Overview

• Over 84% of the world's coral reefs have been affected by bleaching, making this the most widespread event ever recorded, surpassing the 2014–2017 crisis.
• Record-high ocean temperatures, fueled by human-induced climate change, are the primary cause of this ongoing bleaching event that began in early 2023.
• Even previously resilient reef areas, such as Raja Ampat and the Gulf of Eilat, have succumbed to bleaching, signaling no safe havens remain for corals.
• Scientists report widespread coral mortality in regions including the Caribbean, Red Sea, and Great Barrier Reef, with some areas experiencing up to 90% coral death.
• Experts emphasize that immediate and substantial reductions in greenhouse gas emissions are critical to address the root cause of this crisis and protect remaining reefs.
