It is also possible for cold climates to increase chemical weathering in some ways, by lowering sea level to expose more land to erosion (though I'd guess this can also increase oxydation of C in sediments) and by supplying more sediments via glacial erosion for chemical weathering (of course, those sediments must make it to warmer conditions to make the process effective — downhill and downstream, or perhaps via pulsed ice ages -LRB-?)-RRB-.

George Kukla states, that increasing temperature will lead to increased snow precipitation and snow gains will offset the sea level rise — he warns of coming ice age; — RRB -.

There is the possibility that the relative importance of CO2 as a climate forcer increases as it transcends the other controllers of Earth's energy balance (some of which may be masked more in ice age studies — like uncertainties around the amount of ice age aerosol climate forcing, ice age thermohaline stability and as always insolation differences throughout the Pleistocene).

So when you transport enormous amounts of warm tropical waters to the poles for about 400,000 years, you end up with ice ages, which after a while may shut down the MOC again, further increasing the polar cooling, as for instance happened at the Younger Dryas.
