The cold climate is responsible for maintaining the continent's year-round ice fields: They never melt. Even though Antarctica receives more sunlight than the equator, the temperatures are lower because the ice sheet reflects the heat back into space. Thus, the coldest temperature ever recorded on Earth was in Antarctica in July, 1983: Soviet scientists shivered through temperatures that fell to minus 89.2 degrees Celsius.
寒冷的气候使南极冰厚得可以常年维持：它们永不融化。虽然南极洲的光照比赤道多，气温却比它低，因为冰层能将热能反射回天空。因此，地球上的最低温度记录就是在1983年7月的南极洲：前苏联科学家在降至摄氏零下89.2度的低温中瑟瑟发抖。
