Global Warming Threats to Coral Bleaching Events and Their Impacts on Coastal Ecosystem Sustainability

The phenomenon of massive coral bleaching around the world is a black storm in coastal ecosystems this century. The annual increase in sea temperature by more than 1⁰C is a terrible fact that occurs due to global warming. There are many concerns raised especially on the cumulative impact of stress that corals experience when sea water temperature rise occurs. For this reason, this article is an intervention to reveal the high- level threat caused by global warming and the connection to coral bleaching events that disrupt coastal ecosystems. The literature study method in this article is useful to review and critically evaluate a number of articles that are closely related to support the fact of the urgency of coral bleaching in various countries. The great biological concern of coral bleaching that damages coastal ecosystems requires immediate mitigation and conservation, if it continues to degrade the number of coral populations significantly affects the decline in fish populations and biodiversity which affects the catch of fishermen and communities that have a major impact on coastal ecosystems. A good conservation strategy is expected to minimize the risk of damage so that it does not backfire on the chaos of coastal ecosystems in the future.
