The beginning and end of a glacial period are clearly times of global climate change, but there are also periods of abrupt change in climate patterns within those periods.

For example, we see in ice core records from Antarctica and Greenland that the world cycled in and out of glacial periods over 120Kyr cycles.

I have also seen your comments on WUWT where I read about your ideas on the termination of the glacial periods from a low vegetation / high dust environment as a result of low CO2 levels at the glacial peaks, which seems very plausible to me.

In one study, scientists found that gray whales in the Pacific are capable of feeding at both seafloor and surface levels, which has allowed them to survive fluctuations in food supply during a series of glacial periods.

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

Except for MIS 14, the temperature anomalies (relative to the mean temperature of the last millennium) of the coldest levels of all glacial periods range from around -9 to -9.5 °C with CO2 concentrations generally in the range 180 — 190 p.p.m.v..

Croll was actually a janitor at Edinburgh University and was self - taught in celestial mechanics and very interested in Louis Agassiz theory of glacial periods.

At the start of a glacial period, as more and more ice accumulates in the polar regions, more and more incoming solar radiation is reflected from the growing ice fields, which leads to further cooling.

Even the warmings out of the glacial periods into the interglacials only occurred at an average rate of something like 0.1 C per century (with coolings generally being even slower).

The duration and severity of the glacial periods increased during this period, with a particularly sharp change occurring between 900,000 and 600,000 years ago.

Amplitude and Duration: The most significant events are terminations of the glacial period and rapid onset of global warming of the interglacial period.

At the end of the glacial periods, CO2 increases about 80 ppm over ~ 10,000 years.

I've understood that he also predicted the ~ 1000 year time lag between temperature rise and CO2 at the end of a glacial period, before it was observed in the ice cores thanks to better dating techniques.
