GLOBAL CORAL BLEACHING EVENTS



Q: What is a global coral bleaching event?
A: It is a widespread phenomenon where corals expel the algae living within their tissues due to environmental stress, primarily from rising ocean temperatures. This causes corals to lose their color and become vulnerable to disease and death.

Q: Why is this the fourth global bleaching event?
A: Scientists have identified three previous events: 1998, 2010, and 2014-2017. The current event, declared in 2023, marks the fourth time such widespread bleaching has occurred.

Q: Why are bleaching events becoming more frequent?
A: The main cause is climate change, leading to rising ocean temperatures. Human activities like burning fossil fuels and deforestation contribute to greenhouse gas emissions, which trap heat and warm the planet.

Q: What are the consequences of coral bleaching?
A: Bleaching can lead to the death of coral reefs, devastating marine ecosystems and biodiversity. This also impacts fisheries, tourism, and coastal protection.

Q: Can coral reefs recover from bleaching?
A: Yes, but it takes time and depends on the severity and duration of the stress. Reducing greenhouse gas emissions and protecting coral reefs are crucial for their recovery.
