Further, if
in the past we had roughly 90 GtC moving

in either direction would totally change things.

Volume,
in contrast, is crucial
in determining the vulnerability of Arctic sea ice to rapid future reductions (since thin ice is much more prone to react strongly to a single warm summer, making single very - low sea - ice summers more likely),
and the thickness of the ice determines the exchange of heat
between ocean and atmosphere.
For example, the optical thickness of the CO2

atmosphere winds up partially
in the
oceans, nor that the amount of CO2 going into or coming out of the

and does explain part of the variability about the long term rising trend.

On decadal
and longer time scales, global mean sea level change results from two major processes, mostly related to recent climate change, that alter the volume of water
in the global
ocean: i) thermal expansion (Section 5.5.3),
and ii) the exchange of water
between oceans and other reservoirs (glaciers
and ice caps, ice sheets, other land water reservoirs - including through anthropogenic change
in land hydrology,
and the
atmosphere; Section 5.5.5).
