Sea turtles laid a record 52,500 nests in Florida but 99% are female

• Sea turtle nests hit record highs in Florida this year, tripling last year's numbers.
• Most new turtles are girls, because a turtle's sex depends on the temperature they sit in as an egg.
• This is probably a symptom of climate change, and may spell disaster for future turtle populations.

Baby sea turtles are back in Florida in record numbers, but it's not time to celebrate just yet.

Almost 99% of new turtles are female, which means future generations could be in trouble, Joel Cohen, the director of communication at the Sea Turtle Preservation Society, told Insider.
