The choice is apparent. Who will pay for this is not. Will is be funded by the .01 percent of the population that own 95% of the wealth or the rest of us? Most likely, the rest of us.

Your scenarios overlook the very real possibility on catastrophic global cooling. The current ice age is not over – we are in probably in a very short inter-glacial period. In the past 2 million years, it has been this warm less 5% of the time. We could be teetering at the edge of rapid onset cooling such as the 1100 to 1850 Little Ice Age. However bad global warming is, global cooling is worse, and much more likely according to the known climate record. In such a case climate intervention could mark things worse. We still do not know what triggers these cooling events, but one is certain to come eventally.

Either way, you don't see Ford and GM rushing to make the electric car. These guys ought to be the ones financing the bulk of the transition.
