Reducing the human-caused portion of global warming is a good idea... but it is far from being all we must do.  The process is irreversible... It can only be slowed to the point that we can catch up.

To catch up we must deal with the problems... dying crops from change in environment and flooding from rise of oceans.

I think the former won't be too hard in this day and age.  Surely we can build climate-controlled greenhouses for plants and we can genetically alter plants.

The latter... That's tough.  The worst case scenario: evacuate our most populous and richest cities and rebuild them from the ground up?!

I think that maybe we might be able to build a device that reflects sunlight from the polar ice caps... maybe.

Or how about this?  Water desalinization.  It's how Saudi Arabia gets most of its drinking water.

If we make a more efficient form of such machines, mass produce them and export them around the world...

This kills two birds with one stone.  It creates a water supply that is pretty much inexhaustable (the oceans)... and it creates an incentive to store lots of ocean water... Perhaps if used around the world, the ocean levels will drop enough that the melting polar ice caps will not flood us.


Maybe.  I'm really grasping here.
