Tuesday’s global average temperature was calculated by a model . . . to estimate daily average temperatures starting in 1979.
“This is our ‘best guess’ of what the surface temperature at each point on earth was yesterday,” [Paolo Ceppi] said.
WaPo, of course.
Meanwhile, back in the real world of actual measurement, the highest maximum at KGRR so far in 2023 was 91 degrees F, on three days in June.
And the hottest 4th of July was way back in 1911. Yesterday made it to 89.
Maximum temperature observed has been in decline here for decades.
