COPENHAGEN (AP) - The world's weatherman says this decade has very likely been the warmest in the historical record, and 2009 likely will end as one of the warmest years.
The World Meteorological Organization released the data in Copenhagen on the second day of a pivotal 192-nation climate conference, where delegates are working to craft a global deal to step up efforts to stem climate change.
Michel Jarraud, WMO secretary-general, says the decade 2000-2009 is "very likely" the warmest since record-keeping began in 1850, and 2009 is likely to be about the fifth-warmest year on record.
Meanwhile, British Prime Minister Gordon Brown has suggested one way to turn up the heat on the U.S. and others is for Europeans to raise their own bid on reducing greenhouse gas emissions.
Brown told The Guardian newspaper on Tuesday he hoped the EU would pledge to cut emissions by 30 percent by 2020, compared to 1990. The EU's current target is 20 percent cuts.
