Coral reefs, essential to marine biodiversity, face severe threats from climate change. Increased ocean temperatures and acidification, driven by higher CO2 levels, lead to widespread coral bleaching and degradation. In Thailand, popular coral reefs, such as those in the Andaman Sea and the Gulf of Thailand, have experienced significant bleaching events, impacting marine life and local communities. Coral reefs support a vast array of marine life, but warming oceans cause corals to expel the algae they rely on for energy, leading to coral bleaching and eventual death if conditions don’t improve. Over the past few decades, significant coral cover has been lost globally, with estimates indicating that over half of the world’s reefs have degraded due to climate change, overfishing, and pollution. The loss of coral reefs not only affects marine ecosystems but also impacts coastal communities in Thailand that depend on them for food, tourism, and coastal protection.
