The Antarctic ice sheet is a massive layer of ice covering the continent of Antarctica. It is the largest single mass of ice on Earth, containing about 60% of the world's fresh water. The ice sheet is divided into two main parts: the East Antarctic Ice Sheet and the West Antarctic Ice Sheet. This ice sheet plays a crucial role in regulating global sea levels. As temperatures rise due to climate change, the ice sheet is melting at an accelerated rate, contributing to rising ocean levels and impacting coastal communities worldwide.
