ABSTRACT
Climate change presents a unique threat to the global environment of the whole world. Scientific evidence now clearly indicates that the earth’s climate is rapidly changing mainly as a result of increases in greenhouse gases caused by human activities. Human activities are changing the composition of the atmosphere and its properties. Many human activities are affecting the climate through increasing emissions of heat trapping gases, greenhouse gases (carbon dioxide, methane, nitrogen, and sulfur oxides). Increased fossil energy use, agricultural activity and deforestation leads to an increase in the level of atmospheric greenhouse gases, which trap a portion of the radiation from earth. As it is known, the increasing of the earth’s surface temperature is leading to increased weather variability, a rise in sea level, the spread of diseases, and enhanced air pollution.
