Michael Crichton wrote a book named State of Fear in which he attacked the myth of global warming, pointing out that measurements of temperature change were not consistent globally, suggesting that instead local effects were responsible for warming.
The liberal establishment basically crucified him and he died of cancer a few years later.
However, as has happened with every one of his theories in his books dating back to the 1960s, Crichton was right. Check out this entertaining report from China:
Researchers have found evidence that the pollution engulfing Chinaâ€™s cities enhances the warming effect of cityscapes, raising the temperature by one degree Celsius. Writing in Nature Communications, they say itâ€™s not the bigger cities that suffer the most, but those with the worst of a certain type of air pollution.
Cities tend to be hotter than countryside areas because of the Urban Heat Island effectâ€”the density of buildings and the materials they are built out of absorb heat and radiation from the sun extremely well, but donâ€™t readily release it at night, keeping the area warmer for longer.
As written here some years ago, the culprit in cities is most likely the vast amount of concrete used because it holds on to both heat and moisture unpredictably, and covers over natural regulatory mechanisms like earth and forest. Those tend to absorb water during the day and release it just before dawn, creating a natural cooling cycle.
In addition, heavy particulate pollution like that from car exhausts creates a kind of blanket over the city which increases its temperature. For a great example, examine Los Angeles: a flat plain in a large desert valley, it gets hottest when the smog serves as an insulator. After a rain, when smog is visibly reduced, the city is cooler and the air better.
Global warming is a proxy for human effects on the environment. As usual, humans have created a phantom problem that is smaller than the real problem, which is huge. The huge real problem is overpopulation, because on a finite earth, the more people we cram into it the more we exclude nature, including these regulatory mechanisms. People are terrified of that idea, so instead they are campaigning against actually functional appliances and non-electric cars, pretending that this pretentious course of action avoids a problem because it addresses one part of it.
As more evidence comes out which shows that global warming is a local problem, the herd will have a panic attack because then, the big problem will come into view. That problem requires us telling some people they cannot breed or migrate, which violates the Leftist feel-good ideal of equality, and will precipitate the downfall of Leftism as a concept.
