If anyone wonders why some resist accepting climate change as a fact, the above statement gets to a big piece of the underlying puzzle. I strongly suspect that if climate change was merely a scientific topic, there would be little-to-no resistance to accepting it as fact.
But it's not just a scientific question, it's (been made into) a question of how humans fundamentally live on the planet. And so of course a subset of society is going to resist societal change. It's not that people are particularly stupid, it's that they don't like the fundamental changes to how they live that they believe will follow.
Of course, we all know all of this, but for some reason we like to pretend we don't.
In my personal opinion, if you truly care about stopping climate change, you should be spending our effort developing solutions that do NOT require fundamental changes in how humans live on this planet. That path is much more likely to be successful in the political realm and thus more likely to actually save the planet.
