Each January the Met Office, in conjunction with the University of East Anglia, issues a forecast of the global surface temperature for the coming year. The forecast takes into account known contributing factors, such as El Niņo and La Niņa, increasing
greenhouse gas concentrations, the cooling influences of industrial aerosol particles, solar effects and natural variations of the oceans.
For 2008 Global temperature is expected to be 0.37 °C above the long-term (1961-1990) average of 14.0 °C, but will be the coolest year since 2000 due to the development of a strong La Niņa in the tropical Pacific Ocean.
