For the SciFri Book Club, Marcelo Ardon, ecologist at NC State University, and Letitia Grenier, co-director of the Resilient Landscapes Program at San Francisco Estuary Institute, joined us to discuss the effects we are already seeing in coastal wetlands from climate change, and how restoring ecosystems might make an impact. Plus, what exactly is the difference between a tidal wetland and a saltwater marsh? Come for the collaborative ways experts are working together to address sea level rise head-on; leave with ideas for activating change in your community, no matter where you live. --- Because of the pandemic, our show is currently pre-recorded, so the #SciFri​​ team have not able to take our audience's calls. We miss having listeners' voices on our radio program. We still want to hear from folks on our VoxPop app, but we're also experimenting with something new—we’re inviting our listeners to join us live for select recordings for #ScienceFriday​​ on the radio! The event was recorded on Tuesday, October 5, 2021. The segment airs on the radio and our podcast on Friday, October 15, 2021. If you'd like to join future live Zoom call-ins to get your questions on the air with us, sign up for updates at https://www.sciencefriday.com/articles/join-live-recording-online/
