"CO2 I believe is of consequence NOT cause of warming.". Well, if you wont accept one of the most well established facts of this subject, that the rise of CO2 concentration in the atmosphere is due to our activities, there isn't much that I can say to convince you.

The CO2 in trees came from the atmosphere, the CO2 in fossil fuels has been locked away, not involved in the carbon cycle for million of years. So, while chopping trees does add some CO2 (or recycles it quicker), the far greater problem is fossil fuel burning which adds CO2. It the fossil fuel CO2 that's ancient.

Source please. I have to say it looks like pretty duff stuff to me. Re the first point. Suppose you have a bath. Every hour you have 90 litres running in and 90 litres being pumped out. OK, the level stays the same. What happens if you add in an extra 6 litres per hour every hour? yes, it fills up. The point is both natural emission AND sinks of CO2 are vast but effectively (until we peturbed the CO2 cycle) IN BALANCE. But we are adding extra CO2, so that now the atmosphere concentration of CO2 is a third more than it was. Try http://illconsidered.blogspot.com/2006/03/...arf-humans.html There is a lot less methane - think about it! Oh, and I'd find out the difference between weather and climate if I were you. I suggest you work your way through the answers here - http://illconsidered.blogspot.com/

Frankly, it's just not even possible that volcanoes are responsible for the increase in CO2. Firstly, if you do the sums they show such a claim makes no sense - http://illconsidered.blogspot.com/2006/02/...t-more-co2.html , secondly you can show, by the way the isotopic signiture of atmospheric CO2 has changed, that the extra CO2 is due to our activities. Re past CO2 concentrations, you can't compare then with now. CO2 is a climate forcing, but, if you change the continents so they alter ocean currents (as they did at times in the past) that can profoundly effect world temperatures. However, that was then, this is now, you just can compare the distant past with now.
