The ice in Antarctica doesn't just cover the land. There's also a large area of sea ice on the ocean's surface. Every year, the sea ice at the South Pole goes through a cycle. In the summer, the huge sea ice melts(融化) to its smallest point. Over the colder winter months, the sea ice grows. Usually, the sea ice covers the greatest area around September 23, as winter ends at the South Pole. Scientists have been measuring the area of the sea ice in Antarctica since 1979. For most of this time, Antarctica seemed to be almost unaffected by the changing weather conditions experienced in other parts of the globe. That began to change around 2016. Now, for several years, the area of Antarctic sea ice has been shrinking. In 2023, the U.S. National Snow and Ice Data Center (NSIDC) reported that Antarctic sea ice covered its greatest area on September 10 almost two weeks earlier than normal. And the sea ice extent was at a new record low—not just by a little bit, but by a lot. The last time Antarctic sea ice set a record low extent at the end of winter was in 1986. And in 2023, there's about 1.03 million square kilometers less sea ice than in 1986. Scientists are still trying to understand what is driving the change in Antarctica. One likely direct cause of the change is the rising temperatures of the world's ocean. Ted Scambos, a research scientist at the University of Colorado, says Antarctic ice levels have always changed some, but the sharp loss in 2023 is “pointing toward warmer ocean conditions around the continent.” The new low record has concerned the scientists. The sea ice is an important factor in lowering the temperatures of the earth. When it is frozen, sea ice reflects sunlight back out into space. But when the sea ice melts, ... ...
