Enter With Caution

I have an essay up at the Bulletin of the Atomic Scientists as part of a roundtable on the subject, "When politicians distort science."  My essay begins, "Here we go again . . ."

Please have a look and please come back here with comments, critique or questions. Along with Robert Socolow and Randy Olson we'll be engaging this roundtable discussion for the next month or so, with new pieces coming out every week.
