I propose that people take indefensible positions like climate denial and Trump support simply out of fear
This story picks up where an earlier post left off a few weeks ago. Then, I discussed some of the political realities associated with inaction on climate change. In that post, I said I would revisit the question of why so many people deny the evidence of a changing climate. Now is the time for that discussion.
What continually befuddles people who work on climate change is the vehement and indefensible denial of evidence by a small segment of the population. I give many public talks on climate change, including radio and television interviews and public lectures. Nearly every event has a few people who, no matter what the evidence, stay in a state of denial. By listening to denialist arguments, I find they fall into a few broad categories. Some of them are just plain false. Examples in this category are ones like:
There was a halt to global warming starting 1998.
Humans are only responsible for a tiny fraction of the greenhouse gases in the atmosphere.
Scientists are colluding to create this fraud.
Others are not false but are completely irrelevant. For example:
Climate is always changing.
We didn’t have thermometers a million years ago to measure global temperatures.
Cities are hotter than their surroundings.
Why would people think things or repeat statements that are known to be false or irrelevant? I am convinced that for the vast majority of people, they are not intentionally being incorrect. Something must be forcing them to be wrong. What could that be? Why are people so willing to believe and repeat lies?
That brings me to the connection with President Trump. His sheer number of falsehoods and flip-flops is so great, you lose track of them all. For instance, let us take the so-called wall to stop illegal immigration. First he said Mexico will pay for it and it will be “so tall;” now, he wants it to be paid by the US taxpayer. He falsely exaggerated the number of jobs that have been created since he came into office. He made false statements about the size of his electoral win. He made false statements about President Obama’s birthplace. He has made false and unsupported claims about voter fraud. He has made false claims about climate scientists.
Finally, there is the current investigation into his and his…
