Antarctic ice sheet gains 695 billion tonnes of ice

A scientific study published in the journal Nature reveals that the Antarctic ice sheet experienced an exceptional mass increase of approximately 695 billion tonnes between July 2021 and April 2023. This growth was driven by heavy snowfall in specific regions, particularly in East Antarctica, including Queen Mary Land and Wilkes Land.

Researchers attribute this phenomenon to atmospheric changes caused by a large, warm tropical oceanic zone in the western Pacific and eastern Indian Ocean. This warming altered atmospheric circulation, transporting moisture-laden air toward East Antarctica, where it fell as significant precipitation. This snowfall temporarily offset ice losses caused by glaciers flowing into the ocean.

While this short-term increase is notable, scientists emphasize that it does not reverse the long-term trend of ice loss on the continent. The findings highlight the complex mechanisms influencing polar regions as global temperatures continue to shift.
