I've never been there, so I can't say that they aren't.
But the ultimate conspiracy theory about the weather is that "global warming" and "climate change" are just the coverup.
The earth is shifting and increasing its tilt, so summers are hotter and winters are colder. (They do admit that the spin rate of the core has changed, but not the gyroscopic effect that that has caused).
Of course, all that is predicated on the theory that the earth is roundish rather than flat. So the Flat Earthers are probably part of the conspiracy, as well.
In any event, everyone living on the earth is going to eventually die.
Hey, no spoilers here!
