July 2018 USA – 1936, 1934 and 1901 (tied with 2012) Are Still the Hottest (Maximum) in USA.
2018 is 19th. I’m using Maximum Temperature. Not Average.

Alberta Average July Tmax By Decade
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).

July USA – 1936, 1934 and 1901 (tied with 2012) Are Still the Hottest (Maximum) in USA.
Correction: 2017 is 15th. 2017 is tied for 14th.
Clarification: I’m using Maximum Temperature. Not Average.
Woodstock Ontario – Coldest July Tmax in 142 Years
Using Environment Canada monthly summaries, Woodstock Ontario had the coldest average Tmax for July since 1872 (which is when the data starts).
Warm July’s seem kind of cyclic too on this graph.
This graph is just July’s monthly anomaly from the 1981-2010 average.
Indiana Didn’t Get the Memo About CO2 Causing Warming
USHCN Infilling – A rebuttal to Nick Stokes
Nick Stoke and Zeke Hausfather don’t like my graphs showing a difference between Estimated (infilled) and non-Estimated (not infilled) USHCN data
Nick said:
“The difference between average estimated and average non-estimated, doesn’t reflect estimation. It just reflects changes in the kind of stations that were being estimated.
For some reason, they were more likely to be warmer. I don’t know why, but they were. It’s just the wrong way to do it.”
I’m not sure I believe in coincidences.
I believe Nick and Zeke both created an anomaly baseline for each month for each station. Nick used 1900 to 2013. Zeke said he used 1961-1990.
Neither of them added trend lines.
I believe both used all the data (infilled and non-infilled). (As of my posting this they had not confirmed). I disagree with that. Infilled data should not be used in the baseline.
As an example of what infilling does using the difference by station from the 1895-2013 baseline here is Dec 1998 to 2013 Tmax.
In this case, the real data had a downwards trend of -0.82C/decade and the infilled data was -0.64C/decade which is .18C/decade higher not because infilled data was hotter, but because it was less cold.
From 1895 to 2013 the infilled trend is consistently .02C/decade to .03C/decade higher than the non-infilled trend.
The red dots are higher on the 1980 and later side of the graph while they are lower on the pre-1960 part of the graph.
Cooling the past, warming the present.
Misleading Information About USHCN At Judith Curry’s Blog
Zeke has an post over at Judith Curry’s blog where he makes a claim that “infill has no effect on CONUS-wide trends” (among other claims).
I disagree. Here are the 12 months comparing Estimated and Non-Estimated and then all the data. Blue = Final data (non-Estimated) Red = Final Data Estimated Green = All Final Data.
Infilling does change the trend. For example, Estimating changed the trend in Dec from .06C per decade to .07C per decade because the Estimated data had a trend of .15C/decade.
