The Florida Keys are facing a dire situation as rising sea temperatures trigger coral bleaching, prompting urgent action from restoration companies. This year's El Niño phenomenon, while potentially reducing hurricane activity, is also causing a heatwave in Florida's waters, endangering the region's coral reefs. The National Oceanic and Atmospheric Administration has issued an 'Alert Level 1' warning, indicating that water temperatures have reached a critical threshold. Coral bleaching, a process where corals expel the algae living within them, can lead to starvation and even death if temperatures remain too high for too long. The 2023 heatwave was devastating, turning coral nurseries into graveyards and pushing two species of coral to the brink of extinction. As temperatures continue to rise, restoration groups are scrambling to protect their coral brood. The Coral Reef Foundation has moved 246 corals to land-based facilities, while Reef Renewal USA is preparing to move 400 corals to their nursery. The fate of the largest corals, up to 45 inches across, hangs in the balance as they are expected to spawn in early August. These corals, already declared 'functionally extinct' in Florida, are in the most trouble. Despite the dire situation, scientists remain hopeful, citing the 2023 bleaching event as a learning opportunity. Restoration groups have adapted their strategies, and while the future is uncertain, their efforts provide a glimmer of hope for the survival of Florida's coral reefs.
