Quote by: Sonart It's not about Human civilization, Spark. Anyone familiar with the hyperbolic curve knows that for 99.9% of human history, human population has remained consistantly small and our affect on the macro environment has been no more or less than othar species... even less in some cases.
It's only within that last 200 years or so that human population has exploded. But what people don't comprehend is that along with that population explosion, there's been a mirroring explosion in industrialization and our capacity to pillage and pollute the planet. |
I thought that part could be inferred from what I said, but I'm glad you clarified. Still, does anyone really expect our ancestors from even five hundred years back to have power plants burning fossil fuels 24/7? And we know that cars and railroads were not even part of society yet.

Quote by: xyzer CO2 is about 1% of the earths atmosphere |
If this is so, it can be argued that CO2 is just one proxy.

Quote by: xyzer we have had several decades of global cooling including the last 10 or so years? If it is a fact that humans have been spewing more CO2 into our atmosphere why is it cooling |
That's my only trouble with this whole global warming debate. Scientists disagree and then the results never seem to match up. Of course, there is a slight bias here that can explain some of that. After all, you want to focus on data that supports your position as we do here on this forum. And I know that it seems just so obvious (to either side), but if I were to take a much more detached point of view, I will really need to know which evidence to accept first. It is important to have this down before we make any inferences.

Quote by: xyzer If it is a fact that humans have been spewing more CO2 into our atmosphere why is it cooling??? Could something else be in control and the overwhelming influencer of warming and cooling? Could it just be the sun? Doesn't that make more sense? |
When you ask about the sun, are we now taking as given the assumption that the planet's atmosphere is warming? Moving on then... If the graphs from earlier are accurate, don't you see it as too much of a coincidence that the sun just happens to start playing a role the same moment humans begin to flood our planet with factories and autos? If the sun is involved, we probably did something in the last hundred years or so to make her mad like this.
