The whole point is how you change your beliefs in response to new evidence.
Of course the general concept of using a belief as a litmus test for rationality is foolish. But frankly, it’s not possible at this point to have not been introduced to evidence about human-caused global warming. The people to which this test would be applied have been introduced to this new evidence and already failed to update.
And if someone lives in such a secluded bubble of information that they are truly getting information that would lead a rationalist to decry AGW, I think it safe to say that that person is probably not a rationalist. Someone in such a bubble would have no impetus to become a rationalist in the first place.
