    Do dark surfaces exposed to the sun really contribute to global warming?

    Dark surfaces absorb more light while light surfaces reflect it. Extremely large areas of ice and snow reflect more light (and its energy) back into space than dark areas such as the ocean or ground that would be exposed if the ice and snow were to melt.
