<human>:  Why did the Ice Age end?
<bot>: The Ice Age ended when the Earth’s climate warmed due to the greenhouse effect. The greenhouse effect is caused by the greenhouse gases that are naturally present in the atmosphere, such as carbon dioxide and methane. The greenhouse effect is a natural process that helps regulate the Earth’s temperature. The Earth’s climate has been warming since the Industrial Revolution, and we are currently in an interglacial period of the Earth’s current ice age cycle.
