Iron Fertililization Experiment Underway

my thoughts? bloody stupid idea! yes, just business trying to go for a quick buck, not thought  through at all, like the biofuels fiasco.

which kind of algae will bloom? what will that do to the ecosystem? how much will actually sink, and how much will stay sequestered? etc.

oh bother, new scientist has gone down. i got as far as search, the first article is the one i wanted to post;

Ocean seeding fails the acid test

Fertilising the ocean with iron filings to battle global warming also produces a nasty acid lethal to marine life and even humans

also found this summary;

Scientists Doubt Ocean Iron Fertilization as Climate Change Strategy

this wiki has some good looking references

Well the main controversy seems to be regarding whether this particular experiment is too large-scale.  Personally I'm okay with it because further experimentation will help to answer those questions raised by gerda.  The only issue is how large the experiments should be.

This just in yesterday:  LOHAFEX put on hold!

i heard warning bells a while ago, when i finally thought 'iron, red, red tide....errrr....what kind of bloom are we talking here.....'

News blurb in Nature on iron fertilization, contains reference to article appearing in same issue:

Yeah looks like bad news for iron fertilization.

A study published in this week’s issue of Nature (see page 577) finds that the potential of
iron-induced carbon sequestration is far lower than previously estimated.

Some think it is game over. “Ocean iron fertilization is simply no longer to be taken as a
viable option for mitigation of the CO2 problem,” says Hein de Baar, an oceanographer at the Royal Netherlands Institute for Sea Research in Texel.

On the one hand it's kind of disappointing that this process doesn't seem very viable for CO2 sequestration.  On the other hand, maybe it's a good thing, since there are concerns about other effects from the iron fertilization.

Yup, all that Grant Money right down the ole toilet. Another sparkling success for the MMCCKs. That's Man Made Climate Change Kooks for anyone that was wondering. :-)
