 Coral reefs are highly sensitive to changes in water temperatures due to climate change. In 2019, a global bleaching event caused coral reefs around the world to lose their vibrant colors, known as coral bleaching. This study examined the effects of the bleaching event on coral reefs in Kaneo Bay, Hawaii. Researchers found that the algae living inside the coral polych changed in response to the bleaching event, with some species becoming more common, while others became less so. However, the overall composition of the algae remained relatively stable, suggesting that the coral reefs had adapted to the new environment. Additionally, researchers found that the coral reef's ability to survive the bleaching event depended on the depth and temperature of the area.
