Good question! The coldest (and driest) desert
in the world is the McMurdo Dry Valleys area of
Antarctica. One study of the climate of the Dry
Valleys from 1986–2000 showed that the average
annual temperature of different locations in the
Dry Valley ranged from approximately –15 to –30
Celsius (5 to –22 Fahrenheit; Doran et al.,
2002). That is well below freezing!
