I have a BS in Physics from Johns Hopkins and dropped out of PhD in Applied Math from Stanford. Where did you get your degrees from smarty pants?

The problem isn't heat in the general sense of the word, it's heat trapped in the atmosphere. Heat trapped in the core of the earth isn't a problem at all, for example. Most human generated heat can be absorbed by matter on the surface and has a negligible impact on atmospheric heat. And if you had enough energy and low cost launch to space you could do things like cheaply send solar reflectors into space.
