  •  Your main problem -- (2+ / 0-)

    Merely mitigating climate change means not burning oil or coal -- which means not extracting it from the ground.  

    Think of what it would take to enact a global treaty to keep the grease in the ground.  It would have to be a bottom-up initiative -- the oil companies won't do it voluntarily.

    As for the algae, they're going to have to like the increased acidity that more atmospheric CO2 will bring.  At some point I am expecting the powers that be to erect a giant shield to block out the sun.

    •  But Corporations Being Citizens, Can We Approach (0+ / 0-)

      other top ownership not fundamentally wedded to grease to join in fighting big grease?

      Looking around the world, the bottom is not having a lot of success fighting the top unaided.

    •  More ocean acidification? Not necessarily. (0+ / 0-)

      Your point about algae and acidification of surface waters is well taken. However, it is based on the current notion of doing ocean fertilization and merely relying on the usual settling out of 25% of production into the depths as heavy debris (fecal pellets, shells).

      The trick is to pump the new production into the depths before very much of it can revert back into CO2 in the surface layer. Thanks to the 50-fold dilution factor (the wind-mixed layer is only 2% of ocean volume), the acidification problem is reduced.

      Furthermore, pumping down sinks the dissolved organic carbon of the surface waters, which has 240 times as much carbon as in the new algae.
