The primary function of the polar ice caps is to act as a crucial climate regulator for the Earth. They reflect sunlight, helping to maintain the planet’s temperature and regulate weather patterns. The ice caps also play an essential role in the global ocean circulation system, influencing climate far beyond the polar regions. Furthermore, they serve as habitats for unique polar species and store vast amounts of freshwater. Melting ice caps due to climate change can lead to rising sea levels, threatening coastal ecosystems and communities worldwide.
