Actually a new equilibrium will eventually be reached whereby part of the CO2 will remain in the atmosphere, part will increase the level of CO2 in the ocean. The amount of CO2 in vegetation, currently, is decreasing annually as deforestation occurs replacing carbon stored in trees with annual carbon in scrub or grass crops. > But the only thing that can change the ratio of CO2 in the atmosphere to > CO2 in the ocean, or CO2 in the ocean to CO2 in carbonate rocks, is a > temperature increase.

You can change the amount in each pool by dumping a large bolus of CO2 from a source that cannot be replaced into one of the pools. And the rate of uptake by the other pools can range from a few decades (for the upper ocean) to 6000 years or so for deep ocean to even longer for significant carbonate rock formation. > So adding 5.5 GtC That is 5.5 Gt of extra C per year, each and every year, right? > to the entire SYSTEM will have a very small effect on > the CO2 concentration in the atmosphere.

Actually the amount of CO2 put in the atmosphere during the course of the industrial revolution (or more recently) is sufficient that the atmospheric increase in CO2 should be twice what is observed. That means that half of anthropic CO2 is going to some sink somewhere. It is not going into land based sinks, since continued deforestation has increased the amount of atmospheric CO2 due to that source. That leaves, through the equilibrium of which you speak, the ocean as a sink, with the expectation that if the oceans are acting as the sink for the anthropogenic CO2, there will be a decrease in pH. Chemistry tells me that your explanation is pure bunkum. You are imagining that the atmospheric CO2 we know we are putting out through anthropogenic fossil fuel burning (and land use changes, namely deforestation) is somehow magically being replaced by CO2 from ocean carbonate rock and completely disappearing from the equation.

[snip] Your inability to read a simple graph is noted. http://www.woodfortrees.org/plot/esrl-co2/isolate:60/mean:12/scale:0.2/plot/gistemp/isolate:60/mean:12/from:1958 The cycles are not yearly. Still waiting for your theory on how the lagging co2 level causes a reversal in the temperature trend before hand.

Melted ice and rain dilute the oceans increasing thier solubility but increasing temperatures would reduce condensation. Please explain how there can be increased carbonate precipitation when the solution is at equilibrium.

As a reminder, you said "Raising the temperature of the earth will shift the equilibrium constants so that more CO2 enters the water..". CO2 is not a solid and more will not enter the water with increasing temperatures. |
