It is heating, not cooling, which consumes the most energy in many places in the U.S., according to this article, "A White Roof Isn't Always the Right Roof"

By having information on the different roof choices, building owners can choose the roof that is best for their location and climate, and that best solution isn't always white.

Due to the overwhelming amount of heating degree days and positive winter heat gain in these locations, in all instances, energy consumption and carbon emissions are fewer with a dark roof surface than with a reflective surface. This is true even as far south as Albuquerque. It is also important to note that increased insulation dramatically reduces energy consumption in every model.

The media must be responsible when looking for ways to conserve energy and stop global warming.

(my bold emphasis)

White roofs are less energy efficient in about half of the U.S., while insulation is cost effective everywhere. Waste is a sin, and conserving energy is a very good idea, but only Mother Nature can stop, or start, global warming.
