Climate Central just ran this piece, which the Washington Post picked up on. They claimed the US was “overwhelmingly hot” in 2016, and temperatures have risen 1.5°F since the 19th century.
The first problem with their analysis is that the US had very little hot weather in 2016. The percentage of hot days was below average, and ranked 80th since 1895. Only 4.4% of days were over 95°F, compared with the long term average of 4.9%. Climate Central is conflating mild temperatures with hot ones.
They also claim US temperatures rose 1.5°F since the 19th century, which is what NOAA shows.
