    Back2Basics: Coral Reefs and Coral Bleaching

    coral

    • Corals are marine invertebrates that form colonies of polyps, which multiply and create reef structures.
    • Hard corals extract calcium carbonate to build hard exoskeletons, while soft corals add their skeletons to create coral reefs.
    • Corals have a mutually beneficial relationship with single-celled algae called zooxanthellae.
    • The zooxanthellae provide food and nutrients through photosynthesis, while corals provide a home and essential nutrients.
    • The zooxanthellae give corals their vibrant colors.

    Understanding Coral Bleaching

    • Causes of Bleaching: Environmental stressors like temperature changes, pollution, and high ocean acidity lead to coral bleaching.
    • Bleaching Process: Stressed corals expel the zooxanthellae, revealing their pale exoskeletons and disrupting the symbiotic relationship.
    • Impacts of Bleaching: Severe and prolonged bleaching events can result in coral death and the loss of biodiversity.

    Climate Change’s Impact on Coral Reefs

    • Warming Seas: Rising carbon emissions and greenhouse gases have caused increased global warming, resulting in warmer ocean temperatures.
    • Mass Bleaching: The frequency and intensity of mass bleaching events have risen in recent decades due to climate change.
    • Projections: Even with greenhouse gas reduction efforts, temperatures are expected to rise by 1.5°C to 2°C by the end of the century.

    Significance of Coral Reefs

    • Biodiversity Hotspots: Coral reefs support over 25% of marine biodiversity despite covering only 1% of the seafloor.
    • Economic Value: Reefs contribute $2.7 trillion annually through trade, tourism, and employment opportunities.
    • Environmental Protection: Coral reefs provide habitat and serve as a natural defense against storm waves.
    • Regeneration Potential: Dead reefs can recover if sufficient fish species graze on the weeds that settle on dead corals, although the process takes several years.
