July 2012 Global Temperatures 4th Warmest on Record


FROM:  NOAA/NCDC:
             According to NOAA scientists, the globally-averaged temperature for July 2012 marked the fourth warmest July since record keeping began in 1880. It also marked the 36th consecutive July and 329th consecutive month with a global temperature above the 20th century average.
            Most areas of the world experienced higher-than-average monthly temperatures, including most of the United States and Canada. Meanwhile, Australia, northern and western Europe, eastern Russia, Alaska, and southern South America were notably cooler than average. In the Arctic, sea ice extent averaged 3.1 million square miles, resulting in the second lowest July sea ice extent on record.

Global Highlights

  • The average combined global land and ocean surface temperature for July 2012 was 0.62°C (1.12°F) above the 20th century average of 15.8°C (60.4°F). This is the fourth warmest July since records began in 1880.
  • The globally-averaged land surface temperature for July 2012 was the third warmest July on record, at 0.92°C (1.66°F) above average.
  • The Northern Hemisphere land surface temperature for July 2012 was the all-time warmest July on record, at 1.19°C (2.14°F) above average.
  • ENSO-neutral conditions continued in the eastern equatorial Pacific Ocean during July 2012 as sea surface temperature anomalies in that region continued to rise. The average July worldwide ocean surface temperature ranked as the seventh warmest July on record.
  • The combined global land and ocean average surface temperature for January–July 2012 was the 10th warmest such period on record, at 0.53°C (0.95°F) above the 20th century average.
