The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch Cycles.

As to the mechanics of both top down solar and bottom up oceanic influences on the surface air pressure distribution (and thus the movements of the climate zones) I have dealt with that in detail elsewhere so here suffice it to say that all climate change is simply the surface air pressure distribution shifting to accommodate those three primary solar and oceanic cycles.

In practice the power of the oceans is such that amplification could be more than 5 times up or down when all the oceanic oscillations are in line with solar changes which is just what we had from 1970 to 2000.

They suggest that the recent oceanic warming has caused the continents to warm through a different set of mechanisms than usually identified with the global impacts of SST changes.
