| 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. |
|
| For over 30 years it's been thought that interglacials lasted about 10,000 years. |
|
| In between the ice ages, interglacials generally lasted about 10,000 years, which isn't long at all. |
|
| This then provides the opportunity for Milankovich cycles to become the pacemaker of the ice ages, causing alternating glacials and interglacials. |
|
| During interglacials, when sea level rose to approximately the present level, the Rhine built deltas, in what is now the Netherlands. |
|
| There is uncertainty over how much of Greenland was covered by ice during the previous and earlier interglacials. |
|
| The shorter and warmer intervals between glacials are referred to as interglacials. |
|
| The cycles in the isotope ratio were found to correspond to terrestrial evidence of glacials and interglacials. |
|
| These long glacial periods were separated by more temperate and shorter interglacials. |
|
| Floral and faunal remains of species pointing to temperate climate and indicating a specific age are used to identify particular interglacials. |
|
| The interglacials and glacials coincide with cyclic changes in the Earth's orbit. |
|
| Unlike the relatively mild interglacials driven by the tilt, wobble and orbit of the Earth, the PETM fundamentally transformed the planet. |
|
| It appears that even during interglacials the climate can oscillate between warm and cold, and yet the warm intervals are short-lived. |
|
| Earth did indeed plunge into an ice age about every 100,000 years, punctuated by warm spells, or interglacials, that lasted about 10,000 years. |
|
| More recent interglacials were only 10 000 to 20 000 years long and we're already 10 000 years into the current one. |
|
| The study says about 430,000 years ago, the glacial periods started to lengthen and interglacials started to shorten. |
|
| However, the scenario of cold, dry glacials, and warm, wet interglacials is rather too simplistic. |
|
| During interglacials, such as the present one, the climate warms and the tundra recedes polewards following the ice sheets. |
|
| Glacials, on the other hand, refer to colder phases within an ice age that separate interglacials. |
|
|
|
| Glaciation in the Pleistocene was a series of glacials and interglacials, stadials and interstadials, mirroring periodic changes in climate. |
|
| The colder periods are called glacial periods, the warmer periods interglacials, such as the Eemian Stage. |
|
| The glacials and interglacials also coincided with changes in Earth's orbit called Milankovitch cycles. |
|
| Extensive evidence now shows that a number of periods of growth and retreat of continental glaciers occurred during the ice age, called glacials and interglacials. |
|
| Despite the difficulties, analysis of ice core and ocean sediment cores has shown periods of glacials and interglacials over the past few million years. |
|
| Interglacials are identified on land or in shallow epicontinental seas by their paleontology. |
|
| Interglacials are a useful tool for geological mapping and also for anthropologists, as they can be used as a dating method for hominid fossils. |
