That's true, it's a big difference. With nuclear war, every day that the sirens don't ring is the status quo protected, doom delayed by another day. With climate change, every day that the status quo is protected is another day of accelerating doom and increasing inevitability. They are different in that way.

The deniers simply morphed from "it's fake" to "it's unavoidable."

As we all predicted. Because they don't argue in good faith, they're just opposed to ... whatever (science, research, media, school, etc.)
