Observational evidences suggest that there is an apparent relationship between solar variability and the lower atmosphere. The assumption made in climate models that the variation in solar radiation can explain observed variations in the lower atmosphere is not entirely true. Past studies suggest that cosmic rays of both galactic and solar origin might be responsible for temperature change in the lower atmosphere. It is a fact that solar cycle is strongly correlated with the cosmic ray flux therefore it is desirable to search the physical mechanisms which mediate between solar activity and the global temperature. It is suggested that the observed variation in cloud cover might provide a possible link between varying solar activity and global temperature. Some other mechanisms might also be playing their roles in modulating the earth’s atmospheric processes. In this research article, we have attempted to explain how cosmic rays could modify the terrestrial temperature.
