Almost all sea turtles born in Florida are female – Why? Climate change.

This article discusses the problem facing loggerhead and other sea turtles, caused by climate change heating up the beaches. Too hot sand? No males.

For more than a dozen years, the vast majority of sea turtles born on Florida beaches have been female, says Jeanette Wyneken, a biological sciences professor at Florida Atlantic University.

Not a single male loggerhead sea turtle hatchling was found at test beaches on the state’s Atlantic and Gulf coasts from 2015 through 2017, Wyneken said. And in the past 13 years, there have been seven years with no male loggerhead hatchlings.

It’s not just happening in Florida, either: About 99% of green sea turtles near adulthood and originating from the northern — and warmer —  part of the Great Barrier Reef were born female, according to a January study.
