"How do you talk to someone who doesn't believe in climate change?"
That was actually the first sentence to an introduction to a TED talk (screencap above), and it illustrates a big part of the problem with Anthropogenic Global Climate Change (AGCC) fanatics. Their condescending need to preach at the rest of us is annoying, as is their conviction that we could be won over to their side.
First of all, climate changes. Very few people seriously doubt that. The Earth has been both a snowball and a sauna in the past. I completely "believe in" the evidence that this has happened and will continue to happen. That's not what they are talking about when they say "doesn't believe in climate change".
They are talking about the fact that intelligent, informed people don't necessarily worship with their cult of AGCC belief and their preferred social agenda, and they can't bear it. That's it.
The best way to "talk" to someone who "doesn't believe in climate change" is ... don't. Stay quiet. But if you can't mind your own business, and you ignorantly (and unwisely) broach the subject, maybe you could at least listen to the reasons why they aren't in your cult. If you can't do even that much, then drop the religious devotion to your cult before opening your mouth. No one wants to hear it.
Second, it would help if you would recognize that what you are promoting isn't science. AGCC believerism is partly science; mostly collectivist politics. When you mix politics with science (by funding it through theft, for example) what results is less science than politics. This brand of politicized "climate science" cherry picks data, relies on completely unreliable models (computerized guesswork which is never, NEVER reliable), ignores economics, and violates ethics-- all of which would need to be taken into account for AGCC believerism to be credible enough to be taken seriously. They ignore all the inconvenient factors, which is why they aren't credible, no matter how much they posture and preach. No matter how much they try to talk down to those who aren't falling for their violently imposed "solutions".
I believe the Earth's climate changes over time. I accept that it is possible human activities have changed the rate of change by adding atmospheric carbon dioxide. I don't doubt there is some amount of atmospheric carbon dioxide which would be trouble. I acknowledge that it is possible, although unlikely, that this climate change is entirely negative, with no benefits at all. I am more open-minded and scientifically oriented on this topic than any AGCC believer. And yet I'm not one of them and can't support them in any way. That offends their feelings.
I doubt their "solutions" are solutions. I know they aren't ethical-- more government control never is. If they get their way more problems will be created, yet they won't be held accountable. You can't let the perpetrator of the greatest amount of environmental damage-- The State-- tell everyone else what they are allowed to do. Not on this planet or any other. Denying this reality is science denial.
I am completely in favor of businesses and individuals finding ways to reduce pollution of every sort. It's dumb to foul your own nest. I am not in favor of imposing "solutions" at the barrel of a government gun, no matter what someone imagines will happen otherwise.
