Liberals usually find themselves frustrated when they encounter climate change doubters who just won’t accept that the planet is warming (or cooling) and refuse to accept that the science is settled. (The Associated Press has even advised its reporters to use the term, “those who reject mainstream climate science.”)

MSNBC host Christopher Hayes admits that he just doesn’t know what to do with Sen. Marco Rubio’s outrageous claim that the climate has always been changing.

So you could call Rubio a believer in climate change. That’s a good thing, right? Not the way Rubio stated it, it’s not.

That would depend on Miami being completely submerged sometime during Rubio’s lifetime, for one thing.

So did Hayes, apparently. That’s why Obama needs a third term: to finish lowering the oceans to their correct depth.
