The major mid-Holocene forcing relative to the present was due to orbital perturbations that led to large changes in the seasonal cycle of insolation.

These orbital variations, which can be calculated from astronomical laws (Berger, 1978), force climate variations by changing the seasonal and latitudinal distribution of solar radiation (Chapter 6).
Although the primary driver of glacial — interglacial cycles lies in the seasonal and latitudinal distribution of incoming solar energy driven by changes in the geometry of the Earth's orbit around the Sun («orbital forcing»), reconstructions and simulations together show that the full magnitude of glacial — interglacial temperature and ice volume changes can not be explained without accounting for changes in atmospheric CO2 content and the associated climate feedbacks.
The pattern would respond to externally forced diurnal and seasonal and orbital - scale cycles with some lag time from thermal and mechanical and compositional, etc, inertia, but with a constant pattern of heat accumulation and depletion over each cycle.
What I actually said — and have always said — is that if the net of * all * feedbacks in the climate system is negative, then a mere seasonal and spatial reorganisation of TSI under orbital forcing would not be capable of terminating glacials.
Comparing the influences on the Last Interglacial climate with those assumed in future climate projections is problematic owing to fundamental differences, especially orbital forcing, seasonal warming, and greenhouse gas concentrations.
The major mid-Holocene forcing relative to the present was due to orbital perturbations that led to large changes in the seasonal cycle of insolation.
I came to think of solar radiation as being the ultimate (and only) external forcing of the climate system, which, except for the orbital seasonal changes and the 11 - year sunspot cycle, has been essentially constant over the past several decades of precision solar irradiance monitoring.
