Antarctic Desert (13,829,430 square kilometers): The Antarctic Desert is the biggest desert from around the world. The Antarctic desert is a polar type desert located in the southern hemisphere’s Antarctic region. 98 percent of the Antarctic continent is filled with snow, while 2 percent of the land on the continent is clear of any snow. The Antarctic region is considered as one of the coldest places on earth where temperatures have been recorded to fall below -89.2 degrees C. due to the harsh weather and terrain, there is no permanent population in Antarctica. The land is occupied by a few research camps by scientists who have been allowed to set up camps since the signing of the 1959 treaty. Only 12 countries signed that treaty and are thus the only ones allowed there.
Arctic Desert (13,700,000 square kilometers): The Arctic desert is the second largest desert on earth and is located directly opposite the Antarctic desert. The Arctic region consists of huge ice-covered bodies of water which are surrounded by soil, below or at the freezing point of water i.e. 0 degrees. The arctic desert has a recorded low temperature of -68 degrees C.[irp]

The Gobi Desert (1,300,000 square kilometers): The Gobi Desert is a cold winter desert located in the north and northwestern parts of China, and the southern part of Mongolia. The temperatures during the summer months reach up to 50 degrees C. and in the winter the temperature drops to about – 40 degrees C. the area for the Gobi Desert is calculated at 500,000 square miles.
