Will Ocean Fertilization To Remove Carbon Dioxide from the Atmosphere Work?

Reducing atmospheric carbon dioxide, a greenhouse gas linked to global warming, by fertilizing the oceans with iron may not be as attractive a solution as once thought according to a report in Science magazine.
In their observations released on April 4, Ken Buesseler of the Woods Hole Oceanographic Institution and Philip Boyd of the University of Otago in New Zealand report that iron fertilization as a means to “lock up” carbon in the oceans should be explored but note that the most basic question of “Will it work?” needs to be addressed before such a strategy is undertaken on a commercial scale.
