Record Coral Bleaching Event Threatens Global Reefs

An unprecedented 77% of the world's coral reefs are experiencing severe bleaching due to rising ocean temperatures.

More than three-quarters of coral reefs in the Atlantic, Pacific, and Indian Oceans are under thermal stress, linked to climate change.
This is the fourth global bleaching event since 1998, surpassing the previous record in half the time.
The bleaching results from corals expelling symbiotic algae due to high water temperatures, leading to potential coral death.
The Great Barrier Reef in Australia is experiencing its worst bleaching event, with over 70% of its reefs damaged.
Approximately 850 million people rely on coral reefs for food and income, highlighting the broader impact of this environmental crisis.
