Mark Lynas writes the disheartening tale of what happened in Copenhagen, fingering the Chinese for the failure of Copenhagen:
Copenhagen was a disaster. That much is agreed. But the truth about what actually happened is in danger of being lost amid the spin and inevitable mutual recriminations. The truth is this: China wrecked the talks, intentionally humiliated Barack Obama, and insisted on an awful “deal” so western leaders would walk away carrying the blame. How do I know this? Because I was in the room and saw it happen.
There seems no reason to think the Chinese will behave differently in international negotiations in the next few decades.
