A new study from the Wildlife Conservation Society has mapped coral reefs across the Western Indian Ocean, revealing promising pockets of climate resilience that could reshape conservation efforts.
Using AI models and data from over 1,000 field studies, researchers offer a hopeful outlook for coral reefs, vital to marine biodiversity and human communities. Reefs support 25% of marine life, protect coastlines, and sustain millions through tourism and fisheries. Yet, coral bleaching and habitat loss pose significant threats.
"Past models have been coarse and often relied on just a few temperature variables," said Dr. Tim McClanahan, director of science for WCS's Global Marine Program in a statement. "Our model leverages the full capacity of global environmental mapping and machine learning, creating new possibilities for finding resilient reefs that need protection."
The study incorporates 35 environmental proxies, challenging previous models that predicted widespread coral decline under 2.7 degrees Fahrenheit warming. Instead, findings suggest up to 30% of global reefs may withstand rising temperatures, offering a more optimistic outlook.
Unlike traditional models focusing on temperature stress, researchers found that human activities — like resource extraction and water quality — often have a greater impact on reef health. This suggests that local conservation efforts, such as improving water quality and regulating fishing, could be more effective than previously thought.
However, urgent action is still needed. If global heating surpasses 2.7 degrees Fahrenheit without urgent carbon mitigation, only 15% of reefs may remain resilient.
"This means we should expect the more extreme model scenarios to emerge unless humans reduce greenhouse gas emissions now," Dr. McClanahan said in a statement.
By refining predictions and incorporating localized solutions, scientists hope to help conservationists prioritize effective interventions. This research aligns with broader marine conservation initiatives, including large-scale reef restoration projects and innovative coral farming techniques.
"As an early career scientist, understanding the complex interactions between climate change, human activities, and local conditions is crucial for informing targeted local conservation measures to protect and sustain coral reefs in a changing world," said Maxwell Azali, a co-author on the study in a statement.
