On the other hand, if the ice shell is sufficiently thick, the less intense interior
heat can be transferred to warmer ice at the bottom of the shell, with additional
heat generated
by tidal flexing of the warmer ice which can slowly rise and flow as do glaciers do on Earth; this
slow but steady motion may also disrupt the extremely cold, brittle ice at the surface to produce the chaos regions.

Guemas et al. (Nature Climate Change 2013) shows that the
slower warming of the last ten years can not be explained
by a change in the radiative balance of our Earth, but rather
by a change in the
heat storage of the oceans, and that this can be at least partially reproduced
by climate models, if one accounts for the natural fluctuations associated with El Niño in the initialization of the models.

slows, then the mass transported
by the Gulf Stream decreases, and the associated

CO2 (and some other gases) in the atmosphere are however more opaque to LWIR; they absorb that a chunk of that outgoing radiation and re-radiate it in all directions — so that a fraction less than half is re-radiated downwards; which has the effect of

heat (
by radiation) out of the atmosphere.

(57h) There is large horizontal - scale overturning (LHSO) that is driven
by a combination of differential horizontal net radiant
heating and differential vertical net radiant
heating; this overturning may be
slowed by smaller lapse rates but it can still occur and actually reduce the lapse rate below adiabatic (moist or dry) lapse rates.
If the surface temperature is
slow to catch up to that imbalance then the energy imbalance remains large, and we can have sufficient net
heating to cause much faster changes in the ice sheets than from the comparatively smaller imbalances caused
by the changes in Earth's orbit associated with the glacial periods in the past.
Slowing such overturning
by reducing the horizontal differential
heating could tend to allow
heat to build up at lower levels until the lapse rate is more favorable to localized vertical overturning (LVO)(The two forms of overturning are not always completely distinct or separate; for example, the Hadley cell, Walker, and monsoon circulations, as well as extratropical storm track activity (developing from baroclinic instability (Rossby wave phenomena)-RRB- are driven and organized in part
by horizontal differential
heating, but in the ascending portions of these circulations, cumulus - type convection can occur).
For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying out due to

by GW (reducing or cutting short their uptake of CO2 & releasing CO2 in the process) 3) ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more
heat 6) the warming
slowing the thermohaline ocean conveyor & its up - churning of nutrients — reducing marine plant life & that carbon sink.
The first rate seems to be far
slower because there are no winds in the stratosphere so that equilibrium can only be reached
