Interglacial

A hot time in the climatic history and also in geology neutral a period with higher average temperatures between two time periods with lower average temperatures, so-called cold periods. Is a warm period within an ice age meant, so one speaks also of interglacial or interglacial, more rarely of interglacial period. Longer periods of Earth's history with an above-average high temperatures ( about the length of earth periods ) are also referred to as a warm climate. In times of Warmklimata there is on earth usually no larger icing conditions, especially not in the polar regions. To explicitly express this climate condition, no icing conditions on earth, even the term akryogenes hot air is being used.

Ice Age

Ice-free polar caps provide geological represents the normal state and account for about 80 to 90 percent of the earth's from. One example is the Paleogene ( older Tertiary). Times with polar ice caps, the ice age, so-called, are rare exceptions hold the product geological period, the Quaternary, is one such ice age.

Interglacials within an ice age

The term warm period is the same as Ice Age blurred. We therefore speak of better interglacial period ( interglacial ). An interglacial can be considered as mittelskalige climate fluctuation of about 10,000 to 400,000 years. The Holocene, which continues to this day, is such a warm period within the - seen in longer periods of time - the current ice age, the Pleistocene ice age.

The last major interglacial periods ( within the meaning of interglacial period ) were:

  • Eemian interglacial period with a duration of 11,000 years; 128000-117000 years ago today
  • Holstein interglacial ( warm period also Saale ) 335000-300000 JVH
  • Cromer interglacial period 800000-480000 JVH
  • Waal - interglacial 1300000-900000 JVH
  • Tiglian warm period 2000000-1600000 JVH

Interstadials

By analyzing the oxygen isotope curve of 18O from drilling in deep-sea sediments and ice cores can now come to geologically small-scale climate variability, the interstadials. The corresponding data is improving, the more one approaches the present. An interstadial has an average duration of a few hundred to a few thousand years.
