Much can be said about this conference, and I'm sure plenty will be over the next few days. For the moment, I will confine myself to this quote and link:
"To see Obama backtracking on the commitments made by Bush the elder 20 years ago is to see the extent to which a tiny group of plutocrats has asserted its grip on policy."
- George Monbiot, Rio 2012: it's a make-or-break summit.
Just like they told us at Rio 1992.
