Abstract: In order to study the stability of desert climate, the author analyzes the instability of Minqin desert climate in response to global warming with meteorological data of 1961- 2013 by using the slide standard deviation method and the linear trend line method. The results show that: (1) instability of monthly average temperature of January and April is increasing, isothermal date of February advanced 10.36 d from 1961 to 2013; (2) the instability of the extremely maximum temperature of December and January is increasing, and the instability of the extremely minimum temperature of July is increasing. The coefficient of variation of the extremely minimum temperature of May is up to 287.3%. In conclusion, the instability of desert climate of Minqin is increasing with global warming, and the stability of climate is worthy of public attention.
