  2. Interglacial - Wikipedia

    en.wikipedia.org/wiki/Interglacial

    Interglacials are a useful tool for geological mapping and for anthropologists, as they can be used as a dating method for hominid fossils. [3] Brief periods of milder climate that occurred during the last glacial are called interstadials. Most, but not all, interstadials are shorter than interglacials.

  3. Stadial and interstadial - Wikipedia

    en.wikipedia.org/wiki/Stadial_and_interstadial

    Generally, stadials endure for a thousand years or less and interstadials for less than ten thousand years, and interglacials last for more than ten thousand and glacials for about one hundred thousand. For a period to be considered an interglacial, it changes from Arctic through sub-Arctic to boreal to temperate conditions and back again.

  4. Glacial period - Wikipedia

    en.wikipedia.org/wiki/Glacial_period

    Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. [1] The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. [2] [3] [4]

  5. Timeline of glaciation - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_glaciation

    During the last 3 Ma, ice sheets have also developed on the northern hemisphere. That phase is known as the Quaternary glaciation , and was marked by more or less extensive glaciation. They first appeared with a dominant frequency of 41,000 years, but after the Mid-Pleistocene Transition that changed to high-amplitude cycles, with an average ...

  6. Last Interglacial - Wikipedia

    en.wikipedia.org/wiki/Last_Interglacial

    The Last Interglacial was one of the warmest periods of the last 800,000 years, with temperatures comparable to and at times warmer (by up to on average 2 degrees Celsius) than the contemporary Holocene interglacial, [4] [5] with the maximum sea level being up to 6 to 9 metres higher than at present, with global ice volume likely also being ...

  7. Late Cenozoic Ice Age - Wikipedia

    en.wikipedia.org/wiki/Late_Cenozoic_Ice_Age

    The Eocene-Oligocene Boundary 33.9 million years ago was the transition from the last greenhouse period to the present icehouse climate. [ 17 ] [ 18 ] [ 10 ] At this point, when ~25% more of Antarctica's surface was above sea level and able to support land-based ice sheets relative to today, [ 19 ] CO 2 levels had dropped to 750 ppm. [ 20 ]

  9. Marine Isotope Stage 11 - Wikipedia

    en.wikipedia.org/wiki/Marine_Isotope_Stage_11

    Seemingly, the long-lasting interglacial conditions that are documented during MIS 11 depend on the peculiar interplay between CO 2 concentration and insolation. In fact, during periods of both eccentricity and precession minima, even small variations in total insolation might lead the control of climate to greenhouse gasses, in particular CO 2 .
