| In between the ice ages, interglacials generally lasted about 10,000 years, which isn't long at all. |
| The colder periods are called glacial periods, the warmer periods interglacials, such as the Eemian Stage. |
| For over 30 years it's been thought that interglacials lasted about 10,000 years. |
| Preceding and separating the cold glacial periods were three main interglacials when the climate was rather warmer. |
| These glaciers advanced during the four ice ages and retreated during the three interglacials. |
| This then provides the opportunity for Milankovich cycles to become the pacemaker of the ice ages, causing alternating glacials and interglacials. |
