I originally post the following in the Arctic folder, but it belongs here as much as there:
While I have no proof of any correlation between the two polar sea ice deviations from their respective norms; nevertheless, I cannot help but to suspect that the recent large El Nino is contributing to the Antarctic low sea ice extent, while the associate weak La Nina is contributing the Arctic low sea ice extent (& and both deviations could be strengthened by positive cloud feedbacks). Paleo-data and model forecasts provide weight to such a possible chaotic strange (Lorenz) attractor type of behavior.
Edit 1: See the linked article entitled: "Lorenz attractors, fluids, chaos and climate".https://moyhu.blogspot.com/2016/11/lorenz-attractors-fluids-chaos-and.html
Edit 2: The following four linked references all indicate that consideration of chaos theory's strange attractors in paleo-eras demonstrate that climate sensitivity is higher than traditional (AR5) climate modeling projections have assumed.

Edit 3: The last linked reference cite model findings indicating that changes in extratropical clouds associated with a reduction in high latitude albedo can impact poleward atmospheric heat transport via changes in the Hadley cell:

Abstract: "The response of atmospheric heat transport to anthropogenic warming is determined by the anomalous meridional energy gradient. Feedback analysis offers a characterization of that gradient and hence reveals how uncertainty in physical processes may translate into uncertainty in the circulation response. However, individual feedbacks do not act in isolation. Anomalies associated with one feedback may be compensated by another, as is the case for the positive water vapor and negative lapse rate feedbacks in the tropics. Here we perform a set of idealized experiments in an aquaplanet model to evaluate the coupling between the surface albedo feedback and other feedbacks, including the impact on atmospheric heat transport. In the tropics, the dynamical response manifests as changes in the intensity and structure of the overturning Hadley circulation. Only half of the range of Hadley cell weakening exhibited in these experiments is found to be attributable to imposed, systematic variations in the surface albedo feedback. Changes in extratropical clouds that accompany the albedo changes explain the remaining spread. The feedback-driven circulation changes are compensated by eddy energy flux changes, which reduce the overall spread among experiments. These findings have implications for the efficiency with which the climate system, including tropical circulation and the hydrological cycle, adjusts to high latitude feedbacks, over climate states that range from perennial or seasonal ice to ice-free conditions in the Arctic."
