The International Coral Reef Initiative reports that 84% of the world's coral reefs are experiencing harmful bleaching, marking the most intense event in recorded history. This crisis, attributed to warming oceans, began in 2023 and surpasses previous bleaching events. Coral reefs, vital for biodiversity and coastal protection, are under severe threat, with scientists warning that inaction on climate change will lead to their demise. Conservation efforts are underway, but experts stress the need to reduce greenhouse gas emissions to effectively protect coral reefs.
