Mike Pearl points to it:
A study published on Sunday in Nature Climate Change gave us the news that climate
change is bringing about a higher proportion of female sea turtles to males, thanks to a seemingly idiotic genetic quirk called temperature-dependent sex determination (TSD), also found in a few other species. Essentially TSD gives the turtles a baseline temperature of 84.2 degrees, at which there are 50/50 odds of being male or female. Beyond a certain threshold of heat, too few males will exist [to] the sustain the population. …
The authors of the study found that in the short term, turtle numbers are actually going to increase. The study looked at one species: loggerheads, on the island chain of Cape Verde off Africa’s west coast, and modeled what’s going to happen to them during 150 years of irrevocable temperature increase. The good news is that the increasing number of female turtles—who do the risky work of carrying the eggs to the island of their birth and laying them in hidden nests—will increase the overall number of turtles for the next 30 years.
