  • 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 beats the previous all-time record set just two months ago in June 2014 by 0.03°C (0.05°F).
  • The global land surface temperature for the month was 0.99°C (1.78°F) above the 20th century average of 13.8°C (56.9°F), the second highest on record for August, behind 1998.

Warmest Summer on Record

  • The combined average global land and ocean surface temperature for the June–August period was also record high for this period [record keeping began in 1880,] at 0.71°C (1.28°F) above the 20th century average of 16.4°C (61.5°F), shattering the previous record set in 1998.
  • The first eight months of 2014 (January–August) were the third warmest such period on record across the world’s land and ocean surfaces, with an average temperature that was 0.68°C (1.22°F) above the 20th century average of 57.3°F (14.0°C). If 2014 maintains this temperature departure from average for the remainder of the year, it will be the warmest year on record.
  • The average global sea surface temperature tied with 2010 as the second highest for January–August in the 135-year period of record, behind 1998.

June 2014 average land and ocean temperature highest for the month since records began in 1880

The combined global average temperature across land and ocean for June 2014 was the highest for the month, at 0.72°C (1.30°F) above the 20th century average. The previous record was set in June 1998, by 0.03°C (0.05°F), according to the State of Climate Report released by NOAA.

Nine of the ten warmest Junes on record have occurred during the 21st century, including five consecutively since 2010.

“June 2014 also marks the second consecutive month with record high global temperatures. With the exception of February (21st warmest), every month to date in 2014 has ranked among the four warmest for its respective month.”

June 2014 also marked the 38th consecutive June and 352nd consecutive month with a global temperature above the 20th century average.

Selected highlights mirrored from NOAA’s June 2014 State of Climate Report:

  • The combined average temperature over global land and ocean surfaces for June 2014 was the highest on record for the month, at 0.72°C (1.30°F) above the 20th century average of 15.5°C (59.9°F).
  • The global land surface temperature was 0.95°C (1.71°F) above the 20th century average of 13.3°C (55.9°F), the seventh highest for June on record.
  • For the ocean, the June global sea surface temperature was 0.64°C (1.15°F) above the 20th century average of 16.4°C (61.5°F), the highest for June on record and the highest departure from average for any month.
  • The combined global land and ocean average surface temperature for the January–June period (year-to-date) was 0.67°C (1.21°F) above the 20th century average of 13.5°C (56.3°F), tying with 2002 as the third warmest such period on record.

The Ocean

The June global ocean surface temperature was record high, at 0.64°C (1.15°F) above the 20th century average of 16.4°C (61.5°F). “This marks the first time that the monthly global ocean temperature anomaly was higher than 0.60°C (1.08°F) and surpasses the previous all-time record for any month by 0.05°C (0.09°F); the previous record of +0.59°C (1.06°F) was first set in June 1998 and tied in October 2003, July 2009, and just last month in May 2014.”

December Ocean Temperature 2nd Warmest

Posted by feww on January 23, 2010

Overall 2009 Annual Temperatures Joint Fifth-Warmest

The 2009 December global ocean temperature was  the second warmest on record, The US National Oceanic and Atmospheric Administration (NOAA).


The map shows temperature changes for the last decade — January 2000 to December 2009 — relative to the 1951-1980 mean. Warmer areas are in red, cooler areas in blue. The largest temperature increases occurred in the Arctic and a portion of Antarctica. (Image credit: NASA). Click image to enlarge.

The overall 2009 annual temperatures was a joint fifth-warmest, their records show.

“Based on records going back to 1880, the monthly NCDC analysis is part of the suite of climate services NOAA provides. Scientists also reported the combined global land and ocean surface temperature was the eighth warmest on record for December,” according to scientists at NOAA’s National Climatic Data Center in Asheville, N.C.

  • Global temperatures in 2009  tied with 2006 as the fifth-warmest on record.
  • The planet’s land surface temperatures in 2009 tied with 2003 as  seventh-warmest.
  • The overall annual ocean surface temperatures were fourth-warmest, joint position with 2002 and 2004.

Highlights for December 2009

The global ocean temperature was the second warmest on record, trailing 1997.

  • The temp anomaly was about one degree F (0.97ºF) above the 20th century average of 60.4ºF.
  • Global land and ocean surface temperatures combined were the eighth warmest since 1880, at 0.88ºF above the 20th century average of 54.0ºF.
  • The global land surface temperature was 0.63ºF above the 20th century average of 38.7ºF—the coolest December anomaly since 2002.

Global Temperature Highlights for 2009

  • In 2009, the annual global combined land and ocean surface temperature was 1.01ºF above the 20th century average of 58.0ºF sharing joint fifth-warmest position with 2006.

The average decadal temperature for the 2000-09 decade was 57.9ºF, the warmest on record topping the 1990-99 average by 0.02ºF, NCDC scientists said.

Other Heat Highlights

  • December Arctic sea ice cover was  an average of 12.4 million km² (4.8 million square miles),  falling 6.6 percent below the 1979-2000 average extent and the fourth lowest December extent since 1979, when records began.
  • “Antarctic sea ice extent in December was 2.1 percent above the 1979-2000 average, resulting in the 14th largest December extent on record. December Arctic sea ice extent has decreased by 3.3 percent per decade since 1979, while December Antarctic sea ice extent has increased by 0.6 percent per decade over the same period.”
  • Snow cover in Northern Hemisphere during December 2009 was the second largest on record, chasing 1985. “North American snow cover for December 2009 was the largest extent since satellite records began in 1967.”
