David Leonhardt, in his Op Ed piece Overcome by Heat and Inertia the same day in the New York Times, pointed out
"This city (Washington) just endured its hottest June since records began in 1872, according to the National Oceanic and Atmospheric Administration. So did Miami. Atlanta suffered its second-hottest June, and Dallas had its third hottest.As the old saying goes, "There are none so blind as those who WILL NOT see".
"In New York, the weather was relatively pleasant: only the fourth-hottest June since 1872. Then again, New York is on pace for its hottest July on record."
