Quote:1. The start of the growth in CO2 concentration coincides with the start of the industrial revolution, hence anthropogenic;
2. Increase in CO2 concentration over the long term almost exactly correlates with cumulative anthropogenic emissions, hence anthropogenic;
3. Annual CO2 concentration growth is less than Annual CO2 emissions, hence anthropogenic;
4. Declining C14 ratio indicates the source is very old, hence fossil fuel or volcanic (ie, not oceanic outgassing or a recent biological source);
5. Declining C13 ratio indicates a biological source, hence not volcanic;
6. Declining O2 concentration indicate combustion, hence not volcanic;
7. Partial pressure of CO2 in the ocean is increasing, hence not oceanic outgassing;
8. Measured CO2 emissions from all (surface and beneath the sea) volcanoes are one-hundredth of anthropogenic CO2 emissions; hence not volcanic;
9. Known changes in biomass too small by a factor of 10, hence not deforestation; and
10. Known changes of CO2 concentration with temperature are too small by a factor of 10, hence not ocean outgassing.

Thanks. That's one of the things I'm looking for. This is the site I've been reading: http://www.justfacts.com/globalwarming.asp
I've also been listening to a series of lectures on audiobook. Yay YouTube! Link: http://youtu.be/5uJVkmqHIHg
