2013年11月19日 · But new research suggests that a different mechanism—unrelated to climate change—is responsible for the ice growth. The real answer, says University of Washington oceanographer Jinlun Zhang, can be...

4 天之前 · In contrast, in the Antarctic the sea ice coverage has been increasing although at a lesser rate than the decreases in the Arctic. Shown below are up-to-date satellite observations of the sea ice covers of both the Arctic and the Antarctic, along with comparisons with the historical satellite record of more than 4 decades.

The satellite record reveals that a gradual, decades-long overall increase in Antarctic sea ice extents reversed in 2014, with subsequent rates of decrease in 2014–2017 far exceeding the more widely publicized decay rates experienced in the Arctic.

2022年2月11日 · Recent research offers new insights on Antarctic sea ice, which, despite global warming, has increased in overall extent over the past 40 years. An aqua and white iceberg, approximately 30 to...

2020年2月18日 · Antarctic sea ice peaks in September (the end of Southern Hemisphere winter) and usually retreats to a minimum in February. These image pairs show the average concentration of Antarctic sea ice for the month of September (left) and the following February (right) from September 1990 to February 2021.

2016年5月31日 · While Arctic ice is melting at a record pace, a team of NASA-led researchers say they can explain why Antarctic sea ice has been edging in the opposite direction. That paradox has puzzled...

2023年3月14日 · Antarctic sea ice extent each February from 1979 through 2023. Based on satellite data, extent is the total area where the ice concentration is 15 percent or higher. In the past decade, the February summer minimum has been extremely variable, hitting both near-record highs and record lows.

2023年9月16日 · Antarctica's huge ice expanse regulates the planet's temperature, as the white surface reflects the Sun's energy back into the atmosphere and also cools the water beneath and near it. Without...

2023年2月11日 · Antarctic sea ice is gradually increasing for a number of reasons, including changes in winds, increased ocean stratification and increased freshwater flux from melting glaciers and ice caps.

Sea ice around Antarctica plays a crucial role in the global climate. It influences ocean circulation and temperature, ocean-atmosphere interactions, and provides a critical habitat for marine ecosystems.
