September 2012 Tied For The Warmest Ever Recorded | Last month was tied for the warmest September ever recorded globally, according to new data from the National Climatic Data Center. The average combined land and ocean surface temperature last month was 1.21 degrees F above the 20th century average — rivaling September of 2005 as the warmest on record.
In August, the National Climatic Data Center reported that June through August of 2012 was the warmest ever recorded for global land surface temperatures. When factored with ocean surface temperature, the average global temperature between June and August was the third warmest in recorded history. The summer of 2012 was also the third warmest ever recorded for the U.S. — only .2 degrees F lower than the summer of 1936, during the height of the Dust Bowl.
In early September, the climate center reported that January through August of this year was the most extreme for weather ever recorded for the U.S.
