The various factors which affect the climate of Vinus, Mars,and Titan, are discussed. The climate of Mars is influenced by larger orbital changes, which generate extreme variations in solar forcing. The presence of water ice reservoirs at various positions across the surface also affect its atmospheric composition. The excessive loss of the carbon dioxide atmosphere and greenhouse effect prompted evaporation of liquid water. Mars's atmosphere is also affected by impacting extraterrestrial bodies and the effect of stronger solar wind. Venus's strong greenhouse effect due to IR radiation absorption by atmospheric CO2, SO2, and water vapor cause climate change. The chemical equilibrium governed by the balance between calcium carbonate, silica, and calcium silicate at the surface of the planet through the Bullock and Grinspoon process acts as source of carbon dioxide. The variation in solar TSI raise the temperature of Titan and affect its climate.
