This time series also shows the 2012 year-to-date temperature through November. Outcome scenarios based on persistence of temperature for December, the remaining month of 2012, are shown. The January-November 2012 contiguous U.S. average temperature was 57.1°F, 3.3°F above average. The nationally-averaged temperature for December 2012 would need to be more than 1.0°F colder than the coldest December (1983) for 2012 not to be the new record warmest year. The data for 2012 are preliminary.
