What If the Ice Age Never Happened?

Imagine Earth covered in thick sheets of ice and sea levels so low you could walk to a different continent. This is what our planet would look like during an ice age. There have been five of them in Earth’s history, and they have had a huge impact on our present world. Now, try and imagine an Earth where these ice ages never existed in the first place. What ecosystems would change? Would humans have evolved? Why do ice ages happen? What are Milankovitch cycles? Would there be climate change? How different would the season cycles be?
