Well, that’s what all these folks are trying to ignore, I think. And part of it may have to do with having a small window of experience with this issue, which has been going on since at before 1990.
The climate “community” (not sure that’s a great way to describe them, but….” have spent (at least) 27 years now trying to goad the public into action on AGW by scaring the hell out of us with predictions.
The problem is that that strategy is doomed to failure. If you’re wrong, or you’re caught exaggerating, or if the public doesn’t perceive that you were right even when you are, then they take you even less seriously the next time you try to scare them.
We’re now at “peak scare”. You can’t make a prediction about AGW’s future effects that the majority take seriously enough to do anything about. The political capital of AGW has been squandered, and it’s not the fault of the political right that it’s been squandered.
Does that mean we’re all doomed? Nah. There are plenty of measures that government could get involved in that would cost minimal $$$ and have substantial positive effect without much in the way of negatives. But they tend to be bottom-up economic initiatives that the party that is all in on AGW won’t like.
So, stalemate. AGW is a proven fact in my assessment, we’re just waiting for somebody with some common sense to figure out something that will pass political muster.
