I have lived in north Alabama or Georgia since 1960 (except for a year in Pensacola, FL 1992-1993), and I remember that every 3-4 years we would have a very cold spell, like 3F. (The coldest I remember was one time it got down to -11F.) But it hasn't gotten down to anywhere as cold a 3F for years.

The year 2011 was the tenth warmest year on record for the globe, but the warmest year on record when a La Niña event was present (Ricky Rood has a discussion of this in his lastest post.) Seven nations and one territory broke all-time hottest temperature records. This is a far cry from 2010 (which tied for the warmest year on record), when twenty nations (plus one UK territory) set all-time hottest temperature records. One all-time coldest temperature record was set in 2011; this was the first time since 2009 one of these records was set. The all-time cold record occurred in Zambia, which ironically also set an all-time hottest temperature record in 2011. Here, then, are the most most notable extreme temperatures globally in 2011, courtesy of weather records researcher Maximiliano Herrera:
Hottest temperature in the world in 2011: 53.3°C (127.9°F) in Mitrabah, Kuwait, August 3
Coldest temperature in the world in 2011: -80.2°C (-112.4°F) at Dome Fuji, Antarctica, September 18
Hottest temperature in the Southern Hemisphere: 49.4°C (120.9°F) at Roebourne, Australia, on December 21
Coldest temperature in the Northern Hemisphere: -67.2°C (-89°F) at Summit, Greenland, March 18. This is also the coldest March temperature ever recorded in the Northern Hemisphere.
Hottest undisputed 24-hour minimum temperature in world history: A minimum temperature of 41.7°C (107°F) measured at Khasab Airport in Oman on June 27
