Climate change poses a severe threat to coral reefs, the diverse underwater ecosystems that support a wide array of marine life. Rising sea temperatures are causing a phenomenon known as coral bleaching, in which corals expel the colourful algae living in their tissues, turning them stark white. This weakens the corals and makes them more susceptible to disease. Additionally, ocean acidification, a consequence of increased carbon dioxide levels, inhibits the ability of corals to build their calcium carbonate skeletons.

 

As a result of these factors, coral reefs are facing widespread degradation. This not only has ecological implications, as it disrupts the intricate web of life that relies on these reefs, but it also has serious economic consequences for communities that depend on reef-related industries such as fishing and tourism.
