Antarctica stores enough frozen water to raise global sea levels by 58 meters, and knowing how much ice it's losing is key to understanding the effects of climate change today and in the future. The threefold jump in ice loss from the continent as a whole is a combination of increased mel...
由倒数第二段中Ted Scambos说的话“Antarctica’s ice levels have always changed some, but the situation this year is pointing towards warmer ocean conditions around the area.”(南极洲的冰平面总是有一些变化,但今年的情况表明,该地区周围的海洋条件更加温暖)”可知,Ted Scambos认为气温上升导致了南极洲...
