World warm in September
Global temperatures up, but big chill at South Pole.
For the 12th consecutive year, September temperatures worldwide finished above long-term normals, according to the latest NASA satellite report.
In the 34-year period of satellite record, last month was the third-warmest September on record, said the University of Alabama's John Christy, co-keeper of the data.
The global temperature came in at 0.61 degrees Fahrenheit above normal, with the warmth about evenly distributed between the Northern and Southern Hemispheres.
The big exception was the Anarctic, where the readings were a frigid 6 degrees below normal.
The warming detecting in the last 34 years computes to about 2.5 degrees Fahrenheit per century.
