What are the possibilities and prospects for action on climate change if Barack Obama is reelected?

Real talk: Obama will get very little done on climate or energy domestically, especially if Republicans keep the House, most especially if they win the Senate too. The reasons are drearily familiar: deep polarization, corporate influence, and the 60-vote threshold in the Senate. Unless some large and unanticipated exogenous force knocks the system out of equilibrium, we can expect more of what the first term delivered, which is modest (read: woefully insufficient) progress on efficiency and clean energy.
