Well this hardly needs me to say it, but what a farce. Did it really take thousands of people showing up for two weeks in Copenhagen to decide that we ought to limit future temperature increases to 2C? This could have been done by email. While they were at it why didn't they just agree that all future hurricanes, tornadoes, floods and droughts would be canceled? To make this happen they are adding an appendix of what everyone is agreeing to, which will not be binding and in any event wouldn't get close to limiting emissions enough to meet the temperature goal.
Of course a six year old could have predicted this outcome. Since all these world leaders aren't that stupid they must be incredibly cynical to let this circus continue. Whoever thinks these negotiations are going anywhere doesn't seem to grasp that there is no we. It is not in the interest of any one country or block of countries to do this, so it simply won't get done. They can meet until the cows come home and it still won't get done.
And as an aside where in the world did these payments to developing countries get to be a main topic. I'm sure it is a very nice thing to do, and all those leaders like Mugabe are looking forward to their new cars and airplanes, but in what way does that lower planetary emissions? It sure looks like guilt money to me. And it has the advantage of being something that the leaders of the developed countries could possibly do, probably by just redirecting other aid.
The only way we could possibly limit emissions to the levels needed would be by shutting down trade with the developing nations until they would agree to stringent limits on emissions produced by their exports. Trying to do this would likely destabilize the planet politically, which could lead to war. Read up on the origins of world war two, both in Europe and Asia. Now that everyone has nukes this cure might be worse than the disease, but who knows. In any event I don't think anyone has the stomach for it. Especially since the developed countries probably don't have the will to put up with the economic hardships that would be required to switch off of fossil fuels fast enough anyway.
So the only possible answer is a massive effort in new low carbon energy technology along with figuring out some way to suck all this extra carbon out of the atmosphere. The sooner we realize that "joint self control" is a failed strategy, the sooner we can get on with doing something useful.
