuum that will be filled by those whose agenda is one of short-term self-interest. There is a great cost to society if scientists fail to participate in the larger conversation — if we do not do all we can to ensure that the policy debate is informed by an honest assessment of the risks. In fact, it would be an abrogation of our responsibility to society if we remained quiet in the face of such a grave threat.

This is hardly a radical position. Our Department of Homeland Security has urged citizens to report anything dangerous they witness: “If you see something, say something.” How will history judge us if we watch the threat unfold before our eyes, but fail to communicate the urgency of acting to avert potential disaster?
