8 sustainability podcasts to listen to this Earth Day

When heat waves hit, people start looking for anything that might lower the temperature. One solution is right beneath our feet: pavement. Think about how hot the soles of your shoes can get when you’re walking on dark pavement or asphalt. A hot street isn’t just hot to touch – it also raises the surrounding air temperature. Research shows that building lighter-colored, more reflective roads has the potential to lower air temperatures by more than 2.5 degrees Fahrenheit (1.4 C) and, in the process, reduce the frequency of heat waves by 41% across U.S. cities. But reflective surfaces have to be used strategically – the wrong placement can actually heat up nearby buildings instead of cooling things down.
