This research aims to provide insight into the impact of solar activity on climate change by examining the relationship between the sunspot number index and cosmic rays with low cloud cover and temperature over Iraq, located at latitude 33°N and longitude 43°E. Sunspot data for this study are obtained from the World Data Center for the international sunspot number, cosmic ray data from the Neutron Monitor Database, and atmospheric parameter data from the Climate Data Store for the period 1996–2021, representing solar cycles 23, 24, and 25. Time series and regression analyses are employed. The results showed a strong inverse relationship between sunspot cycles and cosmic rays, while the relationship between low cloud cover and both sunspots and cosmic rays is weak. As both cosmic rays and temperatures increased, cosmic rays did not play an effective role in cooling the climate by acting as cloud condensation nuclei.
