I've been an astronomy and earth sciences buff since I was a kid and my Dad bought me a couple of science books. I've been interested all my life in such things as the birth and evolution of stars, how the earth came to be, plate tectonics, what makes a volcano work, that sort of thing.

But a pretty good catch-up course is "The Making of the Earth," a series on the History Channel (available on DVD, I think).

Astronomers, meteorologists, oceanographers, and earth scientists in general have pretty well plotted the earth's normal cycles—and the normal cycles of the sun that affect the earth. As Amos points out, what has them concerned is the recent anomalies—deviations—from those cycles, particularly the measurable increase in greenhouse gases in the atmosphere that began with the advent of the industrial revolution and has been accelerating since. And with the inevitable effects thereof.

Al Gore is merely reporting these findings.

And—

Well, you know—

Kill the Messenger!!
