Trees in Australia are

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."

據(jù)英國氣象局預(yù)測，2007年很可能成為有史以來最熱的一年。
據(jù)有關(guān)專家預(yù)測，由太平洋“厄爾尼諾現(xiàn)象”所造成的溫暖期延長可能會(huì)導(dǎo)致全球氣溫升高。
據(jù)估計(jì)，2007年的全球平均溫度超過1998年所創(chuàng)記錄的可能性為60%。
氣象預(yù)報(bào)工作者稱，去年英國的平均溫度已達(dá)到了1914年以來的最高水平。
2007年全球地表溫度預(yù)計(jì)比長期平均值14攝氏度高出0.54攝氏度，將超過1998年創(chuàng)下的0.52攝氏度的紀(jì)錄。
英國氣象局哈德利中心每年都會(huì)聯(lián)合東英格蘭大學(xué)進(jìn)行此項(xiàng)氣象預(yù)測。
哈德利中心氣候變化研究項(xiàng)目的負(fù)責(zé)人克里斯·福蘭德說，這一預(yù)測主要基于兩大因素。
第一個(gè)因素是人類活動(dòng)所排放的溫室氣體。
福蘭德教授說：“溫室氣體會(huì)使地球升溫，而大氣中的懸浮微粒則能起到降溫效果。”
"另一個(gè)因素是‘厄爾尼諾’效應(yīng)，我們可以據(jù)此預(yù)測下一年的氣候是否會(huì)出現(xiàn)異常。“
