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

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.

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 really don’t...

... it shows humans choose to live under warmer conditions just by living in densely populated areas — and increasingly so.

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.

The bottom line is that an estimated 22% of the U.S. warming trend, 1895 to 2023, is due to localized UHI effects.

This means warming has been exaggerated by at least a factor of 2 (100%).

“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.”

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 past hundred-plus years playing a very small part in...

Kudos to ABC13 in Houston for reporting honestly on how the UHI affects Houston’s temperatures.

For the purpose of taking temperature measurements to build a picture of long-term climate change, there are few places more unsuitable than an airport runway.

The nonlinearity of the relationship is, as other investigators have found, very strong.

studies have demonstrated that the greatest rate of warming as population increases is for nearly-rural sites, not urban

Eventually, all of this will lead to an estimation of how much of the land warming (say, since 1880) has been spurious due to the Urban Heat Island effect.

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.
