The warm periods that occur between ice ages are called interglacial periods. These are characterized by higher temperatures, melting of ice, and a relatively stable climate compared to the colder ice age periods.
Periods occur as the lining of the uterus sheds in response to hormonal changes in the body. Each month, if an egg is not fertilized, the lining is no longer needed and is expelled through the vagina, resulting in menstruation. This cycle of shedding and renewing the lining of the uterus is what causes periods to occur.

Warm interglacial periods occur approximately every 100,000 years, alternating with colder glacial periods. These cycles are driven by variations in Earth's orbital parameters known as Milankovitch cycles. The most recent warm interglacial period we are currently in is called the Holocene epoch.
