Great Barrier Reef Suffers Worst Bleaching Event in History

Australia's Great Barrier Reef is experiencing its worst mass bleaching event in history, with aerial surveys showing 90% of surveyed reefs exhibiting severe bleaching as ocean temperatures remain 2-3°C above normal.

The Crisis

Marine scientists report that 30% of affected corals have already died, with another 30% expected to perish if water temperatures don't drop within the next 4 weeks.

Long-Term Outlook

Scientists warn that the reef may not recover from this event, as bleaching intervals have shortened from once per decade to nearly annual, giving corals insufficient time to regenerate.

• 90% of surveyed reefs severely bleached
• 30% of corals already dead
• Ocean temperatures 2-3°C above normal
• Recovery increasingly unlikely
