As Florida anticipates another hot summer, scientists are ramping up coral restoration efforts to combat the severe decline of coral reefs. With sea temperatures reaching 97°F, fears of mass bleaching are rising, following last year's record event. Restoration initiatives include selective breeding of heat-tolerant corals and the 'Rescue a Reef' program.
- 01Sea surface temperatures in Florida Bay have reached 97°F, raising concerns about coral bleaching.
- 02The summer of 2023 recorded the worst coral bleaching event in South Florida's history.
- 03Researchers are developing heat-tolerant coral strains through selective breeding, including fragments from Honduras.
- 04The 'Rescue a Reef' program has restored approximately 2,000 corals over the last decade.
- 05Coral cover in Florida has declined by over 90% since the 1970s due to various stressors.

Florida's coral reefs are facing an unprecedented crisis as scientists and volunteers intensify restoration efforts in anticipation of another scorching summer. Recent measurements indicate sea surface temperatures in parts of Florida Bay have soared to 97°F, raising alarms about potential mass bleaching events. This follows the summer of 2023, which was marked by the worst coral bleaching event in South Florida history. While federal officials have yet to report widespread bleaching this season, early signs are emerging, particularly near Miami, where 25% of corals near PortMiami have shown bleaching. To address the ongoing decline, researchers are employing selective breeding techniques to create heat-tolerant coral strains. A pilot project involves reviving the endangered elkhorn coral by crossbreeding resilient strains from Honduras with local varieties. Additionally, the 'Rescue a Reef' program has successfully restored around 2,000 corals over the past decade. Despite these efforts, scientists warn that localized restoration cannot fully counteract the long-term damage caused by climate change, pollution, and other stressors affecting Florida's reefs.
