珊瑚白化 厄尔尼诺气候变化对泰国鹿角珊瑚的影响

valley coral or Brain coral (Platygyra daedalea) displays coral bleaching across half its colony, pale zooxanthellae-depleted tissue contrasting with healthy living coral in a single frame documenting climate change impact on an Andaman Sea reef. Bleaching occurs when elevated sea temperatures cause corals to expel symbiotic algae, cutting their primary energy source. With an El Nino event projected for 2026, thermal stress across the Indo-Pacific is set to intensify. Ko Haa, 4K, vertical medium shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
