Quote:If you pump 20 times the CO2 concentration in air, it will stay there untill it gets absorbed by the sea and 'eaten' by plants. This has two results, more plants (iof we don't destroy them again) and a more acidic sea.Well, unless there is another feedback system within the ocean which increases with carbonic acid (e.g. carbonic anhydrases in plants and algae), which I suspect would quickly convert into calcium carbonate, or some other solid carbonate compound useful for marine organisms. Measurable ocean Ph is rising, which means either the biological control (such as intense photosynthesis in the euphotic zone) lags the increase by some amount, or one sufficient large does not exist. Hopefully the mechanism for balancing ocean Ph will eventually balance the equation, since the planet has adapted to high CO2 levels before.
One of the problems in understanding the global carbon cycle is that you need doctoral degrees in astronomy, biology, chemistry, geology, oceanography, meteorology and maybe a few other sciences. And, I find in the debate on climate change, everyone is partial to their own field of study, whilst ignoring or discounting the other fields of study.
