My earliest recollection of climate change/global warming was about 30 years ago, and it was understood this was a society and political issue then, and the need for a systematic approach by corporations and government was needed.
Conservatives, Democrats and Republicans, called the most docile claims about global warming/climate change as radical, lies, socialism, communism, anti-business, pro-big government, and so on. The more aggressive claims were impugned as forms of eco-terrorism. It's the same today. The climate change deniers go so far as to insist that all of this is just delusional panic over nothing.
Michael Crichton, science fiction author, was a notable climate change denier who pushed exactly that: this climate change business is nonsense and people who claim otherwise are crazy. He wrote a book on the subject "State of Fear" about how global warming was a fraud, perpetrated by a few to exploit others.
A still sitting U.S. senator, James Inhofe from Oklahoma, says global warming is the greatest hoax ever perpetrated on the American people. And he cited "Dr. Crichton" and his book as the kind of real facts we need to pay attention to, and invited him to testify before Congress as a climate expert and scientist.
It's like humans are designed to make everything a dispute.
