Hot Enough For You? Cooling The Worsening Urban Heat Island

As the globe warms, urban heat islands are projected to become more pronounced, with even hotter temperatures and a more stark urban-rural divide. But scientists and engineers have been working on solutions to reflect the sun before it can raise temperatures, such as cooler roofing materials and heat-reflecting pigments, cool pavements, green roofs, and neighborhood green space. This segment of the Science Friday program explores what is known about cool infrastructure, and how cities around the world are implementing solutions.
