I remember seeing pictures of that in my history books. Quite spectacular. [/QUOTE][img]graemlins/Funny_post.gif[/img] Just what are you trying to say?
Anyway, back to the topic, more or less, I was pointed to this article today, and what it has to say is rather interesting.

It was meant to refute something I had said there, and here, about the natural cycle, but, I find that it rather supports it. I've been taken to task twice about quoting interesting parts, even if I provide a link, but...

Over the last 400,000 years the natural upper limit of atmospheric CO2 concentrations was about 300 ppm. Today, CO2 concentrations worldwide average about 370 ppm. Humans may be able to take credit for some of these additions, but not all of them. Earth's plant life will respond to soak up these additions with additional biologic activity, but this takes time. Meanwhile perhaps up to 9% of CO2 concentrations in the atmosphere today may be attributable to human-related activities like agriculture, industry, and transportation. Compared to former geologic periods, concentrations of CO2 in our atmosphere are still very small and may not have a statistically measurable effect on global temperatures. For example, during the Ordovician Period 460 million years ago CO2 concentrations were 4400 ppm while temperatures then were about the same as they are today.

Interesting rebuttal. 9% attributable to humans. 9%... That's not a very large piece of the pie, now is it? The fact is, as I have stated from the very beginning, we do contribute. However, I don't know what we are supposed to do about the other 91%. I will say, however, that when sources are submitted by proponents, they are considered reputeable. So, since this is a reputeable source, it's nice to see what happens when science is actually applied. We aren't such the bad guys after all.
