More or Less: Behind the Stats

A four-year bet about global warming between two scientists is settled. In 2008, after there had been no new record for the global average temperature set since 1998, David Whitehouse and James Annan disagreed over whether there would be a new record by 2011. As the UK Meteorological Office publishes the figures for the past year, presenter Tim Harford brings the two scientists together. Who has won, and does the victory tell us anything about global warming? Plus, Peter Stott from the Met Office tells us how the world’s temperature is measured. Also in the programme: sports statistician Robert Mastrodomenico attempts to predict the results of the 2012 Africa Cup of Nations football tournament.
