U.S. Record Warmest Year Confirmed by Unprecedented Margin

Midnight Update: The standard deviation of the U.S. annual average temperatures is 0.92, so the new record exceeds the old one by over 1 standard deviation. It's also more than 3.4 standard deviations from the average. According to a public domain table of the normal distribution, the odds of this are 0.0003369. If the distribution were truly random (hint, it ain't), this would be a once in 2968 year event.

Original Post:
The National Climatic Data Center's preliminary report, released within the last hour, confirms that 2012 was the record warmest year for the U.S. by an incredible margin of 1.0°F. All 48 contiguous states were warmer than average for the year, 19 had record warm years, and 26 more had top 10 warmest years. At least 356 individual locations tied or broke their all-time record high temperatures. This included at least one location in every state except Washington.

The NCDC chart of year-to-date temperatures (click to enlarge) to the right shows that the extremely warm January and March put 2012 firmly in first place for warmest year and the wide margin was maintained through December.

The chart of warmest 12-month periods shows that 10 of the top 12 ended in 2012.

From the NCDC report:

In 2012, the contiguous United States (CONUS) average annual temperature of 55.3°F was 3.3°F above the 20th century average, and was the warmest year in the 1895-2012 period of record for the nation. The 2012 annual temperature was 1.0°F warmer than the previous record warm year of 1998. Since 1895, the CONUS has observed a long-term temperature increase of about 0.13°F per decade.

On a statewide and seasonal level, 2012 was a year of both temperature and precipitation extremes for the United States. Each state in the CONUS had annual temperatures which were above average. Nineteen states, stretching from Utah to Massachusetts, had annual temperatures which were record warm. An additional 26 states had one of their 10 warmest years. Only Georgia (11th warmest year), Oregon (12th warmest), and Washington (30th warmest) had annual temperatures that were not among the ten warmest in their respective period of records.
