This square design centers on a four-panel infographic from the Great Barrier Reef Foundation, via the BBC. The headline says, “Four Stages of Reef: What causes coral bleaching? At upper left is “Healthy: Coral and algae depend on each other to survive. If the environment is right, they both thrive.” Upper right: “Stressed: Multiple factors including a change in ocean temperature, pollution, and too much sunlight can cause algae to leave the coral’s tissue.” Lower left: “Bleached: Without algae, coral loses its major source of food, turning it white or very pale and leaving it at risk of disease.” Lower Right: “Dead: If factors change then a bleached coral can revive, but it takes years. If not, the vital ecosystems can ultimately die.”
Between August ’24 and May ’25 the worst bleaching on record hit the world-famous coral 🪸 reefs along the Western Australia 🇦🇺 coast. Globally 2024 was the #hottest #year on record. 2023 and 2025 are tied for second.
