The scientists are saying that we have only a few years left to stop the rise in emissions before making the kind of rapid reductions that would give us the best chance of avoiding dangerous climate change.

This is not over, people everywhere demanded a real deal before the Summit began and they are still demanding it. We can still save hundreds of millions of people from the devastation of a warming world, but it has just become a whole lot harder.
