Simple enough--there is not enough time. Even if we were to stop dumping CO2 into the atmosphere today, the global temperature change will exceed acceptable limits. If we continue with business as usual, substantial parts of the earth will become uninhabitable. Nothing on a global scale can be done in the twenty or thirty years. Collaborative global problem solving does not seem to work.
