Climate Central says the urban heat island effect may be increasing urban (and even rural) areas near Houston.
The idea is that urban areas have features that lead to higher temperatures – like asphalt roadways that heat up hot in the sun.
An urban heat mapping project in Portand, Oregon found temperatures varying by 10 to 15 degrees, sometimes within as little as a block apart.
I read elsewhere that night time temperatures in Phoenix may be increasing – but possibly because in today’s world, nearly every residence has an air conditioner that runs all night. The AC is basically a heat pump that cools the house by pumping indoor heat out to the AC unit’s radiator, which radiates the heat to the outdoors. If every house is heating the Pheonix night air, what does that do to night temperatures?
I have no answers for any of this. Just asking reasonable questions.
