Scientists study Earth’s climate not just from observation but also from a theoretical perspective. Modern-day climate models successfully reproduce the key features of Earth’s climate, including the variations in wind patterns around the globe, the major ocean current systems such as the Gulf Stream, and the seasonal changes in temperature and rainfall associated with Earth’s annual revolution around the sun. The models also reproduce some of the more complex natural oscillations of the climate system. Just as the atmosphere displays random day-to-day variability that we term “weather,” the climate system produces its own random variations, on timescales of years. (more…)

air pollution problems created by coal combustion. Meanwhile, coal-fired power plants and industrial boilers spewed out tons of gaseous and particulate pollutants into the atmo- sphere. During combustion, the small amounts of sulfur and nitrogen in coal combine with oxygen to form sulfur dioxide (SO2), sulfur trioxide (SO3), and the oxides of nitrogen (NOx). (more…)

Prior to the Clean Air Act of 1990, environmental issues regulations were aimed at reducing emissions as they left the exhaust system. The catalytic converter has been the primary means of attacking air pollution in this way. After 1990, regulations for the first time undertook to alter the composition of the fuel itself. Reformulated gasoline applies to gasoline that is sold in the nine metropolitan areas designated by the EPA with the highest level of ozone in air pollution problems. About 48 million people reside in areas where ozone concentrations exceed federal standards. (more…)

The flux of carbon among terrestrial, aquatic, and atmospheric pools is at least partially controlled by photosynthetic processes. The relative carbon pool sizes have major effects on global climate system. The CO2 flux among land, sea, and atmosphere has, since the industrial revolution, been disturbed by a rapid injection of (more…)

Almost all fossil fuels use is by burning them to create energy. Burning process then produces waste products due to impurities in the fuel. There are few particulates as a resides and some gases such as sulfur dioxide, nitrogen oxides, and volatile organic compounds. These waste gases are then become air pollution orfossil fuels affecting our environment in destructive ways.
There are several types of air pollution: (more…)

In the beginning, human progress was limited by the amount of work in single day. This is only to feed themselves and their families. At that time, the economy was largely rural as a result. In the early of 19th century, more intelligent human began to looking for energy resources to support their lives. They began to develop coal, oil, and other stored energy to supplement their prime energy source: sunlight. Sunlight energy results in overgrown plant and animal growth over huge and dispersed areas and geologic time periods. There was, and will continue to be, abundant solar energy sources available to get more fossil fuel, to do research on how to exploit these resources more efficiently, and to use them in daily life and changing their cultures.
