Huge pipes in the middle of the ocean

James Lovelock – of Gaia hypothesis fame – has recently proposed using "millions of vertical pipes across the oceans to pump nutrient-rich deep water to the surface." This would "fertilise the growth of algae, which in turn [would] fix carbon dioxide" – thus helping to assuage the effects of industrial air pollution, reducing global warming.
"The pipes," we read, "reaching to depths of 200 metres, would have flap valves at the bottom operated by the energy of waves, which would push deep water up the pipe."
The future of architecture lies in weather control.

Lovelock's idea was apparently inspired by a New Mexican company called Atmocean. Atmocean suggested last year that "100 million 10-metre diameter pumps across the oceans could capture one-quarter of human-made CO2 emissions."
From Atmocean's website:

When fully deployed, our 3m diameter by 200m deep pumps spaced 2 km apart will be positioned across 80% of the world’s oceans. A single pump consists of a buoy, flexible tube, valve assembly, cable between the buoy and cylinder, and solar panel to power communications & remote control. Pumps are connected one-to-the-next at the base 200 meters deep, forming large arrays which maintain position from the sea-anchor effect. The pumps self-deploy when dropped into the ocean from barges. Arrays will be deployed outside of the 200 mile territorial limit to avoid busy shipping lanes.

Those pipes – a "proprietary wave-driven ocean upwelling system" – might also reduce hurricane intensity.
The problem, however, is that this strategy might also release carbon dioxide into the atmosphere, making global warming substantially worse.
But screw it: I say let's do it. It sounds fun. Huge, self-deploying pipes in the middle of the ocean? We could station poets there and publish their work as part of a national literary undertaking in one hundred years' time, offering stipends to 19-year olds willing to risk the oceanic loneliness. Stanzas at Sea.
