World warming despite cool Pacific and Baghdad snow

OSLO (Reuters) - Climate change is still nudging up temperatures in the long term even though the warmest year was back in 1998 and 2008 has begun with unusual weather such as a cool Pacific and Baghdad's first snow in memory, experts said.

"Global warming has not stopped," said Amir Delju, senior scientific coordinator of the World Meteorological Organization's (WMO) climate program.

Last year was among the six warmest years since records began in the 1850s and the British Met Office said last week that 2008 will be the coolest year since 2000, partly because of a La Nina event that cuts water temperatures in the Pacific.

"We are in a minor La Nina period which shows a little cooling in the Pacific Ocean," Delju told Reuters. "The decade from 1998 to 2007 is the warmest on record and the whole trend is still continuing."

This year has started with odd weather including the first snows in Baghdad in memory on Friday and a New Year cold snap in India that killed more than 20 people. Frost hit some areas of Florida last week but orange groves escaped mostly unscathed.

Iraqis welcomed snow as an omen of peace. "It's the first time we've seen snow in Baghdad," said 60-year-old Hassan Zahar. "I looked at the faces of all the people, they were astonished."

Last year, parts of the northern hemisphere were having a record mild winter with even Alpine ski resorts starved of snow.

Delju said climate change, blamed mainly on human emissions of greenhouse gases from burning fossil fuels, would bring bigger swings in the weather alongside a warming trend that will mean more heatwaves, droughts, floods and rising seas
