Desert Biomes
Climate InformationArid Deserts: Temperature ranges from 10 to 30 degrees C throughout the year. However, there tend to be large daily fluctuations in temperature – very hot during the day and very cold at night.
Cold Deserts: In some areas of the world, there are temperate climates that receive very little rainfall, such as coastal and mountain areas. Antarctica is also considered a cold desert.
In all deserts, rainfall is less than 25 cm (approx. 10 in.) per year.
Plants in the Arid DesertThe dominant plants in the desert are succulents, which have stems and leaves covered with a waxy coating, which helps them store water.

Threats to the Biome
Global Warming
The polar ice caps that make up the cold deserts of Antarctica are slowly melting, changing ocean temperatures, salinity, and sea level.
Lack of Water
As cities along the west coast become more populated, they draw water away from their natural sources, including the desert Southwest.
Urbanization
In many places, the desert is being converted to housing developments and golf courses.
