Unlike the Arctic, the Southern Ocean has shown little warming. An analysis of observations and numerical simulations suggests that Southern Ocean warming patterns are shaped by meridional overturning more than surface heating.

Simulations for CMIP6 With the AWI Climate Model AWI‐CM‐1‐1 (2020, background): “…responds much more slowly to changes in atmospheric thermal forcing because of the spatial structure of the global meridional overturning circulation (MOC), with circumpolar upwelling of unperturbed water masses in the south and downwelling in the north (Armour et al., 2016; Rackow et al., 2018).”
Observations of Clouds, Aerosols, Precipitation, and Surface Radiation over the Southern Ocean: An Overview of CAPRICORN, MARCUS, MICRE, and SOCRATES (2020, background): “The sea surface temperatures (SSTs) north of the subantarctic oceanic front (Armour et al. 2016) were above normal with an ~+1.”
Beyond the bipolar seesaw: Toward a process understanding of interhemispheric coupling (2018, background): “The relative isolation of the Southern Ocean is also demonstrated by its low rate of warming in response to anthropogenic greenhouse gas emissions, caused by upwelling of old unmodi ﬁ ed waters and equatorward ﬂ ow of surface waters (Armour et al., 2016).”
Causes of climate change over the historical record (2019, background): “Exceptions are the off-equatorial and tropical regions of the central and eastern Pacific associated with the transition to a negative Interdecadal PacificOscillation phase (Zhang et al 1997, Power et al 1999) coincident with the early-2000s hiatus (Kosaka and Xie 2013, England et al 2014), and the ”
The Polar Amplification Model Intercomparison Project (PAMIP) contribution to CMIP6: investigating the causes and consequences of polar amplification (2018, unknown): “Polar amplification is projected to occur at both poles, but to be delayed in the Antarctic relative to the Arctic due to strong heat uptake in the Southern Ocean.”
The Dependence of Global Cloud and Lapse Rate Feedbacks on the Spatial Structure of Tropical Pacific Warming (2018, background): “…general circulation models (AOGCMs) suggest that surface temperature change is initially delayed in the southeast tropical Pacific and Southern Ocean in response to forcing (e.g., Senior and Mitchell 2000; Held et al. 2010; Li et al. 2013; Andrews et al. 2015; Armour et al. 2016; Luo et al. 2017).”
Causes of Higher Climate Sensitivity in CMIP6 Models (2020, background): “, 2016)? It is worth noting that cloud feedbacks are enhanced in CMIP6 primarily over the Southern Ocean, a region of efficient ocean heat uptake (Armour et al., 2016).”
