I can't imagine humans wanting to enter
conditions of the glacial period - unless skiing becomes very popular.

Instead, the fossil record indicates they vanished during the Earth's
glacial - interglacial transition, which occurred about 12,000 years ago and led to much warmer
conditions and the start
of the current Holocene
period.
During the last part
of the Pleistocene there were actually five major
periods of glaciation with four
periods of warmer non
glacial conditions between them.
If C02 is the largest single contributing factor to the Greenhouse Effect (because supposedly water vapor is only involved as a feedback to primary chemistry involving C02 itself), and C02 lags temperature increases (as has been stated on this very blog), how has the Earth ever returned to colder
glacial conditions following
periods of warming?
Carbon starvation, which apparently sometimes occurs during
glacial periods due to the low levels
of CO2 that are reached, has the same effect on C3 plants * trees, shrubs, and such) as do warm, dry
conditions when the warm is excesaive.
each
period of warming during the descent to the next
glacial stage should be more intense than the previous ones, as climatic variability increases outside the warm
conditions of an interglacial climatic optimum.
