The real climate system appears to be dominated by “negative feedbacks” -- instead of the “positive feedbacks” which are displayed by all twenty computerized climate models utilized by the IPCC.

I predict that in the coming years, there will be a growing realization among the global warming research community that most of the climate change we have observed is natural, and that mankind’s role is relatively minor.

And now my old boss when I was at NASA (as well as James Hansen’s old boss), John Theon, has stated very clearly that he doesn’t believe global warming is manmade…and adding “climate models are useless” for good measure. Even I wouldn’t go quite that far, since I use simple ones in my published research.

Unquestionably, the U.N. Intergovernmental Panel on Climate Change (IPCC) was formed to build the scientific case for humanity being the primary cause of global warming. Such a goal is fundamentally unscientific, as it is hostile to alternative hypotheses for the causes of climate change. The most glaring example of this bias has been the lack of interest on the IPCC’s part in figuring out to what extent climate change is simply the result of natural, internal cycles in the climate system.
