The Copenhagen climate conference has been a shambles with journalists queing for up to nine hours and still failing to get in.
What was behind the monumental screw-up? A staggering inability to do maths.
The conference centre has a maximum capacity of 15,000, yet NGOs alone were allowed to register 20,000 delegates. That's not counting the 5000 members of the media, nor the 7000 staffers who are running the place, totalling 32,000 before you even get to the people who are meant to be doing the real work here: the negotiators. There were ministers hopelessly waving their diplomatic passes in the queues outside. They weren't let in any faster than anyone else.
