Hes’ super thrilled to spend billions upon billions, even though he has no idea what the money would accomplish (via Twitchy)
So, a few thoughts on uncertainty and climate policy. You might not know this from some discussion, but this has been a major research topic

So should I bring an umbrella? If I do, and it doesn't rain, I've borne an unnecessary cost. If I don't, and it does, I get soaked

Huh. I can buy a nice umbrella for $20 or less. And I do it with my money.
So two questions. One is probabilities: how likely is that rain. The other is costs: how heavy is that umbrella, how bad being drenched

Here’s the cool thing: I can look at the weather radar in numerous ways. And, if it looks like rain, I can take the umbrella I paid for with me into the store. No need to spend thousands of dollars (in context of umbrellas) on an umbrella now for when it might maybe possibly “shrugs shoulders” rain during the barbecue festival next October in Rocky Mount.
Climate change is the rain; climate policy the umbrella. What do we know?
1. Climate change could be really, truly, civilization-ending bad

Could be. Hence, let’s spend billions, heck, it really amounts to Warmists wanting trillions, on “I dunno.”
