>On the other hand, anthropogenic global warming is a matter of degree.

Yes, few informed people would disagree. The problem, however, is with how the debate is presented to the public. Watching CNN or MSNBC someone would come away with the impression that the debate is between the political conservative position (either wait and see, or it's not a problem), and the IPCC.

In reality, the scientific debate is centered around the IPCC[1], with some scientists being more conservative in future projections, and some being more dire. The scientific uncertainty that you speak of cuts both ways, and could also end up revealing a nightmare scenario of climate feedbacks. See:http://web.mit.edu/newsoffice/2009/roulette-0519.html
