COP15picThere are around 120 heads of government at the Copenhagen climate talks, so many that it’s hard to keep track of the exact number.

Their presence has been trumpeted as a sign of the world’s commitment to tackling climate change. But in return for showing up, they all want a chance to address the conference – and by extension the world.

To fit all the dignitaries in, organizers have slots limited to five short minutes, which would probably be barely enough to cover their introduction back home.

Even so, the presentations are scheduled to go on long past midnight, and have already been running very late – because of course no one can interrupt or turn off the microphone of a head of state. Venezuela’s Hugo Chavez managed to hold out for 25 minutes.

Meanwhile talks on agreeing the text of a deal have only just got down to work.

So the two live feeds into our media centre televisions, from the conference centre, are now offering up a strange spectacle.
