Fair enough. Though, if the developed countries were far-sighted they'd probably agree to foot a hefty bill. Large portions of Europe/North America/Asia have a lot of coastline, its not just Africa/South America that would see dramatic climactic impact.

As for the feasibility, I imagine something like that would have to be ungodly large to appreciably impact the amount of solar radiation hitting the planet.

Sure... but the closer we get it to the Sun, the less huge it has to be. The idea wouldn't be to shade the world, but maybe a few less hours of sunlight hitting a few strategic spots on the planet might do something? I dunno... obviously I'm shooting from the hip, I just can't believe that there is
nothing we could ever do to try and slow/stop a warming earth, regardless of the causes of it. If it IS naturally occuring, and its going to keep rising... wouldn't we face possible annihlation/extinction? Shouldn't that be motivation enough to figure something out?
