In recent years, against the background of global warming, in some regions of Russia marked an intense change in climatic characteristics. This is manifested in the anomalous increase of winter temperatures and changes in rainfall. The article analyzes the change of climate parameters in arid zone according to the weather stations and mediopunto Astrakhan region for 1946-2015. and weather stations for Astrakhan 1922-2015 he Identified the increase in air temperature. The average rate of growth is on average 0.2В°C / 10 years in the region. The most significant increase in average temperatures observed in the cold season (an average of 1.2 В°C every 30 years). Changes in precipitation in the region is cyclical in nature with a slight decrease the last 15 years. The most noticeable seasonal changes in precipitation. The increase in precipitation is observed in spring and autumn (April, October, November), summer values of precipitation fell in July to 6 mm, in August at 8-9 mm., with increased air temperatures, reduced precipitation shows a trend of aridization of climate in the region.
