You aren't being instructed to believe something based on faith. You're encountering evidence you disagree with and making up, which is to say hallucinating, the idea that the evidence of science is something that is like faith.
It is nothing like faith.
Don't make your problem with the available evidence a question of faith or you discredit faith.
Like I said, don't bring faith into politics.
If you believe that people who believe climate change is an emergency are taking part in a faith-based movement that is a huge logical error on your part.
Faith is a personal choice. Examining evidence and coming to a conclusion about what is real is a matter of logic and reasoning. They are completely different, and mixing them is not just poor form, it exposes your motivated reasoning.
