Ever hear of the H.A.B. theory?
In short, since the poles are always sub-freezing and therefore precipitation never melts, it accumulates.
Since the Earth rotates on an axis that is not perpendicular to the Sun, every 15,000 or so years the Earth "wobbles" onto it's side (like top).
So almost instantiously, the poles are moved to the equator and the equator becomes the poles.
“Hmmmm - and since reptiles can only live where it is warm (they are cold blooded) - it means there was global warming (and cooling) millions of years ago!!!!”
Well, considering that oxygen we breathe is largely a waste product of plants and some small organisms, yes, our atmosphere has changed dramatically over the great arc of time. Yet somehow life has endured. The problem with the worst of the global-warming fear-mongering is that it pretends humans, and other animals, are incapable of surviving if the environment changes. Life as we know it wouldn’t even EXIST if we didn’t have that ability. Is it possible that our planet is changing for the worse? Perhaps... I’m not obnoxious enough to pretend I know the answer. But the idea, perpetrated by the likes of Al Gore, that it means the end of the world is dishonest at best.
