| Term: | Interglacial |
| Definition: | A period of warm climate during the Pleistocene (and earlier glacial epochs) during which continental glaciers retreated to minimum extent. Interglacials have been of approximately 10 000 years duration, spaced at approximately 100 000-year intervals over the last 1 000 000 years. The last 10 000 years, or postglacial, is generally considered to be an interglacial. |
