  Not quite.  The studies show that it is possible to produce a
short term, limited area, increase in ocean productivity.  It
is deemed likely in that field that the term and area could be
extended considerably.  What they do not show, yet, is that
the increase in productivity is sufficient, and of the nature,
to substantially change the air-sea transfers of CO2.  They are
further from showing that the changes are such as to permanently
remove CO2 from the atmosphere.  They are even further from showing
that the amount of CO2 which can be removed is comparable to the
amount which is being added to the atmosphere.

  It is very interesting research.  There is even some promise
for geoengineering to be derived from it.  The work, however, is
far from the stage of being a technology to implement at whim.
