In good news for coral reefs, scientists identify where the toughest ones are
Researchers identified nearly 166,000 sq km of coral reefs capable of surviving and recovering from climate change. These areas benefit from cooler currents and other favorable conditions. The data will help countries develop action plans for 30 by 30 conservation efforts.
What changed
New reports specify that cooler currents help protect these reefs and that the findings will inform 30 by 30 policy plans.

Global Study Finds 64,000 Square Miles of Climate-Resilient Coral Reefs
confidence 90%Researchers identified nearly 166,000 sq km of coral reefs capable of surviving and recovering from climate change. These areas benefit from cooler currents and other favorable conditions. The data will help countries develop action plans for 30 by 30 conservation efforts.
What's confirmed:
- Scientists identified nearly 166,000 sq km or 64,000 sq miles of coral reefs capable of surviving and recovering from climate change.
- The amount of resilient reef identified is three times higher than previous estimates.
- Cooler currents and favorable conditions help protect these corals from global warming.
Still unconfirmed:
- One-third of coral reefs may resist climate shocks.

Scientists pinpoint 64,000 sq mi of climate-resilient coral reefs across 71 countries
confidence 92%A global study confirms coral reefs spanning 64,000 square miles—three times earlier estimates—can survive or rebound from climate stress. These reefs, found in 71 countries, offer hope for restoration but still face long-term warming risks. Researchers urge protection to bolster degraded ecosystems, particularly in the Central Pacific. The findings strengthen calls for targeted conservation efforts.
What's confirmed:
- Coral reefs covering 64,000 square miles have been identified as capable of surviving or recovering from climate impacts.
- These resilient reefs are distributed across 71 countries, far exceeding prior estimates of such habitats.
- Protection of these reefs could aid restoration efforts, particularly in the Central Pacific region.
- Even the toughest corals remain vulnerable to sustained warming over the long term.
Still unconfirmed:
- A global analysis has mapped reefs with the greatest potential to withstand warmer temperatures, though specifics on methodology or regional breakdowns are not yet detailed.

Scientists pinpoint 64,000 sq miles of climate-resilient coral reefs
confidence 92%Researchers have identified vast stretches of coral reefs—spanning 64,000 square miles—capable of surviving or recovering from climate impacts. These reefs, found across 71 countries, triple earlier estimates of resilient coral habitats. Protection efforts could help restore degraded reefs in the Central Pacific. However, even these tougher corals face long-term risks from sustained warming.
What's confirmed:
- Scientists have mapped 64,000 square miles of coral reefs with the capacity to survive or recover from climate change impacts.
- These reefs are distributed across 71 countries, vastly exceeding earlier projections of resilient coral habitats.
- Researchers emphasize that protecting these areas could aid in repopulating degraded reefs, particularly in the Central Pacific.
- Artificial intelligence was used to detect sheltered reef pockets where corals are more likely to endure warming.
- Countries are advancing '30 by 30' protection plans, aiming to safeguard 30% of marine environments by the end of the decade.
Still unconfirmed:
- Some corals in the Red Sea endure heat stress but grow smaller and weaken over time, raising concerns about long-term survival even in resilient species.
- Advanced underwater robotics and cutting-edge research are being deployed in the Marshall Islands to study 'super reefs' resistant to rising ocean temperatures.
