Over the last half of the twentieth century, surface temperature over the South Pole was steady if not slightly cooling, suggesting the high Antarctic interior might be immune to warming. Research now shows a dramatic switch; in the past 30 years, the South Pole has been warming at over three times the global rate.

变暖到达南极
