I think I will need you to tell me if this is the point:-
That the amount of CO2 produced naturally is often higher than previously thought.
That this means that the increase in CO2 could be due to other things than industry and fossil fuel use, although probably not.
That since there is this ability of geology to produce lots of CO2 then nature must be used to the occaisional increase in the stuff.
Is that right????
No, In this one area where there is high geothermal activity the estimated emissions were potentially skewed by the release of carbon by the geothermal vents. This is not evidence of all locations, but could be extrapolated to those areas with higher geothermal activity.
The level of the geothermal release was not indicating any natural emission factor upsetting the global calculations, but it was affecting the balance estiamtes of the locality.
Nature has handled a fairly significant portion of even the human released carbon, but that has started to affect the pH of the oceans and may be reaching the point where less and less can be natuatlly dealt with by the sinks.
