First, Joe Romm's attacks on me are based solely on his perception of what cause academic research would favor in his own political advocacy. He explained this to me in a comment on Prometheus after I had complained that he was egregiously misrepresenting me and my work:
. . . it doesn’t matter if you can dig up writing of yours from the past (read by hundreds of people) that seems to agree with things I’ve written. What matters is that when the media writes about their interviews with you (for millions of people) they seem to conclude mistaken things — in this case the need for a $20-billion-a-year federal program to “develop new energy technologies."In other words, because Romm disagreed with the policies that I support (somehow making them "mistaken"), he felt justified in attacking my character and misrepresenting my academic work. He explains that what I actually write "doesn't matter." That Machiavellian perspective explains a lot.
Second, and very importantly, we later learned that even as Joe Romm's attacked me and my co-authors of "Dangerous Assumptions" (in Nature, 2008, here in PDF), he lacked a basic understanding of what the paper was about or its methodology. I pointed this out to Romm in an exchange:
It is clear that you still don’t understand the difference between a stabilization scenario and a baseline scenario. . .Romm's response to this comment, which you may remember followed his having already written 10,000 words of attack on our paper, was as revealing as it was remarkable:
Please do explain this “difference between a stabilization scenario and a baseline scenario” and how it matters at all to my central criticism of your conclusion . . .So Romm went on full attack against our paper, which was focused directly on the assumptions used by the IPCC in its baseline and stabilization scenarios, and he didn't even know what the difference was between them! Richard Tol patiently tried to explain to Romm how he had fundamentally misinterpreted the paper (n the comments here) with apparently no success. After that experience, Romm must have realized that he was not really up to debating the substance of policy issues and thereafter refused to engage me. Instead he went on the attack, writing dozens and dozens of posts that slighted me and misrepresented my work, all the while refusing me any opportunity to respond on his blog.
A recent example shows the absurd lengths that Romm will go to to try to smear me. In a recent post he writes:
I apologize for not warning you in advance to put your head in a vise to prevent explosion.
What you fail to realize is that for Roger “climate change” as defined by the IPCC, “global warming” and a “greenhouse gas signal” are obviously and utterly completely different things.
If Joe was trying to make himself look like a fool, he could not do a better job. In fact the three concepts that he mentions are different things. You won't find a single scientist willing to say that these phrases refer to the same concepts. I have even published a peer-reviewed paper on why such concepts matter for policy (here in PDF). But I have learned that discussion (or even mention) of my peer-reviewed research is not a place that Romm is willing to go.
So in the end I have pushed back. I have opened up a thread for the discussion of conclusions from my research and invited Romm (and others employing similar strategies) to "debunk" them. So far, he has been a no show. I'm not surprised.
