Temperatures across most of the United States in 2013 were relatively moderate. Globally, however, it was an exceptionally warm year.
According to NOAA, 2013 is now tied with 2003 as the fourth warmest year ever recorded on this planet. Earth’s combined average temperature for the year – over both land and sea surfaces – was 58.12°F. That is 1.12°F above the 20th century average. 2013 also marked the 37th consecutive year that our global temperature was above its long-term norm.
While heat dominated most of the planet, Australia was particularly warm. With a mean annual temperature of 71.2°F (2.2°F above average), 2013 was their warmest year on record. Japan and South Korea also experienced their hottest summers ever.
With records going back to 1880, Earth’s top ten warmest years have all occurred since 1998. To date, our warmest year was 2010.
