Global Warming?

Global Temperatures 'to decrease'

By Roger Harrabin BBC News environment analyst

Global temperatures this year will be lower than in 2007 due to the cooling effect of the La Nina current in the Pacific, UN meteorologists have said.

The World Meteorological Organisation's secretary-general, Michel Jarraud, told the BBC it was likely that La Nina would continue into the summer.

This would mean global temperatures have not risen since 1998, prompting some to question climate change theory.
