The new normal is warmer.
That's the assessment of the nation's top weather agency, which releases data Friday that show the 30-year "normal" temperature in the United States.
"The climate of the 2000s is about 1.5 degree Fahrenheit warmer than the 1970s, so we would expect the updated 30-year normals to be warmer," said Thomas R. Karl, director of NOAA's National Climatic Data Center. That recent temperature trend was enough to drag the three-decade moving average, from 1981-2010, up by half a degree Fahrenheit from the 1971-2000 period, according to the report by the National Oceanic and Atmospheric Administration.
