Again, let's posit that somebody pulls off sulphate injection and it works, "works" defined as holding down global surface temperatures. Woo-hoo - Fossil Party Time!

Except that it wouldn't be. Under Extended BAU, the same ratio of atmospheric vs. marine carbon continues apace, further speeding acidification, ending fisheries and reefs and (eventually) eliminating the single biggest source of planetary oxygen.

What then for the Last Best Hope Of Earth?
