The National Oceanic and Atmospheric Administration today released its monthly global temperature analysis and announced that June 2010 was the hottest ever in the global temperature record.
The combined global land and ocean surface temperature data also showed that the April-June and January-June periods were the warmest on record. NOAA's National Climactic Data Center maintains climate records that go back as far a 1880.
NOAA, a scientific agency within the US Department of Commerce, "understands and predicts changes in the Earth's environment, from the depths of the oceans to surface of the sun, and conserves and manages our coastal and marine resources."
The agency released temperature data about June, April-June and Year-To-Date time periods, as well as updates on polar ice extent and global precipitation in its State of the Climate full Global Analysis for June 2010. The following is the summary of global temperature highlights NOAA provided today.
Global Temperature Highlights – June
- The combined global land and ocean average surface temperature for June 2010 was the warmest on record at 61.1°F (16.2°C), which is 1.22°F (0.68°C) above the 20th century average of 59.9°F (15.5°C).
- The global June land surface temperature was 1.93°F (1.07°C) above the 20th century average of 55.9 °F (13.3°C) — the warmest on record.
- Warmer-than-average conditions dominated the globe, with the most prominent warmth in Peru, the central and eastern contiguous U.S., and eastern and western Asia. Cooler-than-average regions included Scandinavia, southern China and the northwestern contiguous United States.
- According to Beijing Climate Center, Inner Mongolia, Heilongjiang and Jilin had their warmest June since national records began in 1951. Meanwhile, Guizhou experienced its coolest June on record. According to Spain's meteorological office, the nationwide average temperature was 0.7°F (0.4°C) above normal, Spain's coolest June since 1997.
- The worldwide ocean surface temperature was 0.97°F (0.54°C) above the 20th century average of 61.5°F (16.4°C), which was the fourth warmest June on record. The warmth was most pronounced in the Atlantic Ocean.
- Sea surface temperature continued to decrease across the equatorial Pacific Ocean during June 2010, consistent with the end of El Niño. According to NOAA's Climate Prediction Center, La Niña conditions are likely to develop during the northern hemisphere summer 2010.
April – June 2010 and Year-to-Date
- The combined global land and ocean surface temperature for April-June 2010 was 1.26°F (0.70°C) above the 20th century average—the warmest April-June period on record.
- For the year-to-date, the global combined land and ocean surface temperature of 57.5°F (14.2°C) was the warmest January-June period. This value is 1.22°F (0.68°C) above the 20th century average.
