Climate change could affect reproduction in some animals.

Specifically, some animals – especially reptiles – have temperature dependent sex determination. In other words, the temperature leading up to some animals’ birth will determine if the offspring is male or female. Cold weather usually leads to more males, and warm weather leads to more females.

The worry is that this could lead to the extinction of some species as the planet continues to warm.
