I have read most of the latest IPCC report, but this blog is not the place that level of scholarly discussion. I can add a few more thoughts:

Rajendra Pachauri, head of the IPCC, has admitted that no warming has occurred so far in the 21st Century.

The original IPCC report makes no concrete claims that man has caused global warming. However, the later “interpretations” by UN bureaucrats and media members have made those conclusions.

Problems with the science contained in the IPCC report are numerous:

No observable evidence that CO2 is driving climate change: http://mensnewsdaily.com/2008/04/19/ipcc-challenged-to-recant-global-warming-position/

Accused of destroying and falsifying evidence:

“The Times recalled that in a recent National Center for Policy Analysis study, Kesten Green and J. Scott Armstrong used these principles to audit the climate forecasts in the Fourth Assessment Report. Green and Armstrong found that the IPCC clearly violated 60 of the 127 principles relevant in assessing the IPCC predictions.” http://www.madeinusanews.com/content/view/399/113/

You can trust the UN all you want, but their track record is pretty weak. Oil for food, sex traffic rings, coddling of terrorists, standing by during ethnic cleansing in Rwanda and more.

Further, for the prediction to be correct for 2000-2008, ALL the remaining months would have to be as cold as January 2008, by far the coldest month in this decade so far.

You seem to be quite skeptical of climate predictions based on the difficulty of meteorologists to predict weather. Are you not aware that these are very different fields with very different models?

You ask us to check the credentials of scientists… why not read the original sources rather than just picking those who are most public? Isn’t a peer-reviewed paper with a reproducible model much more authoritative than unverifiable position claims? How have you come to the conclusion that the dozens of models considered in the IPCC reports were wrong — do you just ignore the data and reject the conclusion based solely on the fact that you distrust anything remotely related to the UN?

Global Warming took place between 1918 and 1940, cooling took place for the next 25 years, warming begain agin in 1965 and ended in 1998. We have now been in a period of cooling for the last 10 years. Does that strike you as odd? The expansion of industry and resource usage continued during that entire period.

Virtually all of the predictions that have come from the IPCC and other global warming advocates have been wrong:
