NOAA Global Analysis of Land and Ocean Temperatures – August 2014

  • NOAA: “The combined average temperature across global land and ocean surfaces for August 2014 was record high for the month, at 0.75°C (1.35°F) above the 20th century average of 15.6°C (60.1°F), topping the previous record set in 1998.
  • The global land surface temperature was 0.99°C (1.78°F) above the 20thcentury average of 13.8°C (56.9°F), the second highest on record for August, behind 1998.
  • For the ocean, the August global sea surface temperature was 0.65°C (1.17°F) above the 20th century average of 16.4°C (61.4°F). This record high departure from average not only beats the previous August record set in 2005 by 0.08°C (0.14°F), but also beats the previous all-time record set just two months ago in June 2014 by 0.03°C (0.05°F).
  • The combined average global land and ocean surface temperature for the June–August period was also record high for this period, at 0.71°C (1.28°F) above the 20th century average of 16.4°C (61.5°F), beating the previous record set in 1998.
  • The June–August worldwide land surface temperature was 0.91°C (1.64°F) above the 20th century average, the fifth highest on record for this period. The global ocean surface temperature for the same period was 0.63°C (1.13°F) above the 20th century average, the highest on record for June–August. This beats the previous record set in 2009 by 0.04°C (0.07°F).
  • The combined average global land and ocean surface temperature for January–August (year-to-date) was 0.68°C (1.22°F) above the 20th century average of 14.0°C (57.3°F), the third highest for this eight-month period on record…
  • With records dating back to 1880, the global temperature across the world’s land and ocean surfaces for August 2014 was 0.75°C (1.35°F) higher than the 20th century average of 15.6°C (60.1°F). This makes August 2014 the warmest August on record for the globe since records began in 1880, beating the previous record set in 1998. Nine of the 10 warmest Augusts on record have occurred during the 21st century. Additionally, August 2014 marked the 38th consecutive August with a temperature above the 20th century average. The last below-average global temperature for August occurred in 1976. The departure from average for the month was also record high for the Northern Hemisphere, at 0.92°C (1.66°F) above average. The Southern Hemisphere temperature was 0.56°C (1.01°F) above average, the fourth highest on record for this part of the world.”
