Even if they're a long shots, I always feel a little high from the hope of climate engineering projects. I guess freezing new water on top of existing ice might also increae the ice albedo, in the case that it's covered in some amount of black carbon, plastics, or other pollutants? But that's probably less relevant in the (more isolated) polar regions.
