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.
