It would seem to me that current climate conditions at the time of birth would change survivability rates dynamically.

Higher survivability rates should equate to a higher ratio of females as they would subsequently reproduce the overall population in higher numbers.

I believe mammals (Great apes specifically) have a similar “quirk” where older male age and higher average calorie diets lead to more female births.
