It's true. Believe it.

On second thought, don't believe it, KNOW it, because it is a FACT, which is not something you take on faith.

We are in a period of accelerated global warming and it has a man-made component, if not cause. It is making the world unlivable for our form of life, and if we start now we can still do something about it. But time is short.

This fact was brought to my clear understanding this weekend by "An Inconvenient Truth," the new documentary featuring Al Gore. He is GREAT in the movie by the way. Funny, unhurried, secure in the truth of his statements. Very impressive.

The movie brought up tons of interesting information. For instance, we can tell the temperature of the world going back hundreds of thousands of years, mainly by drilling into the Antarctic ice. From these core samples progressive shavings are taken, and from the oxygen isotopes in the air trapped in the bubbles in each shaving they can determine the temperature. The time is known because they know the amount of accumulation each year.

The point is, when you look at a graph of this, you can see the range around an average, and you can see the last few ice-ages, and the last few warming periods, and then there is us now. We are so far out of range and it is happening so rapidly, it simply can't be a natural process. The only variable is us, it must be us.

I'm not worried about the Earth. The Earth has been here a long time and endured many extinctions. Because that is what we are approaching, an extinction, and we will be the ones going extinct very soon if we don't change our ways. I'm worried about our survival.

Go see the movie if you haven't already, and then write your elected officials, buy a Prius, and put photovoltaic cells on your roof. That's what I feel like doing, at a bare minimum.

Go see it now!
