Canada Summer Daily High Temperature Trends, 1900-2023
Over the period 1900-2023, the average summer (JJA) daily high temperatures across the six southernmost large provinces of Canada (British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, and Quebec) show no trend.
“High Priests of Consensus Panic: The NYT’s Meltdown Over Scientific Skepticism”
The real story here is not the hiring of three scientists who are willing to question received wisdom. The real story is the media’s all-consuming need to delegitimize dissent, their…
UAH v6.1 Global Temperature Update for May, 2025: +0.50 deg. C
The Version 6.1 global average lower tropospheric temperature (LT) anomaly for May, 2025 was +0.50 deg. C departure from the 1991-2020 mean, down from the April, 2025 anomaly of +0.61…
35 years ago today, NASA space scientist Dr. Roy Spencer had climate exactly correct
“If someone is sure there’s greenhouse warming occurring, that’s more emotional than scientific because the evidence has been questionable.”
Examining the Global Carbon Project’s Estimates of CO2 Sources and Sinks, 1959-2023
So, what I did was to examine how well each individual model estimate (or sometimes an observational estimate) helped to explain the yearly CO2 increases at Mauna Loa. I then…

The Version 6 global average lower tropospheric temperature (LT) anomaly for May, 2024 was +0.90 deg. C departure from the 1991-2020 mean, down from the record-high April, 2024 anomaly of…
Dr. Roy Spencer: New Article on Climate Models vs. Observations
…here’s a comparison between models and observations for the U.S. Corn Belt near-surface air temperatures in summer:
UAH Global Temperature Update for December, 2023: +0.83 deg. C
The Version 6 global average lower tropospheric temperature (LT) anomaly for December, 2023 was +0.83 deg. C departure from the 1991-2020 mean, down from the November, 2023 anomaly of +0.91…
UAH Global Temperature Update for November, 2023: +0.91 deg. C
The Version 6 global average lower tropospheric temperature (LT) anomaly for November, 2023 was +0.91 deg. C departure from the 1991-2020 mean, statistically unchanged from the October, 2023 anomaly of…
‘Demographic Warming’: Humans Increasingly Choose to Live Where It’s Warmer
… it shows humans choose to live under warmer conditions just by living in densely populated areas — and increasingly so.
UAH Global Temperature Update for September, 2023: +0.90 deg. C
With the approaching El Nino superimposed upon a long-term warming trend, many high temperature records were established in September, 2023.
Summer warming 1895-2023 in U.S. cities exaggerated by 100% from the urban heat island effect
This means warming has been exaggerated by at least a factor of 2 (100%).
UAH Global Temperature Update for July, 2023: +0.64 deg. C
July 2023 was an unusual month, with sudden warmth and a few record or near-record high temperatures.
Americans Increasingly Choose a Warmer Life
There’s a reason why people are flocking to Texas and Florida, and not to the Dakotas or Maine.
Urbanization Effects on GHCN Temperature Trends, Part IV: UHI Effects on Tmax and Tmin
The nonlinearity of the relationship is, as other investigators have found, very strong.
