Greenberg Update

John Fleck comments:

Re: "Greenberg, Pielke Jr, Mann, Ehrlich and Rahmstorf":
The answer is that Greenberg seems not to have written something for Marshall. They transcribed and published his comments from the round table discussion in which he participated.

That's certainly very different than if Greenberg had accepted a writing assignment from the Marshall Institute, and so I was wrong to attribute any nefarious purposes to him, and I hereby apologize. As should Mann, Ehrlich, and Rahmstorf.
