New paper finds US extreme heat waves have decreased since the 1930’s – Published in Journal of Applied Meteorology and Climatology
Study 'finds that US extreme heat waves have decreased over the period from 1930-2010. According to the authors, "Several daily maximum [Extreme Heat Events] near the 1930’s led to 1930-2010 trends of daily maximum [Extreme Heat Events] decreasing" and "Maps indicated negative trends in the interior of the [continental United States] and positive trends in coastal and southern areas. Continental scale increases between 1970 and 2010 were mostly offset by the decreases between 1930 and 1970." In other words, the overall trend of US extreme heat waves was a decrease from the 1930's to the ice age scare of the 1970's, and then a return to levels still shy of those in the 1930's.
