AEI's Steven Hayward and Kenneth Green defend their climate policy projects in the Weekly Standard. Here's a taste:

The irony of this story line is that AEI and similar right-leaning groups are more often attacked for supposedly ignoring the scientific "consensus" and promoting only the views of a handful of "skeptics" from the disreputable fringe. Yet in this instance, when we sought the views of leading "mainstream" scientists, our project is said to be an attempt at bribery. In any event, it has never been true that we ignore mainstream science; and anyone who reads AEI publications closely can see that we are not "skeptics" about warming. It is possible to accept the general consensus about the existence of global warming while having valid questions about the extent of warming, the consequences of warming, and the appropriate responses. In particular, one can remain a policy skeptic, which is where we are today, along with nearly all economists.

Of interest to those who have been following this story, Hayward and Green provide some backstory on their letter to Professors Schroeder and North at Texas A&M, and how this became a major story.

North declined our invitation on account of an already full schedule. Schroeder shared our letter with one of his Texas A&M colleagues, atmospheric scientist Andrew Dessler. Dessler posted our complete letter on his blog in late July, along with some critical but largely fair-minded comments, including: "While one might be skeptical that the AEI will give the [IPCC Fourth Assessment Report] a fair hearing, the fact that they have solicited input from a credible and mainstream scientist like Jerry North suggests to me that I should not prejudge their effort."

Dessler's story was linked on another popular environmental blog (www.grist.org), after which someone in the environmental advocacy community (the Washington Post suggests it was Greenpeace and the Public Interest Research Group) picked up the story and tried to plant it, with a sinister spin, somewhere in the media. Several reporters looked into it--including one from a major broadcast network who spent half a day talking with us in November about the substance of our climate views--but reached the conclusion that there was no story here. . . .

They further seek to place the episode in the context of a broader cliamte "inquisition":

The rollout of the IPCC report and the Guardian story attacking us coincide with the climax of what can be aptly described as a climate inquisition intended to stifle debate about climate science and policy. Anyone who does not sign up 100 percent behind the catastrophic scenario is deemed a "climate change denier." Distinguished climatologist Ellen Goodman spelled out the implication in her widely syndicated newspaper column last week: "Let's just say that global warming deniers are now on a par with Holocaust deniers." One environmental writer suggested last fall that there should someday be Nuremberg Trials--or at the very least a South African-style Truth and Reconciliation Commission--for climate skeptics who have blocked the planet's salvation.

Former Vice President Al Gore has proposed that the media stop covering climate skeptics, and Britain's environment minister said that, just as the media should give no platform to terrorists, so they should exclude climate change skeptics from the airwaves and the news pages. Heidi Cullen, star of the Weather Channel, made headlines with a recent call for weather-broadcasters with impure climate opinions to be "decertified" by the American Meteorological Society. Just this week politicians in Oregon and Delaware stepped up calls for the dismissal of their state's official climatologists, George Taylor and David Legates, solely on the grounds of their public dissent from climate orthodoxy. And as we were completing this article, a letter arrived from senators Bernard Sanders, Pat Leahy, Dianne Feinstein, and John Kerry expressing "very serious concerns" about our alleged "attempt to undermine science." Show-trial hearing to follow? Stay tuned.

Desperation is the chief cause for this campaign of intimidation. The Kyoto accords are failing to curtail greenhouse gas emissions in a serious way, and although it is convenient to blame Bush, anyone who follows the Kyoto evasions of the Europeans knows better. The Chinese will soon eclipse the United States as world's largest greenhouse gas emitter, depriving the gas-rationers of one of their favorite sticks for beating up Americans. The economics of steep, near-term emissions cuts are forbidding--though that's one consensus the climate crusaders ignore. Robert Samuelson nailed it in his syndicated column last week: "Don't be fooled. The dirty secret about global warming is this: We have no solution."
