"Liming the ocean" is a very interesting idea I had thought of but not seen published before. Idea is that dissolved CO2 reacts with alkali metals and precipitates out, raising pH and making atmospheric CO2 more soluble. Best place to do it is on cliffs and beaches where waves crash and stir things thoroughly. Putting iron compounds in ships' and overseas airliners' fuel would be useful too. The rabid reaction to that experiment, spreading iron dust, mystifies me. Winds off the Sahara dump thousands of tons of iron silicate dust in the south Atlantic and Mediterranean most years, naturally.
