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 can be several kilometers thick in some areas, and it plays a significant role in Earth's climate system. The Antarctic ice is constantly changing due to natural processes and climate change. Melting ice contributes to rising sea levels, which can impact coastal communities worldwide. Scientists study Antarctic ice to understand past climate conditions and predict future changes in the environment.
