Antarctic ice refers to the vast ice sheets covering the continent of Antarctica. These ice sheets hold about 60% of the world's fresh water and are crucial for regulating global sea levels. The ice is formed from layers of snow that have compacted over thousands of years, creating thick glaciers that flow slowly toward the ocean. The Antarctic ice is also home to unique ecosystems, including various species of penguins and seals. As climate change causes temperatures to rise, the ice is melting at an accelerated rate, leading to concerns about rising sea levels and its impact on global weather patterns.
