Welcome to the new world order. Heat heat and more heat. Here are a few HIGHlights from the latest State of the Climate report from NOAA (May 2012). There is no need for an explanation the data speaks for itself.
The national temperature (US) of 57.1 degrees F during spring was 5.2 degrees F above the long-term average, besting the previous warmest spring of 1910 by 2.0 degrees F. This marked the largest temperature departure from average of any season on record for the contiguous United States.
The spring of 2012 was the culmination of the warmest March,third warmest April, and second warmest May. This marks the first time that all three months during the spring season ranked among the ten warmest, since records began in 1895.
Record and near-record warmth dominated the eastern two-thirds of the nation during spring. Thirty-one states were record warm for the season, and 11 additional states had spring temperatures ranking among their ten warmest.
January-May was the warmest such period on record for the contiguous United States, with an average temperature of 49.2 degrees F, 5.0 degrees F above the long-term average.
The June 2011-May 2012 period was the warmest 12-month period of any 12 months on record for the contiguous United States. The nationally-averaged temperature of 56.0 degrees F was 3.2 degrees F above the long-term average, surpassing the previous record, set last month (May 2011-April 2012), by 0.4 degrees F. The 12-month period encapsulated the second warmest summer, fourth warmest winter, and the warmest spring on record.
