According to a study by Florida State University, rising global temperatures are causing a gender imbalance. Scientists researched Brazilian loggerhead turtles and found that the warmer temperatures cause higher incubating temperatures, which leads to more female hatchlings.

Optimal hatching temperatures are between 75.2 to 93.2 degrees Fahrenheit, but temperatures below 85.1 degrees results in more male turtles and temperatures above yield more females.
