    2007 to be 'warmest on record'

    Trees in Australia are parched by the sun in December,2006.

     

    The world is likely to experience the warmest year on record in 2007, the UK's Met Office has forecast.

    An extended warming period, resulting from an El Nino weather event in the Pacific Ocean, is likely to push up global temperatures, experts predict.

     

    They say there is a 60% chance that the average surface temperature will exceed the current record from 1998.

     

    The forecasters also revealed that 2006 saw the highest average temperature in the UK since records began in 1914.

     

    The global surface temperature is projected to be 0.54C above the long-term average of 14C, beating the current record of 0.52C, which was set in 1998.

     

    The annual projection was compiled by the UK Met Office's Hadley Centre, in conjunction with the University of East Anglia.

     

    Chris Folland, head of the Hadley Centre's climate variability research, said the forecast was primarily based on two factors.

     

    The first was greenhouse gas emissions from human activity, he said.

     

    "Greenhouse gases cause heating, while aerosols cause cooling," Professor Folland said.

     

    "The other factor which allows us to make a forecast that whether one year is significantly different from the next is the effect of the El Nino."
