Guest: Victoria LudwigIntroduction: When the temperature heats up, people living in cities are often even hotter. That's because the parking lots, roads, and human activities in cities cause the urban heat island. Victoria Ludwig is the national program manager for the Heat Island Reduction Program at the US Environmental Protection Agency. She is here today to explain what urban heat islands are, how we can reduce them, and why the EPA is concerned. See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
