Durban Deal Breaks New Ground, but May Not Slow Climate Change

After working through Saturday night into yesterday morning, the UN Conference on Climate Change in Durban, South Africa finally reached an agreement. It includes India, China and other developing nations, as well as the developed world. But environmental groups call it an "empty shell." The agreement won't go into effect until 2020 and sets no goals for reducing greenhouse emissions in the meantime. Fiona Harvey is environmental correspondent for the Guardian newspaper in the UK.
