Wild how all the Warmists tend to making their own liberal cities warmer (note: everything below the headline was a bullet point in the article)
Climate Change Is Driving More Warm Summer Nights in U.S. Cities
Hot summer nights limit our ability to cool off and recover from extremely hot summer days. This can lead to higher heat stress, disrupted sleep, and related health risks.
New analysis shows that the number of unusually warm summer nights has risen since 1970 in 95% of 243 major U.S. cities. On average, these cities now experience 24 more such nights each summer than they did in the early 1970s.
Climate Central also found a growing influence of human-caused climate change on unusually warm summer nights in all of the 247 major U.S. cities analyzed.
Each summer, these cities currently experience an average of 27 unusually warm summer nights with a strong climate change influence, compared to one such night each summer during the 1970s.
The most-affected cities, all located in Puerto Rico and Florida, now experience more than two months’ worth of unusually warm summer nights fueled by climate change each summer.
Asphalt. Concrete. Roads. Large buildings. Less grass and fewer trees. All those vehicles and businesses putting out smog which trap heat at the lower level. All the things that go into the Urban heat island effect.
I’ll bet that we don’t use our AC nearly as much out on the farm as do them city slickers!
Urban areas occupy less than 1% of the Earth’s surface. Does Denier Cult Lieutenant Teach really believe that less than 1% of the Earth’s total land surface occupied by cities and urban environments are fueling global warming?
He IS partly right! Urban areas DO produce some 70% of the increased atmospheric CO2!! Because that’s where BILLIONS people (70% of the population) live and… heat and cool, drive cars and trucks…
He claims that “the number of unusually warm summer nights has risen since 1970 in 95% of 243 major U.S. cities” because of smog. Q: Has smog increased since 1970?
A more likely explanation is that increased CO2 slows the loss of heat overnight, since nights all over the globe are warmer than before. Not just in cities.
And yes, more reflective urban surfaces (roads, parking lots, roofs etc) would lessen visible wavelength absorption and the resultant release of heat.
And all those big new buildings are spewing out heat from their AC units, as well as adding more thermal mass to hold the day’s solar heat and let it back out at night.
And since most weather monitoring comes from places included in or adjacent to urbanization, the temperature measurements are biased toward urban temperatures. (And that’s before all the “corrections” made to the temperature records by biased meteorologists and government departments, who get increased funding for global warming “research”.)
So the Earth is really NOT WARMING?? That’s great news!

As a former concrete producer, I absolutely support more concrete, and fewer asphalt roads and parking lots!
Roofs? I will admit to not understanding how so many people select darker colored roofs. Yes, they might help in the winter but are murder during the summer.
Our denialist from east of the Mississippi typed:
“I will admit to not understanding how so many people select darker colored roofs.”
On that we agree!
White roofs are only good in temperate climates. Not so much in areas that experience freezing temps like Minneapolis or Butte. Commercial buildings like in cities
Something to do with moisture in the ceiling areas and the resulting bad air quality in the buildings.
