The primary impact of climate change on polar regions is the rapid loss of ice cover, which disrupts ecosystems and threatens biodiversity. Melting ice affects species that depend on stable ice habitats, like polar bears and seals, leading to potential extinction. Additionally, warmer temperatures impact ocean currents and weather patterns, exacerbating global climate changes. The albedo effect, where less ice means less sunlight reflection, accelerates warming. Addressing climate change effects in polar regions is crucial for global ecological health and requires immediate and substantial mitigation efforts.
