I think we know the answer to that. Instead, check out the 127 page technical summary.
(Note that when I entered the ISBN for the Summary (92-9169-121-6) to do this review it did not come up on Amazon. However, the cover and title are the same for both documents.
Climate Change 2007 includes a Summary for Policymakers, FAQs, and a useful glossary. The confidence displayed in this document should convince even the strongest of naysayers that we'll be entering a new climate regime, and fairly rapidly. See especially pages 81-91: 'Robust Findings vs Key Uncertainties'.
Feb. 9 2008--
I just finished Novacek's chapter 'Heat Wave' in TERRA (2007). Here's what this paleontologist had to say about this IPCC Summary, p 314:
"Scientific consensus is now overwhleming. In Feb '07, the IPCC issued the conclusion that global warming is unequivocal and humans are very likely (more than 90% likelihood) to be the cause. Ther last time the IPCC reported in 2001, it assigned a conservative 60% likelihood to warming and stated that the link between human activity and climate change was only 'likely.' Even so, some scientist protested that the IPCC 2007 report was too conservative in its estimates of sea level rise because it discounts the recent disclosures on the melting polar ice caps and sliding glaciers. In years past, many scientists regarded the IPCC results as overextended; now many are saying the opposite."
