In 2010, a study suggested the coolest solution to global warming might also be the simplest ; a fresh coat of white paint could help cool the planet. The research examined whether painting city rooftops white could lower temperatures by reflecting more sunlight back into space. Scientists used computer models to estimate how this change could reduce urban heat and influence energy use in buildings. The study focused on the growing problem of rising temperatures in cities, where roads, rooftops, and other built surfaces trap heat. Researchers also explained that while the idea showed promise, more studies would be needed before it could be widely implemented.
