SINGAPORE (Reuters) – The pace of global warming continues unabated, scientists said on Thursday, despite images of Europe crippled by a deep freeze and parts of the United States blasted by blizzards.

"It's not warming the same everywhere but it is really quite challenging to find places that haven't warmed in the past 50 years," veteran Australian climate scientist Neville Nicholls told an online climate science media briefing.

"January, according to satellite (data), was the hottest January we've ever seen," said Nicholls of Monash University's School of Geography and Environmental Science in Melbourne.

"Last November was the hottest November we've ever seen, November-January as a whole is the hottest November-January the world has seen," he said of the satellite data record since 1979.

The World Meteorological Organization (WMO) said in December that 2000-2009 was the hottest decade since records began in 1850, and that 2009 would likely be the fifth warmest year on record. WMO data show that eight out of the 10 hottest years on record have all been since 2000.

Scientists say global warming is not uniform in all areas and that climate models predict there will likely be greater extremes of cold and heat, floods and droughts.

"Global warming is a trend superimposed upon natural variability, variability that still exists despite global warming," said Kevin Walsh, associate professor of meteorology at the University of Melbourne.

"It would be much more surprising if the global average temperature just kept on going up, year after year, without some years of slightly cooler temperatures," he said in a written reply to questions for the briefing.
