From Kate Sheppard, explaining how the Durban climate conference managed to avoid catastrophe and forge a last-minute agreement:
In the end, it came down to a single turn of phrase: changing "legal outcome" in the earlier draft to "an agreed outcome with legal force under the convention applicable to all parties."
Whatever it takes, I guess. In the end, the Durbanites agreed to "launch a process to develop a protocol, another legal instrument or an agreed outcome with legal force." So that's that. A process will be started. The outcome will be a protocol, or maybe a legal instrument, or maybe an agreed outcome with legal force. Hopefully this outcome will happen by 2015. And then everyone will sign on by 2020.
This doesn't strike me as an especially cheering result, but, as usual, it's better than a complete meltdown, I suppose. For more details, Michael Levi has a fairly discouraging take here ("It is distressing to see how much attention has become devoted to form rather than function") while David Roberts has a slightly more upbeat take here (the agreement may be mostly symbolic, but it's also "a marker and a serious concession").
