I posted some data about temperatures in Edmonton and Alberta. I wanted to visualize it. So I’ve made a grid.
The source of the data is Environment Canadas monthly summaries.
I’m using Tmax, not Tmean. (The logic being that max temps are the problem)
And I’m starting with the July only average for the decade. (I’ll expand in later posts).
There are 1087 stations with July data in Alberta.
I’m narrowing it down to stations with 25 years of data and data all the way up to 2017 and 80% complate.
Things to note:
Only 29 stations make the cut. Only 1 station has the 2010s as the decade with the hottest July average Tmax.
Only 2 stations have data from the 1940s (none before that).
So … AGW ain’t going to kill Albertans in July. They already survived July in the 2000s.
And there isn’t any stations with old and new data. (By that I mean the 30s).

Do you have the data for nighttime lows? I was thinking I saw that most of the temperature increase was due to higher nighttime lows rather than daytime highs. I have never seen an explanation for that phenomena.
I’ll do the lows soon.
