     This file, includes embedded formulas.  ’12 = 1 / X Yrs means how many years till the heat experienced in the summer of 2012 is likely to recur, if climate is not changing.  2012 warming near the coasts was nothing out of the ordinary (and cooler than usual in some places - including states Alaska and Hawaii and cities Oakland, Astoria, Boston - and almost cooler than normal in the South Atlantic and West Coast states generally).

   Yrs to 50/50 means how long till 2012 heat becomes the New Normal, if climate is changing.  Statistically, the number of years till then depends partly on the city (or region)-specific standard deviation of the average of 41 (or 21) “summer" daily high temperatures from the corresponding average of the 122-day (June 1 - Sept. 30) “summer" averages.

    And at the right is the update after 2 more years.  Below that is the update summary for the regions and below that is the original summary by region and details by city just thru 2017.  In the past 2 years, warming increased in the West Coast, Northeast, East North Central and (barely) in the West North Central.  It decreased in the West South Central, Rockies, East South Central and (barely) South Atlantic.
