>>

>>In Spain's 2007 heatwave, people cooled off as best they could

>>This year has been one of the warmest since 1850, despite the cooling

>>influence of La Nina conditions, according to scientists.

>>The UK's Hadley Centre and University of East Anglia conclude that

>>The 11 warmest years in this set have all occurred within the last 13

>>years. For the northern hemisphere alone, 2007 was the second warmest

>>The findings come as the UN climate summit discusses carbon emission cuts.

>>The Hadley Centre's head of climate prediction, Vicky Pope, who is at the

>>Bali talks, said the data " confirmed the need for swift action to combat

>>further rises in global temperatures because of human behaviour. "

>> The La Nina event has taken some of the heat out of what could have

>> been an even warmer year

>>

>>Phil Jones, UEA

>>The data was presented to Bali delegates by Michel Jarraud,

>>secretary-general of the World Meteorological Organization (WMO), which

>>has partially overseen the landmark assessment published during the year

>>by the Intergovernmental Panel on Climate Change (IPCC).

>> " What we are seeing is a confirmation of the warming trend seen by the

>>IPCC reports, " he said.

>>Pacific heights

>>At the beginning of the year, the same group of scientists said 2007 was

>>set to be the warmest on record.

>> " The year began with a weak El Nino... and global temperatures well above

>>the long-term average, " said Phil Jones, director of the Climatic

>>Research Unit at the University of East Anglia (UEA).

>>THE 10 WARMEST YEARS

>>1998: 0.52C (above the 1961-1990 average)

>>2005: 0.48C

>>2003: 0.46C

>>2002: 0.46C

>>2004: 0.43C

>>2006: 0.42C

>>1997: 0.36C

>>1995: 0.28C

>>El Nino/La Nina explained

>> " However, since the end of April, the La Nina event has taken some of the

>>heat out of what could have been an even warmer year. "

>>El Nino and La Nina represent opposite ends of a periodic and natural

>>variation in climatic conditions across the Pacific.

>>El Nino events see above-average ocean temperatures in the central and

>>eastern Pacific, while lower temperatures in the same regions are

>>manifested during La Nina.

>>The 1998 El Nino event, one of the most powerful on record, was largely

>>responsible for that year being the warmest documented since 1850, and

>>warmer than any since.

>>The warmth of the years since 2000 is thought to be driving the thinning

>>of Arctic sea-ice. Scientists forecast this week that the ice could melt

>>entirely during summers by 2013.
