The globally averaged temperature for 2013 tied as the fourth warmest year since record keeping began in 1880, according to NOAA scientists. It also marked the 37th consecutive year with a global temperature above the 20th century average. The last below-average annual temperature was 1976. Including 2013, all 13 years of the 21st century (2001–2013) rank among the 15 warmest in the 134-year period of record. The three warmest years on record are 2010, 2005, and 1998.
Most areas of the world experienced above-average annual temperatures. Over land, parts of central Asia, western Ethiopia, eastern Tanzania, and much of southern and western Australia were record warm, as were sections of the Arctic Ocean, a large swath of the southwestern Pacific Ocean, parts of the central Pacific, and an area of the central Indian Ocean. Only part of the central United States was cooler than average over land. Small regions scattered across the eastern Pacific Ocean and a region of the Southern Ocean south of South America were cooler than average. No region of the globe was record cold during 2013.
