As the world bakes in brutal historic heat, painting your roof white may be a way of cooling off Earth. Jon Parker of American Home Contractors in New Jersey says painting a roof white can cut air conditioning bills by reflecting the sun's rays. To try to tackle climate change, a team of scientists at Purdue University developed an ultra-white paint that is officially recognized as the whitest paint ever made. Scientists say it can reflect 98% of the sun's rays.
