There's a proposal being put forth to stop the earth from over-heating. It comes from James Lovelock and Chris Rapley, two British scientists. It's just appeared as a letter to Nature. And I'm not the first blogger to take note.
The proposal is to use huge pipes to pump lower ocean water to the surface, thereby setting in motion (literally) a system that would absord CO2 and produce helpful atmospheric changes. Lovelock and his co-author assume that already it's too late for the ameliorating proposals of carbon emission control and such things to have any real affect. Thus they are now saying, "Help the Earth heal herself."
Lovelock is noted for helping popularize the nypothesis of Gaia, the planet Earth as a living organism in its own right. Not simply a collection of rocks, organisms, water and natural laws. And, in Gaia-talk, not a mechanism propelled by the will of a god or gods. Needless to say many fundamental religions do not have much truck with Lovelock. No wonder, the origin of Gaia is Greek mythology and a mother earth diety does not sit well with today's dominant patriarchal creeds.
That's a picture of Lovelock from his official website.
