Also, it's not true that I cherrypicked the summer months. At Flint, the change in annual temperatures is just as great if not more. It is true that Detroit's annual mean has not "shifted" quite as much as the summer mean, but very close. Looking at the past 13 years, the annual mean at Detroit is within a couple tenths of a degree of the 1961-1990 average for Columbus and Dayton, Ohio.

The values below compare 2010-2022 (13 years) at Flint to 1961-1990 averages at Toledo and Findlay, Ohio. I expect the Flint average to come up another tenth of a degree when 2023 is finished, but I've excluded 2023 since it's still in progress.

First up is annual mean for Flint. The past 13 years have averaged 49.2F for the annual mean.

At Toledo, the 1961-1990 average for annual mean was 48.5F.

At Findlay, the 1961-1990 average for annual mean was 49.5F.

The annual mean temperature at Flint over the past 13 years has been 0.7F warmer than the 1961-1990 normal at Toledo, Ohio and 0.3F cooler than the 1961-1990 normal at Findlay, Ohio.

And I can already anticipate the next objection. Oh - but it's mostly being driven by warmer low temperatures. Wrong! The annual mean maximum temperature has shifted even more than the annual mean average temperature.

The mean average annual maximum temperature at Flint, Michigan over the past 13 years has been an astounding 59.1F.

This is 0.5F warmer than the mean at Toledo for 1961-1990.

And 0.7F warmer than the mean at Findlay for 1961-1990.
