What I didn't see was mention of the role greenhouse gasses play
on ocean behavior, an area of intense study since it was discovered that oceans have been taking up much of our excess CO2, may be near the saturation point, and may endanger shellfish and reefs due to more acidic seawater.
For example, due to the lack of ocean data, secondary data is often used to infer what the ocean is doing — thus, the AMO analysis relies not on ocean temperature measurements, but rather on air pressure measurements as a proxy
for ocean behavior — iffy at best.
Coupled with paleontological analyses of marine microfossils in deep - sea sediments, these stable - isotope and trace - element microanalyses provide quantitative measures of global climate and
ocean behavior over diverse time scales.
Differences in the physics of
ocean behavior in a model can lead to differing effects from sea ice loss.
