The primary impact of climate change on coral reefs includes increased ocean temperatures, leading to coral bleaching and compromised reef health. As global temperatures rise, corals expel the symbiotic algae (zooxanthellae) that provide them with food and color, resulting in diminished growth and increased vulnerability to disease. Additionally, ocean acidification alters the chemical composition of seawater, hindering coral calcification—the process crucial for reef structure. Protecting coral ecosystems is vital, as they support rich biodiversity and provide essential services to human communities.
