@blatham,
This is a common mischaracterization of the debate. Al Gore, Michael Mann & co started out with rather wildly exaggerated predictions of rapid warming and even more rapid increases of the rate of warming that simply didn't materialize. More reasoned analysis by a wider group of scientists, now augmented by much improved world wide data (it's still not perfect - the earth has no simple thermometer) has yielded much smaller estimates of expected warming. The problem is complex and the earth's geological history involves cycles of warming and cooling and variations in CO2 levels that sometimes confound presumed cause and effect - there are many other variables involved here. Recent analysis demonstrates that the recent observed changes in earth's temperature correlate better with CO2 concentrations than any other variable studied, but that's where it stands.
The debate today involves the effects of the expected warming (both good and bad) and what to do about it. There's no shortage of BS on either side of this argument. The tradeoffs involve effectiveness in reducing warming, cost and the side effects of proposed "solutions" on the sustained life and welfare of the earth's 7 billion human inhabitants. Current policies involving reducing energy demand and "renewable" wind & solar technologies will not solve the problem without massive adverse effects on humanity, and all that goes with it. Time and expected new technologies are factors that should be considered, along with the often little noticed adverse effects of subsidies for current marginally effective technologies on investment in newer, better ones. The rejection by environmentalists of proven technologies such as nuclear power should also be reevaluated.
Finally we need to face the issue of whether we should seek an authoritarian world-wide solution to such a problem. There is the little detail of human history to consider here. It doesn't provide much encouragement for that prospect, and the faithfulness of signatories to the various conventions already signed is ample proof of that.
Meanwhile folks look for a way to bell the cat, while condemning the skeptical critics..
