Rising temperatures turning turtles female

Rising temperatures are turning almost all green sea turtles in a Great Barrier Reef population female, new research has found.

The scientific paper warned the skewed ratio could threaten the population’s future.

Sea turtles are among species with temperature dependent sex-determination and the proportion of female hatchlings increases when nests are in warmer sands.

Tuesday’s paper, from the National Oceanic and Atmospheric Administration, California State University and Worldwide Fund for Nature Australia, is published in Current Biology. It examined two genetically distinct populations of turtles on the reef, finding the northern group of about 200,000 animals was overwhelmingly female.

While the southern population was 65%-69% female, females in the northern group accounted for 99.1% of juveniles, 99.8% of subadults and 86.8% of adults.



Okay, this is a pretty weird consequence of rising temperatures :O .

It sounds like a very serious issue, though :( . Is there anything we could do to protect them from this?

unless you take the eggs and hatch them in cooler sands then no there is not much we can do. with global temps rising it is causing a lot of adverse effects for many different aspects of the world and not just weather. sadly idk if much can even be done at this point.
