Ice reflects 50% to 60% of incoming solar heat. Albedo is part of the energy from the sunlight that casts back into the atmosphere. These rays have a significant effect on our climate. When the albedo rises, the universe reflects light more and consequently, higher levels of radiation are sent back to space so the Earth cools down.Abstract.

Wikipedia points out in this article about Bond Albedo; that Bond Albedo sometimes can be greater than Geometric Albedo, which apparently is the case with Venus and Mars. The other energy component—absorbed solar power is mainly determined by the Bond albedo. Regarding to the Bond albedo, we find the large difference between our study (0.503 ± 0.012) and the previous result (0.343 ± 0.032) by Hanel et al. 24.
