Thanks, Claudia, for the wise words. We need to keep all our options on the table. I personally like wide-spread dispersal of ultramafics (alkaline minerals). It is good to remember that 99.99% of the earth is very alkaline (from metal oxides). The dangerously acidic part (from CO2) is only 0.01%--the outer skin of the earth a few kilometers thick. If a little of that alkaline part can be dispersed in land and waters, it will remove the CO2. We certainly need to find better ways to store energy.
