Magmatism and glacial cycles: coupled oscillations?

Alternative title:
How variable volcanic (MOR) CO2 emissions provide a non-linear coupling with sea-level that leads to 100ka glacial cycles
Abstract:

The Earth's climate system is driven by varying insolation from the Sun. The dominant variations in insolation are at 23 and 40 thousand year periods, yet for the past million years the Earth’s climate has glacial cycles at approximately 100 kyr periodicity.

These cycles are a coupled variation in temperature, ice volume, and atmospheric CO2. Somehow the Earth system’s collective response to 23 and 40 kyr insolation forcing produces 100 kyr glacial–interglacial cycles.
