This may suggest that the decreased upwelling IR from the troposphere is offsetting the warming caused by increasing ozone.
It's always worth remembering that the other end of the AMOC involves two main factors: (1) vorticity - mixing of heat from surface waters into the deep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Current.
Is the upwelling a symptom of a change caused by the GHE due human carbon emission and land use changes?
Estimates of lags of CO2 seem to range from 800 years to about 1500 years, which is suggestive of oceanic upwellings and downwellings as being a prime cause of CO2 changes in the atmosphere.
upwelling wind blows, moves water away, causes new water to rise up to replace it brings up tiny ocean organisms, minerals, and other nutrients from the deeper layers of the water.
Glaciers along the Amundsen Sea terminate in deep water, and are most susceptible to periodic upwelling of that warmer deep water, which causes basal melting.49, 50,51,52
ENSO is not «sloshing» — in first cause it is upwelling in the eastern Pacific with feedbacks in wind, current and cloud across the Pacific.

«The overall slow decrease of upwelling SW flux from the mid-1980's until the end of the 1990's and subsequent increase from 2000 onwards appear to caused, primarily, by changes in global cloud cover (although there is a small increase of cloud optical thickness after 2000) and is confirmed by the ERBS measurements.»
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.
