Uh....John.

I'm sure we can do all those things mentioned....renewables, lower consumption, reduced globalism and the like, but how will any of the modest gains make a hill of beans difference if the planet adds an additional 3 Billions souls over the next 50 years?

Virtually all of the climate change evangelists ignore the single program that could have a massive effect on energy usage - and that is hard core population controls.

Imagine. For the cost of a single windmill with a 20 year life span, perhaps 1,000 woman in Africa could be financially incentived to have their tubes tied....thereby reducing world population by tens of thousands over a few generations. At the same time, a prohibition of all future immigration from 3rd world to 1st world would ensure the 1st world high energy users decrease over time...Look at Japan's results with zero immigration.

Throw in a prohibition on helicopter rides to private islands and we would have this climate problem licked.
