Was last month warm where you live? If so, you weren't alone. According measurements taken by the National Oceanic and Atmospheric Administration (NOAA) June 2010 was the hottest June on record worldwide. But this is not a new trend, at least for this year. March, April, and May 2010 were also the warmest on record. This was also the 304th consecutive month with a global temperature above the 20th century average. The last month with below-average temperature was February 1985.
Here are some of the numbers:
* The combined global land and ocean average surface temperature for June 2010 was the warmest on record at 16.2°C (61.1°F), which is 0.68°C (1.22°F) above the 20th century average of 15.5°C (59.9°F). The previous record for June was set in 2005.
* The June worldwide averaged land surface temperature was 1.07°C (1.93°F) above the 20th century average of 13.3°C (55.9°F)—the warmest on record.
* It was the warmest April–June (three-month period) on record for the global land and ocean temperature and the land-only temperature. The three-month period was the second warmest for the world's oceans, behind 1998.
* It was the warmest June and April–June on record for the Northern Hemisphere as a whole and all land areas of the Northern Hemisphere.
* It was the warmest January–June on record for the global land and ocean temperature. The worldwide land on average had its second warmest January–June, behind 2007. The worldwide averaged ocean temperature was the second warmest January–June, behind 1998.
* Sea surface temperature (SST) anomalies in the central and eastern equatorial Pacific Ocean continued to decrease during June 2010. According to NOAA's Climate Prediction Center, La Niña conditions are likely to develop during the Northern Hemisphere summer 2010.
