About this episode
Dr. Julie Simpson discusses the climate benefits of coastal saltwater wetlands.
The world’s coastal saltwater wetlands provide shelter for wildlife, purify water, and protect seaside infrastructure. And as Dr. Julie Simpson of MIT tells us, they also have a climate superpower: drawing down and locking away extraordinary amounts of planet-warming carbon dioxide.
