I just listened to a radio interview where Andy Dessler of Texas A&M stated that 2012 was the warmest on record for the contiguous United States, beating the previous record by a full degree in temperature. He also claimed that the average temperature in 2012 in the contiguous United States was 55.3 degrees Fahrenheit (12.94 degrees Celsius), 3.2 degrees above the average recorded during the 20th century and 1.0 degree above 1998, which until now was the hottest on record.
These claims are simply false.
It is rather mystifying that NOAA continues to deceive people in their press releases. NASA and NOAA have continuously altered the temperature record to cool the past and warm the present. For example, look here.
