September 2012 and 2005 are now matched as the hottest Septembers on record. According to the National Oceanic and Atmospheric Administration (NOAA), the average temperature for September 2012 was 60.2 degrees Fahrenheit, 1.2 degrees above normal.  The third highest average temperature for September was in 2003.

It is thought that as summer lengthens due to climate change’s impact on seasonal patterns, September will warm more than other months.

The continued climb of temperatures is melting glaciers around the world, with implications for fresh water availability – a challenge that will impact hydro power generation, agriculture, and drinking water.
