The American Enterprise Institute (AEI ) is once again offering $10,000 payments to scientists who will comment on climate change - this time in the search for policy options that will open up a "middle ground" in the debate over climate change policy.

This fascinating-if-true development is reported here on the Science and Politics of Global Climate Change Blog.

The Exxon-funded Fraser Institute officially released its Independent Summary for Policy Makers (ISPM) today, confirming that the version leaked here on the DeSmogBlog last week was authentic.

The Institute also announced that it has scheduled an ongoing attack on the report of the Intergovernmental Panel on Climate Change, promising a "Fraser Institute Supplementary Analysis Series" on topics such as "Fundamental Uncertainties in Climate Modelling."

Kenneth Green, the "visiting scholar" who last year offered $10,000 payments to any scientist who was willing to provide an "independent" analysis of the report of the Intergovernmental Panel on Climate Change, was the former Director of the Centre for Studies in Risk and Regulation at The Fraser Institute - which is set to release such an "independent analysis" on Monday.

For those who are attending the London press conference, it might be reasonable to ask if any of the contributors to this report actually received the $10,000 payment.
