Temperature records tumbled in Russia, Saudi Arabia, Sudan, Burma and Pakistan, causing heatwaves and devastated harvests
2010 was the year of the heatwave, with record temperatures set in 17 countries. Two leading groups of scientists say it was the warmest since records began in 1850; another suggests it was the second-warmest.
But the year that saw an unprecedented month-long heatwave in Russia will be followed by cooler global temperatures in 2011, say climate scientists monitoring sea temperatures in the Pacific that are thought to determine temperatures around the world.
