It doesn’t. But anybody with a PhD in so much as basket weaving can be a “climatologist” and an “expert” on global warming for the MSM ........
BS = Well, you know what that means
MS = More of the Same
PhD = Piled Higher and Deeper
Actually that was 1 of the huge problems with all those claims about how much “scientific” support there is.
1 of the problems being exactly the Clintonian smoke&mirrors language: “millions of SCIENTISTS agree”. Well, sure, they’re “scientists”, but they weren’t involved in climatology specifically!
The other problem being they fraudulently included scientists who did NOT sign on.
