This study was conducted to examine the relationship between specific climatic parameters, namely ambient temperature and air pollution, and behavioral abnormalities—including aggression and impulsive behaviors—among children diagnosed with Autism Spectrum Disorder (ASD). The research was carried out in Khorasan Razavi Province, Iran, and the statistical population comprised children with ASD aged 4 to 13 years who attended daily educational–rehabilitation centers dedicated to individuals with ASD. From this population, a total of 186 children were selected through convenience sampling. Data on behavioral variables were collected using three standardized instruments: the Shaheem Children’s Aggression Questionnaire (2006) to assess levels and dimensions of aggressive behavior; the Hirschfield Impulsivity Scale (1965) to measure impulsivity traits; and the Gilliam Autism Rating Scale (1994) for confirming ASD diagnosis and severity. Simultaneously, climatic and air quality information—covering daily ambient temperature and concentrations of key air pollutants—was obtained from reliable local meteorological and environmental monitoring stations. The results demonstrated statistically significant relationships between both temperature and air pollution levels with the severity of aggression and impulsive behaviors in children with ASD. Higher temperatures and increased air pollutant concentrations were associated with elevated behavioral abnormalities. These findings underscore the importance of incorporating environmental and climatic considerations into the clinical management, educational planning, and rehabilitation program design for children with autism. Furthermore, they highlight the need for interdisciplinary collaboration  to develop strategies aimed at mitigating the adverse behavioral impacts of climatic and environmental stressors on vulnerable pediatric populations.

Heating requirements are one of the most important human issues in the fields of agriculture, tourism and energy management in the present and future .Knowing the extent of these changes can be very effective in making decision makers. The purpose of this study is to examine the changes in the requirements of the heating degree day in conditions of climate change in southern Khorasan province. For this purpose, daily data from the minimum and maximum temperature of 11 stations of the South Khorasan province were received from the Meteorological Organization of Iran during the period of 1990-2015. The latest available scenarios of the fifth report of the Climate Change Interagency Panel (AR5 2014) include RCP scenarios from the Canadian Climate Change website and, using the SDSM macroeconomic statistics software, the data for the upcoming period (2016-2046) in the study area was thrown off. Using the Matlab software capability, the monthly and annual heating requirements of the stations were calculated in the current and future period. Finally, using the Kriging interpolation method, the zoning maps for cooling requirements for the current and future period are mapped in ArcGIS software. By examining the effect of geographic features (latitude and longitude and station height) on the heating needs in the area, it was determined that the role of heights is very effective in changing the heating needs. In the cold months of the year (Azar, Dey and Bahman), the highlands (Qain, Arsak, Fath Abad, Aryan Shahr, Darmian) require higher energy levels due to the need for higher temperatures. Increasing the temperature and warming of the air in the future, especially in the months of Farvardin and Mehr in most places, requires less use of exhaustible equipment in the future.
