The issue that I have with the folks who advocate anthropogenic climate change is that near as I can tell there is no way to preserve the standard of living on the planet (feed, clothe, power, etc) and end climate change soon enough, the only way to get even a 50% cut of emissions within a decade is effectively managing to reduce the population of the planet by a similar number.

I think we'd be better off figuring out how to cope with climate change and generally reduce our consumption of natural resources, rather than focusing to tightly on one evil (carbon).
