Topping off the warmest decade in history, 2010 experienced a global average temperature of 14.63 degrees Celsius (58.3 degrees Fahrenheit), tying 2005 as the hottest year in 131 years of recordkeeping.
This news will come as no surprise to residents of the 19 countries that experienced record heat in 2010. Belarus set a record of 38.7 degrees Celsius (101.7 degrees Fahrenheit) on August 6 and then broke it by 0.2 degrees Celsius just one day later. A 47.2-degree Celsius (117.0-degree Fahrenheit) spike in Burma set a record for Southeast Asia as a whole. And on May 26, 2010, the ancient city of Mohenjo-daro in Pakistan hit 53.5 degrees Celsius (128.3 degrees Fahrenheit) -- a record not only for the country but for all of Asia. In fact, it was the fourth hottest temperature ever recorded anywhere.
