‘Physicists are modellers too, but lousy modellers’

No flies on Stephen Schneider

By James Dacey

This great quote came on the final morning here at the AAAS conference in San Diego. Stephen Schneider, an environmental scientist at Stanford University, was lashing out at all forms of climate change denial including those physicists who make a sport of pointing out uncertainties in climate models.

Schneider’s point is that when physicists make laws and theories by studying the relationships between pairs of data, they are still modelling – just with much less data.

The main thrust of Schneider’s talk – delivered with a relish that could have garnished the Mexican burger I had last night – was that climate scientists should not shy away from entering the public debate on climate change. “Because I have a Ph.D. is not a reason to “hang up my citizenship at the door” of a public meeting—we too are entitled to personal opinions,” he said.

Schneider believes that the media’s representation of climate science is being increasingly shaped by the scientifically unqualified and “old men” who overstretch their dwindling expertise.
