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.
