Rising temperatures and rainfall from climate change will have a surprising effect on human health, says biologist Erin Mordecai, an expert in diseases borne by mosquitoes, ticks and other living creatures. Such conditions are perfect breeding grounds for parasites that will bring deadly diseases to the U.S. and other places once thought out of reach. Hope may rest in mathematical models to guide smarter environmental policies, as Mordecai tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
