The first rule in politics is the same as the first rule in sales. Create a sense of urgency. Act now as supplies are limited! This deal valid only for the next hour. Coupon valid only through the fifth. Or, in politics, if we don’t act now, we’ll all drown in less than ten years! The situation will be irreversible! (I’ve been hearing this hysteria since grade school in the sixties. Total death and disaster, or peak oil, or over population, was always just ten years away. I can’t tell you how tired I am of it, but I guess it still serves to create hysteria in the young or ill-informed.)
Saying the situation is already too late is pretty much admitting that the sale has failed. It’s also stupid for sales. It’s saying, in effect, hey, you could have saved the world, but it’s too late.
I guess we should all go to our mountain redoubt and close the door after us. Incidentally, the premise behind many movies and TV shows is that global warming happened, and the story is as a result of that. As soon as the narrator says something to that effect, I click it off.
The Nazis wrote the book on it.
