Every month University of Alabama in Huntsville climatologists John Christy and Roy Spencer report the latest global temperature trends from satellite data. Below are the newest data updated through June, 2012.

Southern Hemisphere: +0.20 C (about 0.25 degrees Fahrenheit) above 30-year average for June.
Tropics: +0.14 C (about 0.05 degrees Fahrenheit) above 30-year average for June.
(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)
Notes: Compared to global seasonal norms, June 2012 was the third warmest in the 34-year satellite record, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville. It was the second warmest June in the Northern Hemisphere, second only to June 1998, during the El Nino Pacific Ocean warming event "of the century." It was the seventh warmest June in the Southern Hemisphere and the 11th warmest in the tropics, where rising temperatures may hint at the approach of another El Nino.
