A series of giant pipes in the oceans to mix surface and deeper water
could be an emergency fix for the earth's damaged climate system, says
the scientist behind the Gaia hypothesis.
Professor
James Lovelock, whose hypothesis says earth is a kind of superorganism
composed of living and non-living elements, has fuelled controversy for
three decades.
He thinks the stakes are so high that radical solutions must be tried to fix our climate, even if they ultimately fail.
In a letter to the journal Nature,
he proposes vertical pipes 100 to 200 metres long and 10 metres wide be
placed in the sea, so that wave motion pumps up water and fertilises
algae on the surface.
This algal
bloom would push down carbon dioxide levels and also produce dimethyl
sulfide, helping to seed sunlight-reflecting clouds.
I always thought the point of the Gaia hypothesis was that the Earth is a self-regulating organism and humans should stop mucking with it. After all, it isn't the Earth that's being harmed by getting hotter or colder or whatever, it's people who would presumably suffer Gaia's revenge if their contributions to the atmosphere were considered undesirable by the superentity. Apparently Lovelock feels he has a special dispensation. Either that or he just can't keep his fingers out of the pie.
