This paper argues that in the future the primary focus of policy research and global agreements should be the de-carbonization of economic development. Consequently, instead of treating climate stabilization and economic development as separate and equal, the strategy should be to re-integrate the two global policy goals, in part by separating responsibility (and funding) from action. This will require an approach that goes beyond Kyoto. The paper invokes the example of the Manhattan Project to argue for a massive, globally funded public investment program for the deployment of renewable energy technologies in developing countries. The climate problem -- The challenge of stabilization -- The conventional approach: Separate climate and development -- The development approach.
