The U.N. body, the World Meteorology Organisation said that 2010 was one of the three warmest years on record. A report from Geneva says, December may have seen bitterly cold weather across much of Europe but that doesn't change the fact that the Earth is getting warmer. It said, Arctic Sea Ice cover was at the lowest level ever last December. The Organisation believes these latest statistics should finally lay to rest any doubt about the existence of global warming.
