the technology was developed to preserve ski hills. That makes sense to me. Perserving the ice on Greenland...not so much. I know, I know, we're all going to die if the fertile soil under the ice of Greenland is actually exposed and useable again, but it's okay. I've had a good run.
A better and easier idea might be to deal with the fact that the ice on Greenland is melting. Maybe come up with a life plan that doesn't depend on Greenland remaining covered with ice. Besides, in reflecting the sunlight, and thereby the heat, from the surface of Greenland, you're just redirecting it back to the atmosphere, where it will travel to some other part of the world and "global warm" somebody else. Isn't that a politically correct no no?
