This article makes some excellent points. I particularly liked this excerpt:
 hyping the event as the “last chance to save the world”, with the result that the public ends up taking it about as seriously as shoppers took the man who spent decades walking up and down Oxford Street with a sandwich board carrying the words “prepare to meet thy doom”. People remember that we only apparently had five years to save the Earth 15 years ago. The fact that we are still here – in spite of carbon emissions that have continued to rise – somewhat undermines the message.
