Your first sentence will be the same sentence used to justify the AI models that will be used by the government to impose other tyrannical laws in other areas of your life besides climate change. And they will wash their hands of responsibility by saying "we trusted the best models at the time made by the best experts!"

But the whole thing is just misdirection for their tyrannical desires. It's already working on you and you are wondering how it will ever work. Which is why I mentioned cognitive dissonance.
