Warmer than we thought?

BBC reports on disturbing new findings by the Met Office (the UK's National Weather Service) that the global average temperature could rise by 4°C (7.2°F) by 2060.

The prediction finds variations depending on geographic zone.  For example, it estimates that the temperature in the Arctic could rise by 15°C (27°F) by the end of the century.

The Met Office's projections are based upon an increase in the use of fossil fuels.  Perhaps the dire prediction will assist governments in policymaking and in planning for the Copenhagen Climate Change Conference in December.
