Paradox lost. Shifting winds and corresponding ocean changes explain a seeming contradiction: the Antarctic Peninsula and Amundsen Sea growing warmer even as the
continent's interior keeps its cool.

Ozone is a greenhouse gas. Recent losses of ozone over Antarctica, may be cooling parts of the continent, thereby increasing High pressure.

Potential global warming in the rest of the world appears to be pushing the position of the circumpolar winds poleward

This has increased the pressure gradient, intensified winds and enhanced the circumpolar vortex.
