Air Pollution Air Pollution Causing Global Warming This paper presents the causes and effects of air pollution. Other stratospheric research is concerned with the downward trends in global ozone that have recently been measured over populated regions in the mid altitudes. The author focuses on the various factors associated with global warming. From the Paper: "Air pollution is any visible or invisible substance found in the air that is not part of the normal composition of air. Some air pollution is natural and has always been a part of the earth's history. However, over the past one hundred years or so, pollution created by humans has become a major environmental problem. Natural air pollution has been around for millions of year. Dust and a variety of gases from forest fires, volcanoes, and decaying material in rivers, oceans, and other bodies of water continually enter the atmosphere.
