Same old rehashed arguments published to coincide with the IPCC report- most of which are debunked succinctly in Hatrack's link.
Also, a "newer" report from the Fraser Institute (a Canadian "free" market fundamentalist "think" tank)
http://www.fraserinstitute.ca/shared/readmore.asp?sNav=pb&id=886Real Climate took this critical view of it:
"An unofficial, "Independent Summary for Policymakers" (ISPM) of the IPCC Fourth Assessment report has been delivered by the Fraser Institute. It's a long, imposing-looking document, resembling, come to think of it, the formatting of the real Summary for Policymakers (SPM) document that was released on Friday after final negotiations of the IPCC in Paris last week. The Fraser Institute has assembled an awesome team of 10 authors, including such RC favorites as kilter-against-windmills-and-hockey-sticks Ross McKitrick, and other luminaries such as William Kininmonth, MSc, M.Admin -- whose most recent paper is "Don't be Gored into Going Along" in the Oct-Nov issue of Power Engineer.
To be fair, he did publish a paper on weather forecasting, back in 1973. According to the press release, the London kickoff event will be graced by the presence of "noted environmentalist" David Bellamy. It's true he's "noted," but what he's noted for is his blatant fabrication of numbers purporting to show that the world's glaciers are advancing rather retreating, as reported here.
Why go to all the trouble of producing an "independent" summary? The authors illuminate us with this wisdom regarding the official Summary for Policymakers: "A further problem is that the Summary for Policy Makers attached to the IPCC Report is produced, not by the scientific writers and reviewers, but by a process of negotiation among unnamed bureaucratic delegates from sponsoring governments." This statement (charitably) shows that the Fraser Institute authors are profoundly ignorant of the IPCC process.
In fact, the actual authors of the official SPM are virtually all scientists, and are publically acknowleged. Moreover, the lead authors of the individual chapters are represented in the writing process leading to the SPM, and their job is to defend the basic science in their chapters. As lead author Gerald Meehl remarked to one of us on his way to Paris: "Scientists have to be ok, they have the last check. If they think the science is not represented, then they can send it back to the breakout groups. "
