Climate change is posing a significant threat to sea turtle populations globally. Sea turtle sex is determined by incubation temperature, with warmer temperatures producing females. Rising global temperatures are leading to increasingly skewed sex ratios, with some regions now experiencing almost exclusively female hatchlings. This phenomenon, known as temperature-dependent sex determination, could severely impact the long-term viability of turtle populations by limiting genetic diversity and reproductive capacity. Scientists are concerned that a lack of male turtles will hinder breeding efforts and potentially lead to population declines. The situation highlights the urgent need to address climate change and explore potential mitigation strategies, such as shading nesting sites, to ensure the survival of these iconic marine creatures. Further research is underway to fully understand the extent of the impact and develop effective conservation measures.
