US spring warming off the charts
The United States, excluding Alaska, Hawaii and overseas territories, had an average temperature of 57.1 degrees Fahrenheit (13.9 Celsius) from March through May, 5.2 degrees (2.9 Celsius) above the average from 1901 to 2000, the data showed.
"Spring 2012 marked the largest temperature departure from average of any season on record for the contiguous United States," the National Oceanic and Atmospheric Administration said in a statement.
This year's spring was up 2.0 degrees (1.1 Celsius) from the previous warmest spring in the United States which was recorded in 1910, the agency said.
