Notes on data released June 4, 2013: Global average temperatures and the tropics continued a slow cooling drift in May, downward from a warm January, said Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville.
Compared to seasonal norms, during May the coldest area on the globe was in northern Greenland, where the average temperature was as much as 3.75 C (about 6.7 degrees Fahrenheit) cooler than seasonal norms. Compared to seasonal norms, the "warmest" area on the globe in May was in the northern Siberia. Temperatures there were as much as 3.91 C (about 7.0 degrees Fahrenheit) warmer than seasonal norms for May.
