Antarctic climate results from a complex mix of
oceanic and atmospheric
circulation patterns, so there could also be other components
affecting the amount of snow accumulation in the region, Bromwich said.
For example: could different
oceanic circulation rates change the
oceanic CO2 sink / source behaviour, or could different atmospheric conditions change the mixing rates of atmospheric gases hence modify their
affect on the solar forcing?
And we know for sure that a lot more is going to
affect temperature and thus the blossoms than just CO2 — atmospheric and
oceanic circulation patterns will clearly have a big effect from year to year.
Changes in
oceanic circulation in the North Atlantic have influence on a planetary level by
affecting, in particular, the water cycle.
The Antarctic ice sheet reached the coastline for the first time at ca. 33.6 Ma and became a driver of Antarctic
circulation, which in turn
affected global climate, causing increased latitudinal thermal gradients and a «spinning up» of the oceans that resulted in: (1) increased thermohaline
circulation and erosional pulses of Northern Component Water and Antarctic Bottom Water; (2) increased deep - basin ventilation, which caused a decrease in
oceanic residence time, a decrease in deep - ocean acidity, and a deepening of the calcite compensation depth (CCD); and (3) increased diatom diversity due to intensified upwelling.
As a consequence, it is likely that ice cover and
oceanic circulation will be
affected, and the wave climate will change.
If we can model paleoclimate as a function of landmass distribution and
oceanic circulation, we have a huge leg up because they are obviously major factors
affecting climate.
