Explore the latest, uncharted realms of ocean science and conservation that you won't find anywhere else. Andrew takes you on an inspiring journey to uncover the hidden gems of oceanic discovery and initiatives. Tune in to discover how you can transform your life for a better ocean, one episode at a time. The How To Protect The Ocean is your resource to keep you informed on the latest ocean news; teach you how to speak up for the ocean; and, how you can take action to live for a better ocean. There is so much information on the ocean and the issues that are affecting it that it can be difficult to find optimism in the future of the ocean. Climate change, overfishing, plastic pollution, water pollution, and coastal development have altered the ocean in ways that have negatively changed the way we use it. The repercussions of climate change, including the ominous specter of rising sea levels, the relentless march of warming ocean temperatures, and the ominous shadow of ocean acidification, have not only altered the very fabric of our coastlines but have also conjured fie…","last_synced_at":"2026-09-26T08:23:21.814007+00:00","page_url":"https://stenobird.com/podcast/how-to-protect-the-ocean-2010"},"episode":{"title":"Millimeters That Matter: The Sea Level Rise Threshold Coastal Wetlands Can't Survive","slug":"millimeters-that-matter-the-sea-level-rise-threshold-coastal-wetlands-can-t-survive","published_at":"2026-09-17T23:01:00+00:00","page_url":"https://stenobird.com/podcast/how-to-protect-the-ocean-2010/millimeters-that-matter-the-sea-level-rise-threshold-coastal-wetlands-can-t-survive","show_page_url":"https://stenobird.com/podcast/how-to-protect-the-ocean-2010","url":"https://www.speakupforblue.com/podcast","audio_url":"https://traffic.libsyn.com/secure/scicon/HTPTO_E2025_MangrovesOnTheMove.mp3?dest-id=228444","summary":"Sea level rise. It's a phrase everyone's supposed to be afraid of, and almost nobody can picture. A couple of millimeters a year sounds too small to matter, until you find out coastal wetlands have an exact, measured speed limit for how fast they can keep up, and the ocean is closing in on it. Marshes and mangroves have kept pace with a rising sea for thousands of years by building their own soil upward, layer by layer, as plants grow, die, and get buried in place. That strategy has a hard limit. Peer-reviewed research puts it at roughly 6.1 millimeters of sea level rise a year, the point past which soil simply can't build fast enough. NASA's own sea level data shows the global rate has already gone from about 2 millimeters a year in the early 1990s to roughly 4.5 millimeters a year today, nearly doubling in three decades and closing that gap fast. There's a second strategy, and it's already working in real places. When a marsh can't out-build the tide, it can move inland instead, if there's room. Maryland's Blackwater National Wildlife Refuge has lost more than 5,000 acres of marsh, nearly half its historic wetland, and faces up to three feet of sea level rise in the Chesapeake by 2100. Its 2013 Blackwater 2100 strategy uses conservation easements to pay landowners to keep migration corridors open, and it's already protected more than 3,000 acres along the Nanticoke River and Coursey Creek. This episode connects back to Monday's interview with Dr. Adam Langley and lands on what coastal communities can actually do about it. Takeaways: Marshes and mangroves survive sea level rise by building soil upward, but that strategy has a hard limit: peer-reviewed research (Saintilan et al., 2020, Science ) puts it at roughly 6.1 millimeters of sea level rise a year.
