Antarctic Polar Desert

The largest and coldest desert on Earth, covering an entire continent/Deserts

Antarctica is technically the world's largest desert by area, receiving less than 200 mm of precipitation annually (mostly as snow), with some interior regions receiving less than 50 mm. The ice-free McMurdo Dry Valleys haven't seen rain in roughly 2 million years. The Antarctic ice sheet averages 2,160 m thick and contains about 26.5 million cubic kilometers of ice, representing roughly 70% of the world's fresh water. Temperatures have reached -89.2 degrees C at Vostok Station, the coldest reliably recorded temperature on Earth.
