Based on climatic model simulations, global temperatures can be expected to rise by 1 to 5.5 degrees Celsius by 2100. Given the consequences of climate change, recognizing this phenomenon is important in order to have a specific strategy to reduce its effects. In order to study the trend of climate change using Kendall Mann method was evaluated and according to the selected criteria affecting green space and weighting by AHP method, green space adaptation index for Sabzevar city until 2040 was calculated. Changes in urban green space were assessed using satellite imagery and the NDVI index. The decrease in the area of ​​green space along with the expansion of the urban area in the period under study is clearly visible (during the statistical period under study, which corresponds to the historical period of climate models and observational data of Sabzevar). This study also shows that the increase in temperature in the next decade (2030-2021) will continue with greater intensity. In the next step, the per capita urban green space was calculated. According to the results of studying climate data, creating green space in proportion to climate change can play an effective role in adapting the city of Sabzevar to climate change. The use of climate-friendly green space and its changes will reduce greenhouse gases and provide a more suitable climate for humans and their activities. Due to the horizontal growth of the city and the rate of population growth, the amount of adaptation will decrease from 0.48 (in the basic period) to 0.32 in the period 2030-2021. A total of 15 indicators in four cultural, managerial, technological, ecological and plant criteria or each other in ArcGIS software were combined based on the coefficients of importance obtained by experts in the Expert Choice software
