How the weather is making 99 percent of these baby sea turtles female.

Green sea turtles do not develop into males or females due to sex chromosomes, like humans and most other mammals do. Instead, the temperature outside a turtle egg influences the sex of the growing embryo. And this unusual biological quirk, scientists say, endangers their future in a warmer world.

Already, some sea turtle populations are so skewed by heat that the young reptiles are almost entirely female, according to a new report in the journal Current Biology.
