We Need a Manhattan Project to Solve Global Warming

According to Robert Samuelson:

Consider a 2006 study from the International Energy Agency. With present policies, it projected that carbon-dioxide emissions (a main greenhouse gas) would more than double by 2050; developing countries would account for almost 70 percent of the increase. The IEA then simulated an aggressive, global program to cut emissions based on the best available technologies: more solar, wind and biomass; more-efficient cars, appliances and buildings; more nuclear. Under this admitted fantasy, global emissions in 2050 would still slightly exceed 2003 levels.

It sounds like we'll need another Manhattan Project to make fossil fuels obsolete. Wait a moment … We had a Manhattan Project that could make fossil fuels obsolete. It was called the Manhattan Project.

By the way, why do these alleged studies persist in minimizing nuclear energy? (I've had earlier criticisms of minimizing nukes here, there, and over yonder.)
