Most sea turtles are born as females due to global warming
Global warming not only causes climate change, but also has a major impact on various ecosystems. The National Ocean Service reports that female sea turtle populations have surged on some beaches due to intense heat waves caused by climate change.

According to the US National Oceanic Service, the sex of offspring born from sea turtle eggs changes with hatching temperature. If the eggs hatch below 27°C, they become males, and if they hatch above 31°C, they become females.
Due to climate change caused by global warming, severe heat waves have been reported in recent years in the summer, and 2022 will also be the year when record heat waves will be observed in various places. The state of Texas in the southern part of the United States recorded arecord high of 46.1 degrees, and deaths due to heat stroke have been reported one after another in various parts of the United States. The U.S. National Ocean Service believes that such an unusual level of heat wave has caused the sandy beach to become hot throughout the day, resulting in a higher proportion of females.
“As the planet experiences climate change, rising temperatures will bias hatching conditions and potentially even be lethal, affecting turtles and other animals,” said the National Ocean Service. said.
Bette Zirkelbach, manager of Turtle Hospital, an organization that protects sea turtles in Florida, said, ``Frighteningly, the last four summers in Florida have been record hot summers.We are studying sea turtle hatchlings and eggs. 'Scientists have found only female sea turtles and no male sea turtles in the last four years.'
Melissa Rosales Rodriguez, a keeper at Miami Zoo's Sea Turtle Hospital, said: ``The sea turtle population will plummet in the next few years because of the lack of genetic diversity. It is.”
