A variety of hypotheses, involving sub-ice-shelf melting, stratospheric ozone depletion and tropical teleconnections, have been proposed to explain the observed Antarctic sea-ice expansion over the period of continuous satellite monitoring and corresponding model–observation discrepancy, but the issue remains unresolved. Here, by comparing multiple large ensembles of model simulations with available observations, we show that Antarctic sea ice has expanded due to ocean surface cooling… 


Tropical teleconnection impacts on Antarctic climate changes
Over the modern satellite era, substantial climatic changes have been observed in the Antarctic, including atmospheric and oceanic warming, ice sheet thinning and a general Antarctic-wide expansion
Tropically driven and externally forced patterns of Antarctic sea ice change: reconciling observed and modeled trends
Recent work suggests that natural variability has played a significant role in the increase of Antarctic sea ice extent during 1979–2013. The ice extent has responded strongly to atmospheric
Impacts of the north and tropical Atlantic Ocean on the Antarctic Peninsula and sea ice
It is suggested that the north and tropical Atlantic is important for projections of future climate change in Antarctica, and has the potential to affect the global thermohaline circulation and sea-level change.
Can natural variability explain observed Antarctic sea ice trends? New modeling evidence from CMIP5
The recent observed positive trends in total Antarctic sea ice extent are at odds with the expectation of melting sea ice in a warming world. More problematic yet, climate models indicate that sea
The Southern Ocean Sea Surface Temperature Response to Ozone Depletion: A Multimodel Comparison
The effect of the Antarctic ozone hole extends downward from the stratosphere, with clear signatures in surface weather patterns including a positive trend in the southern annular mode (SAM).
Sea Ice Trends in Climate Models Only Accurate in Runs with Biased Global Warming
AbstractObservations indicate that the Arctic sea ice cover is rapidly retreating while the Antarctic sea ice cover is steadily expanding. State-of-the-art climate models, by contrast, typically
Using Multiple Large Ensembles to Elucidate the Discrepancy Between the 1979–2019 Modeled and Observed Antarctic Sea Ice Trends
In spite of the unabated emissions of greenhouse gases into the atmosphere, sea ice around Antarctica has increased over most of the satellite era. Such an increase is not captured by climate models,
Antarctic Sea Ice Area in CMIP6
Fully coupled climate models have long shown a wide range of Antarctic sea ice states and evolution over the satellite era. Here, we present a high‐level evaluation of Antarctic sea ice in 40 models
Observed Antarctic sea ice expansion reproduced in a climate model after correcting biases in sea ice drift velocity
The results suggest that the reason CESM has failed to capture the observed Antarctic sea ice expansion is due to simulation biases in the sea ice drift velocity, implying that an improved representation of sea ice motion is crucial for more accurate sea ice projections.
Tropical Pacific SST Drivers of Recent Antarctic Sea Ice Trends
AbstractA strengthening of the Amundsen Sea low from 1979 to 2013 has been shown to largely explain the observed increase in Antarctic sea ice concentration in the eastern Ross Sea and decrease in
