Estimates of global mean surface-temperature for the year ahead
have been requested by the Department
for Environment, Food and Rural Affairs (Defra) as an indicator
of the progress of climate change. The forecasts are produced
by the Met Office using a combination of statistical methods and
coupled ocean-atmosphere general circulation model predictions
of sea temperature in the tropical Pacific.
| Latest forecast (for 2008) |
Global temperature for 2008 is expected to be 0.37 °C above the long-term (1961-1990) average, the coolest year since 2000 when the value was 0.24 °C.
