As the United Nations climate summit in Copenhagen enters its final days, what has it wrought? Brendan Cummings reports from Copenhagen about false solutions and promising directions for halting global warming, including through the regulatory mechanisms of the Clean Air Act, while Patrick Bond talks about the flowering of a new global movement against climate change.

This December, the United Nations will meet in Copenhagen to hash out an agreement on global warming, while activists from around the world will amass to demand more radical responses. South Africa-based scholar Patrick Bond talks about carbon trading, the ecological debt owed to Africa, and why a bad agreement in Copenhagen would be worse than no agreement at all.
