polar regions
Earth's icy caps
The polar regions are the areas surrounding Earth's North and South Poles, characterized by extreme cold, ice cover, and prolonged periods of darkness and daylight.
The Arctic in the north and Antarctica in the south represent Earth's coldest, most inhospitable environments: Climate change is affecting the polar regions faster than anywhere else on the planet.
