Cliff Mass shows a graph, taken from the Seattle Times, of the hottest temperature each July from 1945 through 2022 at Seattle/Tacoma airport (SEATAC). He then says “… and there is very little upward trend! How could this be?”
Then he goes further:
Just to check on the Seattle Times… I did the same thing for July and August over the past 50 years, plotting the warmest observed temperature at both SeaTac and Pasco (see below).
Hardly any change in the extreme high temperatures each year at either site. No long-term trend….and you would expect a trend if global warming was important for the extreme heat waves!
Unfortunately for Cliff Mass, the data contradict him.
