«There is massive uncertainty in this figure, and until much more research is done no serious scientist should express any confidence in such estimates,» of iron fertilization's geoengineering potential, cautions oceanographer Richard Lampitt of the National Oceanography Center in England, who also argues that more research into such potential geoengineering techniques is needed due to the failure of global efforts to curb greenhouse gas emissions.
Therefore it's my opinion that the not - so - extreme decline from April to July 2010, coupled with the higher - than - usual April value, coupled with the changes (both trend and fluctuation) in both the size of and the timing of the annual cycle, are such that there's insufficient evidence to conclude that the Eyjafjallajökull eruption caused a noticeable change in atmospheric CO2, whether by emissions from the eruption, the lack of emissions from air traffic, or iron fertilization of the oceans.
