I am a solid state physicist. I feel bad that I know nothing about global warming (in terms of the details: what experiments have been done, what models exist, key papers, what, if any, real controversy there is). What resources would be recommended? What papers, books, websites? It is hard to do this oneself without being deluged with the political aspect of all this, and at a level targeted for a physicist. I apologize if this is an inappropriate forum for this question; no other sub-division seemed most relevant.
