Global dimming is a phenomenon which produces forces that act opposite to global warming in nature. Global dimming reduces the amount of sun’s rays reaching the earth’s atmosphere causing a drop of temperatures around the globe. In addition, global dimming interferes with the hydrological cycles in the biosphere and reduces evaporation rate. The study on global warming wouldn’t be complete without mentioning global dimming. Global dimming is caused by an increase in particulates such as sulfate aerosols in the atmosphere. The pollutants that lead to global dimming also lead to various environmental problems, such as phytochemical smog, respiratory problems, and acid rain. The present review discusses the combined effect of global dimming and global warming. Global Dimming and Global Alliance have been opposite phenomenon with contrasting effects and are destructive to plants. The effect can be reduced by every individual playing his role by reducing fuel consumption, creating awareness for the consumption of nonessential commodities, walking, and planting trees.
