Rapid urban expansion and industrialization have caused greenhouse gas (GHG) emissions and increased global temperatures. The continuation of global warming will not only cause many cities to depopulate but also cause a wave of mass migration. Since cities produce about 70 to 80 percent of greenhouse gases, they play a critical role in the formation and expansion of climate change, so it is necessary to review urban development plans, especially in the physical aspect, and responsive city plans according to the location of each city. The purpose of this research is to investigate and categorize the physical indicators affecting temperature changes in cities of hot and dry climates. The research methodology is practical in terms of purpose, and descriptive in terms of method, with quantitative and qualitative analysis. In this research, using remote-sensing software and literature analysis, physical indicators affecting climate comfort and climate change have been categorized and prioritized in four scales: city/ neighborhood unit/block/building plot. To check the indicators with an emphasis on the urban block scale, five urban blocks with different physical characteristics were modeled and evaluated in Envi-met v5-4 software. The findings show that changes in the street pattern/orientation, Spatial arrangement of buildings, the pattern of distribution and vegetation density, and the height of buildings relate to creating climate comfort and reducing energy consumption. investigation of the physical indicators responsive to climate change and thermal comfort in other climates and spatial scales is suggested for future studies.
