Arctic Ice Sheets

Arctic ice sheets are massive layers of floating and thickening ice covering parts of the Arctic region, primarily over the ocean and landmasses like Greenland. They consist of both sea ice, which forms from freezing seawater, and glaciers or ice caps on land. These ice sheets play a crucial role in regulating Earth's climate by reflecting sunlight and helping control global temperatures. They are sensitive to temperature changes, and as the planet warms, they are melting and shrinking, contributing to rising sea levels and impacting global weather patterns.
