Climatic conditions are delicately adjusted to the composition of the Earth’s atmosphere. If there were a change in the atmosphere for example, in the relative proportions of atmosphere gases the climate would probably change also. A slight increase in water vapor, for instance, would increase the hem-retaining capacity of the atmosphere and would lead to a rise in global temperatures. In contrast, a large increase, in water vapor would increase the thickness and extent of the cloud layer, reducing the mount of solar energy reaching the Earth’ surface.
level of carbon dioxide, CO2, in the atmosphere has important effect on climatic change. Most of the Earth’ s incoming energy is short-wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the received energy as a long-wavelength radiation, which CO2
