Abstract:
In this research we studied the global warming by knowing the definition, and the causes. This research covers the Earth's atmosphere in details and the gases in each layer. Also the physical properties (pressure, thickness, temperature, speed of sound, density, mass), optical properties (scattering, absorption, emission, refractive index). Other aspects such as the Industrial Revolution and its role in the increase of greenhouse gases, the study covers United States of America, and China; as known there are the largest countries causing pollution due to heavy industry (ships, jets, cars, etc…. The study handled greenhouse gases and how it causes the global warming, the thing that made air pollution that cause climate changes. Finally, conclusion and recommendations were presented.
