"The ocean might just get more disolved CO2 as we emit more" Nope. The cycle time for bottom water is measured in centuries. The problem is that the warmer the water, the less dissolved gasses it holds. If the transports gets messed with, and the La Nina and El Nino are signs that the transports aren't working like they used to, then unpredictable things happen. Some of the increase in cloudiness is going to be counterbalanced, ironically, in that we burn our carbon more efficiently, there is less smoke and SO2. The concerns over the start of another ice age were based on the assumption that we are in the middle of a inter-glacial period. There was no real objective proof of that, in fact even then the worldwide retreat of the glaciers were evident. Now that we know exactly how fast they are retreating (well most are, anyway) I don't think that anyone would seriously argue that a new ice age is imminent. The only model I've seen recently that suggests that possibility involves the melting of the Artic ice cap and the abrupt change of ocean currents. This doesn't help support the "CO2 is our friend" argument. Iron enrichment in the polar seas has been tried. It stimulates phytoplankton production as expected, although it is hard to measure exactly how much because of dilution. Ideally, you would combine this with sea farming, it seems to go hand in hand.
