Just to add to Steve’s post below, Der Spiegel makes his point explicitly: dump the U.N. and embrace the process set in place by George W. Bush:

The United Nations has always maintained that climate protection can only be effective if it’s administered globally — and that the issue cannot be solved by smaller groups like the Major Economies Forum on Energy and Climate. It was actually former US President George W. Bush who initiated this kind of forum but at the time many observers were skeptical that it was Bush’s way of circumventing a broader, more global consensus on climate change. This most recent effort, featuring 16 major economies, was launched by President Obama in April of this year and was meant to augment the UN talks in Copenhagen.
And although UN chief Ban Ki-moon seemed almost euphoric during his concluding statements in Copenhagen and at a press conference, it seemed that almost the opposite emotion would have been more appropriate.
The chaotic Copenhagen summit showed up the UN’s shortcomings more clearly than ever — non-governmental organizations felt that they were shut out, small nations believed they were overlooked and some of the larger nations — and the Chinese in particular — showed exactly how unwilling they were to compromise.
These are all bad omens for next year’s negotiations — and even worse signs for the formulation of any sort of legally binding agreement on climate change by the end of 2010.
