How wind helps Antarctic sea ice grow, even as the Arctic melts

Both the atmosphere & the oceans are heat engines. I.e. heat from the Sun provides energy to drive winds in the atmosphere & currents in the ocean. By these means, heat is redistributed around the globe. E.g., the climate of Western & Northern Europe is warmer than it would otherwise be, due to the North Atlantic drift, one of the branches of the Gulf Stream.

In the Antarctic, winds, intensified by global warming, are driving an expansion in sea ice:
