A note about Global Climate Change. In my opinion it’s not all our fault. I think we have managed to speed the process up, a lot, but the changing climate is normal. Just as you and I change as we age, so does the earth. Of course we last somewhere within a century, if we’re lucky, and the earth has aged over a few billion years, so the planet's changes are slower.
We, that is the inhabitants of earth, have been through a global climate change before. There was a time, about 20,000 years ago, when the room I’m sitting in was in the end portion of the Laurentide Ice Sheet. I’m combining what I remember from science classes with what I confirm with internet pages and Ice Age maps. I think it’s all pretty fascinating stuff. The ice sheet retreated and now ends somewhere near Greenland, much farther north. Why did the ice sheet retreat? There weren’t greenhouse gasses 20,000 years ago. So I think the Climate Change is a natural occurrence, pushed on a little faster by the earth’s greatest parasite; man.
What made the glaciers begin to retreat? Lots of evidence and theories about that. It wasn’t aerosol deodorant. It was natural. If it’s moving in that direction again, or perhaps still, and it’s moving faster, man may have something to with the faster part. I think it’s a sensible idea to take care of our earth. If we can slow Global Climate change even half as much as we’ve sped it up, it’ll help. And no matter what your belief system, it’s the most wonderfully unselfish gift you can pay forward to people you’ll never know; a place to call “home” for more generations.
