By analyzing the relationship between the sunspot number index and cosmic rays on low cloud cover and temperature over Iraq, which is located within latitude 33°N and longitude 43°E, the aim of this study to know solar activity affects climate change. The sunspot data for this study is obtained from the World Data Center for the International Sunspot Number (ISN), cosmic ray data from the Neutron Monitor Database and atmospheric parameters data from the Climate Data Store for the period from 1996 to 2021, representing solar cycles 23, 24, and 25. Time series and regression analysis are used. The results showed a strong inverse relationship between sunspot cycles and cosmic rays, the relationship is weak for low cloud cover with sunspots and cosmic rays. As both cosmic rays and temperatures increased, cosmic rays, which serve as nuclei for cloud condensation, did not effectively contribute to
climatic cooling.
