Salt marshes humming with insects and birds. Mangrove forests with tangled, arching roots. Seagrass meadows that blanket the ocean floor. 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.

We’re dropping into your feed to share the news that our founding host, Laur Hesse Fisher, is departing MIT and TILclimate. In this episode, Laur sits down with new host Madison Goldberg to talk about the philosophies that have shaped TILclimate over seven seasons and take listeners behind the scenes of the show. They also discuss what’s in store for season eight—because TILclimate isn’t going anywhere.
