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.
