If it is on PBS, I generally wouldn't watch it. I used to like NOVA, but like National Geographic and rags like Scientific American, they have gone fully left.

The salient point to keep in mind is:

It is not in question that climate change happens or that temperatures may be rising or falling over time, that will cause the planet to change. It does. The question is whether those changes are caused by man, and whether they will be catastrophic.

They aren't caused by man, and they may or may not be catastrophic no matter what we do or say.

The next question is how would you even begin to evaluate the impact of changes made by man.

First you would need to start with a climate model that works.

They don’t have one.

Game, set, match.
