Tidal wetlands are critical, yet vulnerable ecosystems. Tidal marshes, mangrove forests, and tidal flats support biodiversity, protect against flooding and storm surges, sequester carbon, and improve water quality. Due to human development and climate change, tidal wetland areas have been shrinking globally. A new study using 40 years of satellite data shows that this loss has been accelerating in the U.S. and that this acceleration is being increasingly driven by extreme weather events.
