2012 – Warmest Year on Record

US_Jan-Dec2012_tempanom_300NOAA’s National Climate Data Center (NCDC) announced today that 2012 was the warmest year on record for the contiguous U.S in over a century of record keeping. The average temperature for 2012 was 55.3°F. This is 3.2°F above the 20th century average and is 1.0°F above the previous 1998 record. Other temperature notables for 2012 include: the fourth warmest winter, an extremely warm spring, the second warmest summer, and a warmer than usual fall.

2012 was also the 15th driest year on record for the contiguous U.S., with an average of 26.57 inches, which is 2.57 inches below average. Snowpack totals in the Southern to Central Rockies were less than half of normal; winter snow cover for the contiguous U.S. was the third smallest on record. The minimal snowpack and the persistent dryness of 2011 set the stage for the pervasive drought conditions that occurred in many areas of the U.S. in 2012.

In regards to climate extremes, the U.S. Climate Extremes Index showed 2012 to be second most extreme year on record for the U.S. Catastrophic events such as Superstorm Sandy, Hurricane Isaac, and tornadoes across several parts of the country, gave 2012 the edge over the former extreme weather year of 1998.
