Indonesia's coral reefs demonstrate heat tolerance, though stability remains limited by critical thermal thresholds.
Long-term research covering 2004-2023 across 394 sites shows most reefs maintained stable coral cover despite rising temperatures.
A critical tipping point for coral loss was identified at 12 degree-heating weeks, marking the limit of heat absorption.
Effective local reef management, including marine protected areas, is essential to assist recovery following severe bleaching events.
