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).
