Great Maurice! We are converging on agreement on matters of fact. Yes, Co2 would have increased far more if all released stayed in the atmosphere. The oceans absorb quite a bit of it. The vast majority of this stays in the upper layers, and forms another reservoir with a slower turn over time than atmosphere. It would be good if we could stimulate export of carbon to the abyssal depths, where turn-over would be so low as to be considered a true sink. Work has been done on fertilizing the ocean with iron to see if this might help. A problem with all fertilisation is that plants need many nutrients. Add one thing that is limiting and it is likely that something else will limit growth. In your greenhouses, the plants have all the nutrients they need. The CO2 effect also depends on the particular plant. Apparently sour oranges do particularly well on enhanced Co2. There all sorts of effects of enhanced Co2. Tim pointed out that if there is warming, this could cause a huge 'burb' from northern soils. (Sorry poleward, but most of this happens to be in the N hemisphere.) This more than makes up for the longer growing season in warmer climate that would increase sequestration. There is also the change in the distribution of rainfall. It's possible that all these effects will cancel out. Are you a betting man? It's interesting that you are using BP's data. I believe they are on record as saying that global change is a challenge and that emissions should be curbed! PS. Did you see my post on Ramsey's thread suggesting that CDMA might have attractions for the govt. of China that should irk libertarians and liberals alike?
