But for the other half of the picture — what happened in the oceans during that time — there is only a relatively short record extending back about 20,000 years to
the last glacial cycle.
The timing of this decline correlates with environmental changes associated with the onset of
the last glacial cycle, the team reports, whereas archaeological evidence does not support the presence of large populations of humans in eastern Beringia until more than 15,000 years later.
Building on this study, the team intend to produce a new reconstruction of global ice volume across
the last glacial cycle, which will help to validate their proposition that certain boundaries can define windows of instability within the climate system.
The timing of this decline correlates with environmental changes associated with the onset of
the last glacial cycle, whereas archaeological evidence does not support the presence of large populations of humans in Eastern Beringia until more than 15,000 years later.

Changes in the mode of Southern Ocean circulation over
the last glacial cycle revealed by foraminiferal stale isotopic variability.
The Vostok ice cores produced data demonstrating a close link between carbon dioxide and temperature through
the last glacial cycle.
The PalMod project is funded by the Federal Ministry of Education and Science (BMBF) to understand climate system dynamics and variability during
the last glacial cycle.
Such THC reorganizations play an important part in rapid climate changes recorded in Greenland during
the last glacial cycle (42, 43).
There is plenty of evidence of past climate change which was abrupt on timescales of 10 - 100 years through
the last glacial cycle and beyond.
Southern Ocean bioproductivity during
the last glacial cycle — new detection method and decadal - scale insight from the Scotia Sea.
If 1 and 2 are true, it's a simple matter to compute the ESS to GHG based on
the last glacial cycle because you're going from one equilibrium combination of ice, dust, vegetation, and GHG to another, and it doesn't matter what processes got you there.
