Climate change is having a significant effect on one of the biggest green turtle populations in the world. A study shows that 99% of immature green turtles born in the northern part of Australia’s Great Barrier Reef are female. Among adult turtles, 87% are female. The result is 41 —rising temperatures have turned sea turtle population female. The sex of a sea turtle is 42 by the temperature of the nesting environment. Warm temperatures produce more female hatchlings, and cooler temperatures produce more males. During the past two decades, temperatures in northern Great Barrier Reef have increased to the point that virtually no male turtles are produced, 43 raises new concerns over the immediate threats of climate change to the population’s future. Sea turtles, protected under the Endangered Species Act, are among the most ancient species roaming the oceans and have adjusted to shifting climates. Increasing numbers of females may 44 be a good thing for its population. The reproductive potential can be boosted. The problem, however, is that the modern climate appears to be changing faster than turtles can adjust to it. Species evolve 45 climate and other environmental changes, but they need time for that. According to researchers of World Wildlife Fund Australia, setting up shade cloth to cool beaches might help, but the only sustainable solution is to stop climate change.
