The theme of these articles is whether the historic temperature record is useful for understanding Urban Heat Island Effects.

Urban Heat Island Studies – Do Pristine Weather Stations Even Exist?
Australia’s low population density plus its many weather stations allow many “pristine” station candidates to be examined for studies of Urban Heat Island (UHI) effects.
ClimateTV – URBAN HEAT ISLAND EFFECT – Dramatic New Findings!
The Urban Heat Island effect (UHI) has been known for decades, but it is routinely dismissed by climate advocates as being either insignificant or “we adjust for it” when they…
‘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.
Where Is the Alleged Australian Warming?
Alarming trends are absent from the simple, raw data, presented here Therefore, horrifying trends alleged by others can arise only from manipulating, altering or ignoring the foundational data.
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%).
New Study Suggests Global Warming Could be Mostly an Urban Problem
“For many years, the general public has been assuming that the science on climate change is settled. This new study shows that this is not the case.”
OilPrice.com Contributor Misses the UHI Influence on Phoenix Warming Trend
Data show that the high levels of warming, especially at night and as measured at an airport, are primarily due to urbanization over time, with the modest warming of the…
Houston Recognizes They Have a Problem, the UHI.
Kudos to ABC13 in Houston for reporting honestly on how the UHI affects Houston’s temperatures.
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.
Classifying Land Temperature Stations as Either “Urban” or “Rural” in UHI Studies Proves Nothing about Spurious Temperature Trends
studies have demonstrated that the greatest rate of warming as population increases is for nearly-rural sites, not urban
Urbanization Effects on GHCN Temperature Trends, Part II: Evidence that Homogenization Spuriously Warms Trends
Thus, it appears that NOAA’s homogenization procedure is spuriously warming station temperature trends (on average) when it should be cooling them. I don’t know how to conclude any different.
Urbanization Effects on GHCN Temperature Trends, Part I: The Urbanization Characteristics of the GHCN Stations
I’m convinced that there is spurious warming remaining in the GHCN-based temperature data. The only question is, how much?
Urban Night Lighting Observations Demonstrate The Land Surface Temperature Dataset is ‘not fit for purpose’
Rural data numerically dominate the USA archive, while urban data massively dominate almost everywhere else.
Canadian Summer Urban Heat Island Effects: Some Results in Alberta
Landsat-based estimates of increased urbanization suggest that this has caused a spurious warming component of reported temperature trends, at least for locations experiencing increased urbanization.
The Warming that Happens in Vegas, Stays in Vegas
most of the land data are gathered where people build things… increasingly so.
De-Urbanization of Surface Temperatures with the Landsat-Based “Built-Up” Dataset
But given the fact that all CMIP6 climate models produce U.S. summer temperature trends greater than the NOAA observations means the discrepancy between climate models and observations is even larger than currently…
Claim: Climate Change Is Closing Daily Temperature Gap, Clouds Could Be the Cause
The diurnal temperature range has a significant effect on growing seasons, crop yields, residential energy consumption and human health issues related to heat stress.
Study: The Urban Heat Island Penalty Grows, Especially at Night
From the Pacific Northwest National Laboratory (PNNL), more confirmation of a night-time warming bias in climate records due to increased infrastructure. RICHLAND, Wash.—City living has its perks: Live music, museums,…
Urban Heat Island Effects on U.S. Temperature Trends, 1973-2020: USHCN vs. Hourly Weather Stations
I argue that, based upon the importance of quality temperature trend calculations to national energy policy, a new dataset not dependent upon the USHCN Tmax/Tmin observations is required.
Could Recent U.S. Warming Trends be Largely Spurious?
The official datasets of land surface temperature are (we are told) already adjusted for Urban Heat Island (UHI) effects. But as far as I know, it has never been demonstrated…
More surfacestations project vindication: Strong UHI temperature biases confirmed in USA
WUWT readers may recall that NOAA did an experiment at Oak Ridge National Laboratory that vindicated my findings about the effects of local urbanization on surface temperature measurements. The urban…
Record High Temperatures in France: 3 Facts the Media Don’t Tell You
Reposted from Dr. Roy Spencer’s blog July 2nd, 2019 by Roy W. Spencer, Ph. D. News reporting of the recent heat wave in France and other European countries was accompanied…
Our Urban “Climate Crisis”
By Jim Steele Published in Pacifica Tribune May 14, 2019 What’s Natural Our Urban “Climate Crisis” Based on a globally averaged statistic, some scientists and several politicians claim we are…
