Okay, it seems balanced, or at least oscillating in the graph I found (Germany, but understandable world wide): http://www.biokurs.de/treibhaus/CO2-Dateien/petit.gif But HOW long was it 'balanced'? This graph goes back 400,000 years only. From the same source, there is a 600 million years overview: http://www.biokurs.de/treibhaus/CO2-Dateien/paleo4.gif Nothing seems 'balanced' in this time scale. In my opinion, most natural processes are not exactly an equilibrum. They change all the time - sometimes very slowly. For millions of years, dinosaurs and other animals died, producing coal and oil, maybe decreasing the CO2 concentration. Now, "they" come back. No equilibrum. Maybe an oscillation. Maybe a chaotic circle of carbon exchange between the gaseous and the solid part of the planet. > There are large underground fires but > if that is natural it may be about in balance with carbon being subducted.

So, the burning of our 7-10 billion tons of carbon is not the biggest part of CO2 emission, but it is "the last straw that breaks the camel's back"? The 600 million years graph I mentioned above gives a different picture: Temperature and CO2 levels are at their minimum. It is quite reasonable that the planet will increase both levels - with or without human interference. My question here: Is this graph based on robust data?

In a discussion, a friend of mine mentioned that the human contribution to the global CO2 emission is only very faint. I googled for his main argument and found out that underground coal fires are emitting huge amounts of CO2 - without filters or catalytic converters: http://www.aaas.org/news/releases/2003/0213fire.shtml If the human contribution to the global CO2 emission is really so faint, the Kyoto protocol and all other attempts of CO2 reduction would be ridiculous. Thus my question: Can anyone support or disprove it? Are there reliable quantifications? proellt
