If we switch quickly from fossil fuels, climates might come to resemble those of the interglacial
warm periods that punctuated ice ages of the last two million years.
Introduction: Climate, vegetation and mammalian fauna in Europe during Middle Pleistocene interglacials
(MIS 7, 9, 11).
Also, the researchers report, interglacial
periods between 800,000 and 400,000 years ago weren't as warm as those that have occurred more recently.
In order to reconstruct the climate of past interglacial
periods, she had visited Henderson Island, in the far south-eastern Pacific Ocean, to collect 330 000- and 630 000-year-old fossil corals for climate studies.
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

Modeling the Past and Future Interglacials
in Response to The Astronomical and Greenhouse Gas Forcing
Before the MPT, the alternation between glacial periods of extreme cold, and warmer interglacials
, happened at intervals of approximately 41,000 years.
eight glacial epochs (Pokrovka, Devitsa, Don, Oka, Kaluga, Zhizdra, Dnieper, Valdai) and nine interglacials
(Petropavlovka, Gremychie, Semiluki, Muchkap, Likhvin, Chekalin, Cherepet', Mikulino, and the Holocene), which are represented either as complete climatic rhythms of glacial and interglacial
rank, or as considerable portions of climatic-phytocoenotic phases--constituents of the rhythm (Bolikhovskaya 1995, 2004).
It has risen higher during each of the recorded interglacials
and as we are now more than half way through a current interglacial
we should be worrying about coping with rising sea - not hiding from cosmic bombardment (and freezing because we dare not burn fuel)
Kirschvink's Neoproterozoic Snowball Earth model of severe, ten million-year-long global refrigerations when temperatures plummeted to -50[degrees]C, the world's oceans froze and all planetary biological activity was arrested only to be revived during short, brutal interglacials
Broecker also points out that loess, which was generated in copious amounts during the peaks of the glacial periods, wasn't produced during interglacials
