Hi Jim, I have yet to find the link to the program that shows the scientific data that proves humans are putting too much CO2 into the atmosphere. I am at work and the Discovery Channel website alone has enough to wade through. But it is the same data that the vast majority of scientists agree on that proves global warming is being influenced by humans. Influenced to the point where it is tipping the CO2 scales and causing global warming or exacerbating it. Now, one can either rummage through thousands of pages of scientific data or one can watch a one hour science program that tells you the same thing. And I have seen enough science programs and read enough about this to know when corporate entities are trying to dupe me. I will post the link when or if I can find it. Don, I do not see what the earlier epochs and periods of Earth history have to do with modern atmospheric data. In the carboniferous period, there were massive volcanoes too. That would indeed place a huge amount of CO2 and sulphur into the atmosphere. But there were also 3 foot diameter spiders and dragonflies with 3 foot wingspans. So what? I don't see your point. When volcanoes are going crazy... unlike today, you would expect massive influxes of these gases. Also, anyone can name a scientist or two that would agree with their views. Two or three scientists disagreeing with man-made global warming does not constitute evidence against the overwhelming data that says man-made global warming exists. That is like saying the fundamentalist Christians have refuted evolution because they can disprove the Java man fossils. It does not stand up against the overwhelming majority of collected data that says global warming is either caused or greatly exacerbated by humans. As far as attacking the messenger... when the messenger is the fossil fuel lobby, yes, I will attack it. I understand BP is trying to move in the direction of cleaner energy. But please, do not insult me by implying the petroleum industry and lobbyists are looking after the best interests of human kind. Profits off of fossil fuels are there biggest objective. And Exxon... come on. Every year they make billions in profits and still receive billions in tax breaks. Until the petroleum industry is willing to move part and parcel beyond technologies that have not changed for over one hundred years, I will rail against them. They are not my friends. Green energy is attainable and profitable. The fossil fuel industry has the ability to move us into cleaner energy sources. And so much more can be done by these corporate giants. But they want to wring out the very last drop of profit at our expense. And the very fact that we are discussing this makes me think that their propaganda has convinced some to think that we can keep using petroleum like it is going out of style. Well... you know what? It is going out of style... and quantity. The only question is... how much damage will we do to the Earth before we learn a very hard and serious lesson? By the way... I love this discussion. Jon
