Read here. Well, it would seem Richard Muller and his Berkeley team take the weekly chutzpah honor with their grandiose PR media blitz and speculative claim for their non-peer reviewed literature.
The obvious arrogant and egotistical approach to climate science by Muller et al. is really not needed, nor recommended, for helping the IPCC to climb out of its self-inflicted pit of scientific corruption. Indeed, the Muller-BEST technique of forcing their "science" on the IPCC prior to a proper vetting and the peer reviewed process just adds a new stink to the existing odor of corruption.
Despite the "BEST" science only confirming what everyone accepted (that the world has warmed since the Little Ice Age), their grandiose public relations machinations belie the real objective: to rig/manipulate the IPCC report process via public pressure towards acceptance of the Muller et al. findings in the next IPCC report.
It's as simple and as crass as that. As they say, read the whole thing and make up your own mind of what's really going on.
