Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).

I think it as arrogant to declare, based on our understanding of positive and negative feedbacks — both physical and biological — that our influence in these feedbacks are negligible and insignificant, as it is to declare that we understand exactly how we influence those same processes.

AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on land and oceans as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing water mass from equatorial latitudes and transporting this water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..

They openly acknowledge the importance of the GHG - GHE in establishing the disequilibrium conditions that lead to a lapse rate and atmospheric heat transport in the first place, but then analyze that motion to argue that the overall feedbacks of this process are negative, not positive, something that actually explains the remarkable stability of our atmosphere in the face of internal variability that (in a chaotic system) could easily drive it to catastrophe.

This saturation effect is due to negative feedback at high temperatures from chemical decomposition (molecules hitting so hard they break up) or a reversed reaction process where the breakdown of the reaction products at high temperature cancels out the enhancement in production rate by temperature, and it is similar to the negative feedback from H2O on the effect of CO2 injections, see for example Figure 6 in http://vixra.org/pdf/1302.0044v2.pdf.
