Rising Temperatures
Ocean warming causes coral bleaching - corals expel symbiotic algae and lose their color, nutrition, and protection. Global temperatures have risen 1.1°C since pre-industrial times, triggering mass bleaching events worldwide.
Ocean Acidification
Increased CO2 absorption makes oceans more acidic, preventing corals from building calcium carbonate skeletons. Current pH has dropped 0.1 units, making it harder for reefs to grow and recover from damage.
Ecosystem Impact
Coral reefs support 25% of marine species. Their decline threatens fisheries, coastal protection, and biodiversity. Tourism and fishing industries lose $1 trillion annually from reef degradation.
Conservation Efforts
Scientists develop heat-resistant coral strains and restore damaged reefs. Marine protected areas limit fishing and pollution. Carbon reduction remains crucial for long-term reef survival. Shutdown123
