Furthermore, the heat-trapping gases that we release in the most moderate scenario will warm the Earth for much longer than a typical interglacial
, on the order of 100,000 years.

In the medial segment of the OWC (Gorce Mts.), rates of dissection during successive interglacial
stages (Cromerian Complex through Eemian) increased from 0.12-0.14 mm/yr to 0.30-0.36 mm/yr (Olszak, 2009).
2002), others reflect a two-step event (called Zeifen-Kattegat oscillation), where warm conditions were interrupted by a cold dry oscillation preceding the Eemian Interglacial
(Seidenkrantz 1993; Seidenkrantz et al.
Here, fossilised giant clams, which lived during a 40 000-year-long interglacial
period known as Marine Isotope Stage 11 (MIS 11), can be found in ancient reef beds uplifted by geological processes to some 1200 metres above sea level.
Beyond that, recent advances in luminescence and uranium series methods are beginning to provide the basis of a robust chronology in terrestrial sequences back to the Last Interglacial
The role of the ocean in providing heat to high latitudes during deglacial and interglacial
times may be crucial in prolonging interglacials
and making them more extreme.
In order to quantify the climate differences associated with the variable interglacial
intensities, four warm phases were investigated in detail: the two youngest, "normal" interglacials
, since 12,000 years and about 125,000 years ago, and two of the "super" interglacials
, about 400,000 and about 1.1 million years ago.
The deposits palynologically studied in two reference sections (Otkaznoe and Strelitsa) refer to one of the warmest interglacials
of the past half-million years.
Broecker also points out that loess, which was generated in copious amounts during the peaks of the glacial periods, wasn't produced during interglacials
