For years, the outlook for coral reefs has been increasingly bleak. Mass coral bleaching events caused by severe marine heatwaves have fueled repeated warnings that reefs are rapidly on an irreversible path of decline. But new research is challenging that narrative.
In a landmark study unveiled Tuesday, scientists have identified more than 64,000 square miles of coral reefs they believe have the potential to endure future warming. Spanning 71 countries and 100 territories, these resilient reefs make up roughly a third of the world’s reef systems.
“Coral reefs are often framed as ecosystems beyond saving,” said Emily Darling, a co-author of the study and director of coral reefs at the Wildlife Conservation Society. “Our research shows that there are three times more reefs that may be capable of surviving the climate crisis than previously thought.”
The research, known as the 50 Reefs+ study, includes a scientific paper and a detailed global map of some of the world’s most resilient reefs, created by SkyTruth, a technology nonprofit that uses satellite imagery and artificial intelligence to track environmental threats and protect biodiversity.
Using data from more than 45,000 coral field observations collected between 1960 and 2025, along with climate, oceanographic and human-impact data, researchers from the Wildlife Conservation Society and Macquarie University have produced the most detailed global assessment yet of coral reefs that show signs of being able to avoid, resist or recuperate from heat stress and other climate-related disturbances like cyclones.
“This is an important and encouraging contribution that reinforces our growing recognition that coral reef futures are not binary and that opportunities remain to identify and protect places where corals are most likely to survive and recover,” said Anne Cohen, a tenured scientist at the Woods Hole Oceanographic Institution , who was not involved in the 50 Reefs+ study.
The study builds on the original 50 Reefs assessment published in 2018, which provided the first overview of coral reefs most likely to withstand climate change. That initiative helped secure more than $100 million in funding dedicated to conserving these precious ecosystems.
The new analysis includes climate-resilient reefs across 30 additional countries and 54 territories and jurisdictions, highlighting a much broader range of reefs that can endure future warming.

More than half of these are concentrated in just five countries: Australia, the Bahamas, Cuba, Indonesia and the Philippines. Researchers also located areas of resilience in Belize, Panama and the Turks and Caicos Islands that were not captured in the original assessment.
In the Turks and Caicos Islands, the findings were met with both optimism and caution from Alizee Zimmermann , executive director of the Turks and Caicos Reef Fund, a non-government organization that works to protect the British overseas territory’s coral reefs.
“The narrative that Caribbean reefs are simply ‘dead’ is inaccurate and can be harmful to progress on reef restoration and protection initiatives in the region,” she said. “However, it would be equally disingenuous to say that they are thriving.”
Over the last few decades, Caribbean reefs have been devastated by heat stress, disease and increasing pressures from coastal development, boating and tourism. Despite these challenges, Zimmermann said, many reefs in Turks and Caicos continue to support diverse fish communities and show signs of recruiting new coral larvae.
Still, she said, there is a significant lack of long-term data about coral reefs there, which makes her curious to know how the study concluded Turks and Caicos hosts climate-resilient reefs.
“Knowing how data deficient our historic monitoring and datasets makes me cautious of such a broad claim,” she said. “I would be interested in having more information on the surveys conducted and ground-truth the predictions made in this study so that we can use them to drive meaningful conservation action.”

The study’s findings were presented at the Our Ocean Conference in Kenya , a global summit aimed at bringing together governments, scientists, conservation groups and business leaders to advance ocean protection efforts. The conference, being held June 16-18 in the coastal city of Mombasa, is expected to generate new commitments on marine conservation, sustainable fisheries and climate resilience, including those aimed at protecting climate resilient reefs.

Inside Climate NewsIndependentCenter4 days agoNew research suggests that more coral reefs may survive climate change than previously believed. A study identifies over 64,000 square miles of coral reefs across 71 countries and 100 territories that could potentially withstand future warming. The findings challenge earlier assumptions about the inevitable decline of coral reefs due to mass bleaching events.

OslobođenjeIndependentCenter5 days agoA new analysis of tens of thousands of research papers has identified areas across dozens of countries where coral reefs show greater resilience to rising ocean temperatures and other threats. Scientists have identified nearly 166,000 square kilometers of coral reefs believed capable of surviving and recovering from climate change impacts. This area is almost three times larger than previous estimates. Coral reefs represent one of the most important habitats in global oceans, providing homes for approximately a quarter of all marine life on Earth. In recent decades, these ecosystems have faced
