Interestingly, even though none of the individual provinces had 2021 (the year of the epic late-June heat wave in western Canada) as the record warmest summer, the average across the 6 provinces did have 2021 as record warmest,...

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.

From Dr. Roy Spencer’s Global Warming Blog by Roy W. Spencer, Ph. D. …but the coolest summer nights have warmed by 5 deg. F. John Christy and I continue to…

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 relentless efforts to police the boundaries...

The Version 6.1 global average lower tropospheric temperature (LT) anomaly for June, 2025 was +0.48 deg. C departure from the 1991-2020 mean, down slightly from the May, 2025 anomaly of +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 deg. C.

A new study from the University of Alabama in Huntsville addresses the question of how much the Urban Heat Island (UHI) effect is responsible for the higher temperatures at weather stations across the world...

But, at best, today’s Politico article entitled, “Meet the 4 influencers shaping Chris Wright’s worldview” is a mix of truths, half-truths, and misleading innuendoes...

"If someone is sure there's greenhouse warming occurring, that's more emotional than scientific because the evidence has been questionable."

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...

The Version 6.1 global average lower tropospheric temperature (LT) anomaly for February, 2025 was +0.50 deg. C departure from the 1991-2020 mean, up a little from the January, 2025 anomaly of +0.45 deg. C.

This is the first of what will likely be a series of posts regarding urban heat island (UHI) effects in daily record high temperatures. My previous UHI work has been using the GHCN monthly average station data of “Tavg”...

The Version 6 global average lower tropospheric temperature (LT) anomaly for July, 2024 was +0.85 deg. C departure from the 1991-2020 mean, up from the June, 2024 anomaly of +0.80 deg. C.

The Version 6 global average lower tropospheric temperature (LT) anomaly for June, 2024 was +0.80 deg. C departure from the 1991-2020 mean, down from the May, 2024 anomaly of +0.90 deg. C.

This sort of “junk journalism” is little more than click-bait for those who believe that climate change is a bigger and more serious issue than growing cities that are overutilizing their own resources and sweltering...
