"Global temperatures 'to decrease'"
"Global temperatures for 2008 will be slightly cooler than last year as a result of the cold La Nina current in the Pacific, UN meteorologists have said.
"The World Meteorological Organization's secretary-general, Michel Jarraud, told the BBC it was likely that La Nina would continue into the summer.
"But this year's temperatures would still be way above the average - and we would soon exceed the record year of 1998 because of global warming induced by greenhouse gases."
