July 9, 2008-- A La Nina Pacific Ocean cooling event continues to drive tropical and global temperatures: Globally, June 2008 was the coolest June since 1999, according to Dr. John Christy, director of the Earth System Science Center at The University of Alabama in Huntsville.
While the La Nina is a tropical event, cool temperatures covered a large portion of the globe. Among the past 30 Junes, June 2008 was the third coldest south of the Antarctic Circle, fourth coolest in the Southern Hemisphere and fifth coolest in the tropics.
The Antarctic continent saw its third coldest June in 30 years, with temperatures averaging -1.53 C cooler than the seasonal norm. Portions of Anarctica south of Australia were as much as 5.5 C (9.9 degrees Fahrenehit) colder than seasonal norms for the first month of winter.
While La Nina has caused global average temperatures to fall by more than 0.7 C (about 1.26 degrees F) since January 2007, June was only the eleventh cooler than normal month since January 1999.
