Wrong again! Well maybe not wrong ... just so incomplete as to be wrong. The amount of energy required to melt ice depends on the temperature of the ice. If the ice is close to its melting temperature very little energy is required. And as it melts, and exposes ground below it which is darker and more absorbant, more energy is absorbed leading to additional warming.

Are you incapable of getting anything right?
