El Niño, Heat Waves & the Future of Coral Reefs

<p>Coral reefs cover less than 1% of the ocean floor, yet they support a quarter of all marine life on Earth. So what happens when the water around them gets too hot to survive?</p><p>This year's strong El Niño is pushing already-stressed reefs past their limits. In this episode of <i>Atmosphere</i>, host Emily Gracey sits down with <b>Dr. Tracy Fanara</b>, an environmental engineer and ocean scientist, to break down what's actually happening inside a bleaching coral, why El Niño and climate change are attacking reefs from two directions at once, and a striking theory she's developed linking the 2023 bleaching event to a mysterious die-off of endangered small tooth sawfish.</p><p>Then Emily talks with <b>Shachar Damari</b>, co-founder of <b>V-Corals</b>, a Red Sea-based biotech company rethinking how reefs get rebuilt. Instead of the industry-standard method of cutting coral into genetically identical clones, his team works with a rare natural fusion event that combines multiple coral genotypes into a single, hardier colony.</p><p></p><p><b>What You'll Learn in This Episode:</b></p><ul><li><b>The Bleaching Process:</b> Why a "bleached" coral isn't a dead one, and what determines whether it bounces back.</li><li><b>A Two-Front Attack:</b> How long-term climate change and short-term El Niño patterns are compounding to hit reefs from both sides at once.</li><li><b>The Sawfish Mystery:</b> Tracy's leading hypothesis connecting reef collapse to a mass die-off of a critically endangered species.</li><li><b>The Restoration Problem:</b> Why most reef restoration doesn't hold up long-term, and what "resilience" actually requires.</li><li><b>A Different Approach:</b> How V-Corals uses a rare natural phenomenon, not genetic editing, to build coral that can survive future heat waves.</li></ul><p><b>Connect with the Show:</b></p><ul><li><b>Follow Emily on Facebook:</b> <a rel="noopener noreferrer nofollow" href="https://www.facebook.com/emilygraceyweather/" target="_blank">Meteorologist Emily Gracey</a></li><li><b>Follow the Show on Instagram:</b> <a rel="noopener noreferrer nofollow" href="https://www.instagram.com/atmospherepodcast/" target="_blank">@AtmospherePodcast</a></li><li><b>Deep Dive on Substack:</b> Subscribe to the <a rel="noopener noreferrer nofollow" href="https://atmospherepodcast.substack.com/" target="_blank"><i>Atmosphere</i> Substack</a> for weekly science breakdowns.</li><li><b>Listen to the </b><a rel="noopener noreferrer nofollow" href="https://www.youtube.com/@WeeklyWeatherBrief" target="_blank"><b>Weekly Weather Brief</b></a><b>:</b> Catch Emily and meteorologist Kerrin Jeromin every Friday for a quick rundown of the week's biggest science stories.</li></ul><p><b>Links:</b></p><p>Follow Dr. Tracy Fanara on Instagram- <a rel="noopener noreferrer nofollow" href="https://www.instagram.com/inspectorplanet/" target="_blank">@InspectorPlanet</a></p><p>V-Corals: <a rel="noopener noreferrer nofollow" href="https://www.v-corals.com/" target="_blank">https://www.v-corals.com/</a></p>
