Dan and Andrew
I share Andrew's worry about oxygen depletion if there are too many
nutrients but I hope that because the sinks are moving oxygen-rich
surface water downwards and then letting it come part of the way up we
should be providing more.
I share Dan's concern about a network of

Thanks Ron.
That paper you mention from Intellectual Ventures Lab [1] has some
excellent arguments for geoengineering in general and for the Lab's
geoengineering design work in particular. For example:

Just a note that while pumping heat down into the ocean can lead to local
cooling, storing heat in the ocean is adding and retaining energy, so will
eventually emerge as warming. And, of course, it will contribute to sea
level rise. Thus, while a local effort of this type to help limit hurricane
Hi All
The oceans are a big thermal store so the scheme would give us time for
a quiet think. However we can bring nutrients up to the photic layers
and grow more phytoplankton giving more dimethyl sulphide for cloud
nuclei and converting lots of CO2 to non acidic biomass, some of which

Steve,
In talking to Dave Karl a few years ago who was testing Phil Kithil's tube,
it seemed like a core problem was trying to select for a depth where you had
more nutrients (P, N) than CO2, so there was a net gain... since carbon is
also greater at depth. Also-- Phil seemed to think he would
You're conflating two things Andrew, the limitation on growth and the
consequences (usually on heterotrophs) of its decomposition /
remineralization. Free oxygen is never limiting on photosynthesis, since it
is not consumed in the process, but rather produced.

I agree that this was an important interview for advancing
geoengineering (Fareed Zakaria is one of my favorite
writers/analysts/interviewers). My main objection was that Fareed or
his show producers seemed to not be aware of the limitations of SRM. By
this I mean that

Hello John et al,
Thank you, John, for drawing attention to the fascinating Nathan Myhrvold
interview. In my view the stratospheric seeding SRM scheme developed by Nathan,
Lowell Wood (both colossally brilliant and creative scientists) and others is
very likely to work effectively if
