Rising Temperatures Cause Sea Turtles to Turn Female

Warming temperatures off the coasts of Australia may be having a devastating effect on green sea turtle populations by turning almost all their offspring into females. Sex in sea turtles is determined by the heat of the sand the eggs incubate in. As temperatures rise due to climate change, more and more females are being born. On Raine Island, the Pacific Ocean's largest and most important green sea turtle rookery scientists found that female sea turtles now outnumber males 116 to 1. Raine appears to have been producing almost exclusively females for at least 20 years. It's unclear how turtles are affected worldwide, and other factors like habitat changes may play a role in shifting sex ratios.
