Note 1: the NAS study includes ocean
iron fertilization, which I haven't included in the above graphic because «
previous studies nearly all agree that deploying ocean
iron fertilization at climatically relevant levels poses risks that outweigh potential benefits.»
EFFECT OF NATURAL
IRON FERTILIZATION ON CARBON SEQUESTRATION IN THE SOUTHERN OCEAN Nature, Vol 446 26 April 2007 doi: 10.1038 / nature05700 The efficiency of fertilization, defined as the ratio of the carbon export to the amount of iron supplied, was at least ten times higher than previous estimates from short - term blooms induced by iron - addition experime
