Coral bleaching is the process when corals become white due to loss of symbiotic algae and photosynthetic pigments. This loss of pigment can be caused by various stressors, such as changes in temperature, light, or nutrients.
Apr 17, 2024 · Corals can bleach in response to a range of threats, but today they most commonly do so because water temperatures are too high for them. And for more than a year, global sea-surface temperatures...

Apr 15, 2024 · On April 15, 2024, NOAA confirmed the world has been experiencing a global coral bleaching event. Bleaching-level heat stress, as remotely monitored and predicted by NOAA Coral Reef Watch (CRW), has been -- and continues to be -- extensive across the Atlantic, Pacific and Indian Ocean basins.
Coral bleaching is a phenomenon that occurs when corals lose their vibrant colors due to stress. A coral holobiont or coral for short, is essentially made up of an animal (polyp), symbiotic photosynthetic algae (zooxanthellae), and microorganisms (bacteria, archaea, fungi, and viruses).
By 2050, 90% of global coral reefs are projected to experience coral bleaching annually. Our planet’s rising temperature, combined with direct threats such as water pollution and overfishing, put stress on coral reefs.
