First quarter of 2012 also warmest on record; early March tornado outbreak is year's first "billion dollar disaster"
According to National Oceanic and Atmospheric Administration (NOAA) scientists, record- and near-record breaking temperatures dominated the eastern two-thirds of the nation and contributed to the warmest March on record for the contiguous United States, a record that dates back to 1895. Over 15,000 records were broken as March 2012 became the warmest on record.
The average temperature of 51.1 degrees F was 8.6 degrees above the 20th century average for March and 0.5 degrees F warmer than the previous warmest March in 1910. Of the more than 1,400 months (or more than 116 years) that have passed since the U.S. climate record began, only one month, January 2006, has seen a larger departure from its average temperature than March 2012.
