So let me get this straight. You want to solve this problem by pouring iron powder into the oceans? Just how much iron powder do you think we'll need? That doesn't seem viable to me. It would deplete the world's iron supply.

Hawk, perhaps before your resort to name calling, you should reread your own articles, instead of asking me to reread them. Your own guy admits that decreased phytoplankton levels is due to pollution. What pollution do you think he's talking about? Below is a quote from your own article: "The Plankton would be increased or stimulated by putting large amounts or Iron Sulphate into the Ocean. This would actually not have any negative side effect on the oceans since we used to have a lot more plankton in the oceans two centuries ago then we do today. Again, this in large part due to pollution and Pollution induced climate changes." nowpublic.com Rising atmospheric CO2 and deliberate CO2 sequestration in the ocean change seawater carbonate chemistry in a similar way, lowering seawater pH, carbonate ion concentration and carbonate saturation state and increasing dissolved CO2 concentration. These changes affect marine plankton in various ways. On the organismal level, a moderate increase in CO2 facilitates photosynthetic carbon fixation of some phytoplankton groups. It also enhances the release of dissolved carbohydrates, most notably during the decline of nutrient-limited phytoplankton blooms. A decrease in the carbonate saturation state represses biogenic calcification of the predominant marine calcifying organisms, foraminifera and coccolithophorids. On the ecosystem level these responses influence phytoplankton species composition and succession, favouring algal species which predominantly rely on CO2 utilization. Increased phytoplankton exudation promotes particle aggregation and marine snow formation, enhancing the vertical flux of biogenic material. A decrease in calcification may affect the competitive advantage of calcifying organisms, with possible impacts on their distribution and abundance. On the biogeochemical level, biological responses to CO2 enrichment and the related changes in carbonate chemistry can strongly alter the cycling of carbon and other bio-active elements in the ocean. Both decreasing calcification and enhanced carbon overproduction due to release of extracellular carbohydrates have the potential to increase the CO2 storage capacity of the ocean. Although the significance of such biological responses to CO2 enrichment becomes increasingly evident, our ability to make reliable predictions of their future developments and to quantify their potential ecological and biogeochemical impacts is still in its infancy. sciencelinks.jp
