Temperature has a negative effect on male birthrates. A particularly good example is the sudden drop in male infant survival at the beginning of the Holocene, the increase in the world temp at that time went from The Younger Dryas period to what we have now, a difference of 18 degrees from present. It was a sudden change and mass extinctions occurred, the entire planet changed over night. (geologically speaking)
