Considering we're now at the very beginning of a new solar cycle, don't be surprised if our climate begins another wacky period.

BTW, you ARE aware, aren't you, that there were palm trees in the arctic regions roughly 1 million years ago. Thought so.

Back to topic...

I wonder how many people realize that approximately every 10,000 years, the earth's axis changes to its opposite. Obviously, this means that it's not constant, and that it shifts ever so slightly during these 10,000 years, very slowly creeping toward its opposite end. What this means is that whereas now the Northern Hemisphere experiences spring and summer every March and June, respectively, this is only temporary. Sometime in the not too distant future, our summer here will begin around December 21st and winters around June 21st. It ought to be interesting to see what sports schedules are like then.

Axis doesn't shift. Magnetic poles reverse themselves periodically Magnetic north become magnetic south and vice versa. Continental drift is what occurs. Contintents are moving. All you have to do is look at a map of the earth and this is quite evident. At one tim e all of the Continents were joined as one super continent. Geologists called this continent Pangea.
