Antarctica is warming, although changes in atmospheric circulation brought about by the Antarctic ozone hole have been a temporary mitigating factor that has reduced the overall amount of warming, primarily in summer
2016 Key Finding2016During the past half-century, western Antarctic surface temperatures have shown general warming trends, with significant regional patterns. Cooling of the lower stratosphere because of ozone depletion in spring and early summer has helped to mitigate the amount of warming during the...
