Coral Resilience Amid Climate Change
Coral reefs face significant threats from climate change, with projections estimating that warming of 1.5 to 2 degrees Celsius could lead to a dramatic decline in coral populations. However, recent studies suggest that some coral species may possess the ability to adapt to hotter and more acidic ocean conditions. Researchers in Hawaii conducted experiments showing that while coral growth rates declined under stress, all tested species survived and displayed remarkable adaptability. The findings indicate that, under a low climate change scenario, coral reefs can still have a viable future, underscoring the critical importance of global emissions reductions to protect these ecosystems.
