Arctic ice refers to the frozen water found in the Arctic Ocean and surrounding regions. It includes both sea ice, which forms from seawater, and glaciers, which are large masses of ice formed from compacted snow. This ice plays a crucial role in regulating the Earth's climate by reflecting sunlight and maintaining cooler temperatures. The extent of Arctic ice varies seasonally, with maximum coverage typically occurring in March and minimum coverage in September. Over the years, scientists have observed a significant decline in Arctic ice due to climate change, impacting wildlife, such as polar bears, and global weather patterns.
