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.
The problem with the NOAA graph is that it is fake data. NOAA creates the warming trend by altering the data. The NOAA raw data shows no warming over the past century.
The adjustments being made are almost exactly 1.5°F, which is the claimed warming in the article. The adjustments correlate almost perfectly with atmospheric CO2. NOAA is adjusting the data to match global warming theory. This is known as PBEM (Policy Based Evidence Making.) The hockey stick of adjustments since 1970 is due almost entirely to NOAA fabricating missing station data. In 2016, more than 42% of their monthly station data was missing, so they simply made it up. This is easy to identify because they mark fabricated temperatures with an “E” in their database.
