..... or a possible means of fixing more CO2 out of the atmosphere?
Following on from the iron filings idea, this from James Lovelock and Chris Rapley suggests building hundreds of thousands of massive vertical pipes in the oceans. Each pipe would have a one way valve at the bottom so that wave action near the top would draw nutrient rich water up from the ocean depths, providing a spur to more algal growth, which it turn will fix more CO2 from the atmosphere.
The full article is reported in New Scientist.
Just one little snaglet might be the fact that "as well as being rich in nutrients, water rising up the pipes will be rich in carbon - this could mean CO2 is released into the atmosphere."
Oh well, it sounded like a good idea at first.

Yes, I suppose they 'could'. But as mans's meddling with nature is not quite working out at a success rate that's enviable, maybe it's more down to whether they 'should'.

'Ah'll be barck'
It's spooky when a reader reads what you are reading at the same time, so I'll give Dave of Solarventi a credit, and as writer as well (saves me some RSI!):
A claimed method of direct CO2 extraction from the atmosphere using sorbents – don’t know if it could work on a massive scale but it certainly sounds interesting - http://www.gizmag.com/go/7341/
But when I thought about it for a few minutes, I became rather less enamored of the idea – I can’t help thinking that this sort of solution is perhaps akin to curing a consequential symptom rather than the underlying root cause?
I can see the headlines in a few years now – “Every house should have one! Erect your own CO2 absorbing tower in your garden and continue to fly, drive and burn carbon as much as you like!”
Couldn't agree more and, harking back to a blog on this subject many moons ago, I do recall the movie Total, er, Recall, starring one Arnie. S. Though in that flick it was for good, there is a powerful image at the end of solidified blocks of gas being released and changing the atmosphere in a moment. The towers in the pic even remind me of the movie.
Imagine a bunch of freeze-dried climate gunk suddenly deciding to erupt! I'm sure it couldn't happen, but....
