  • Global temperature for 2010 is expected to be 14.58 °C, the warmest on record.
  • The warmest year on record is 1998, which reached 14.52 °C, was a year dominated by an extreme El Niño
  • Over the ten years, 2000–2009, since the Met Office has issued forecasts of annual global temperature, the mean value of the forecast error is 0.06 °C.
