Dr. Tim Ball, a former climatology professor at the University of Winnipeg, has written a stunning piece on the politics of global warming that have taken place in the IPCC's summaries and reports. His article appeared in yesterday's Canada Free Press.

Unlike procedure used elsewhere, they [the IPCC] produce and release a summary report independently and before the actual technical report is completed. This way the summary gets maximum media attention and becomes the public understanding of what the scientists said. Climate science is made to appear what it is not. Indeed, it is not even what is in their Scientific Report.

The only place where CO2 is causing temperature increase is in the IPCC computer models. In every record of any duration for any time period in the history of the Earth, temperature increase precedes CO2 increase. So an incorrect assumption that a CO2 increase will cause temperature increase is built into the computer models.

A simple single word definition of science is the ability to predict. It is not used by the IPCC, yet they present their work as scientific predictions. Media and the public generally believe the IPCC is making predictions and that is clearly the assumption for government policies. Sadly, members of the IPCC do nothing to dissuade the public from that view. All previous "projections" were wrong. The most recent example is the period from 2000 to 2008. IPCC predicted warming but temperatures went down while CO2 increased. Finally, the IPCC AR4 itself explains why IPCC model projections fail.

"Models continue to have significant limitations, such as in their representation of clouds, which lead to uncertainties in the magnitude and timing, as well as regional details, of predicted climate change." (AR4, Chapter 8. p.600)
