Answer 1

Answer:

Carbon dioxide is a green house gas with wanning effect of 60%. Green house gases are essential for keeping the earth warm and hospitable. They prevent a substantial part of long wave radiations emitted by earth to escape into space and radiate a part of this energy back to the earth. The phenomenon is called green house flux. Because of green house flux, the mean annual temperature of earth is 15°C. Recently the concentration of green house gases has started rising that is resulting in increasing the mean global temperature. It is called global warming. Deforestation has reduced carbon dioxide assimilation. The excess remains in the air. Excessive use of fossil fuel is adding more CO2 to atmosphere. This causes green house effect.
