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…)

The question has long been not whether or not to reduce air pollution, but by how much and by what means. Since the extent of the reduced discomfort and illness is not clear—and the measurement of peoples’ willingness-to-pay (WTP) for reduced discomfort and illness is uncertain—it is not easy to know how much the pollution should be reduced. But it has always been clear that reducing automotive air pollution had to be part of the overall strategy. (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…)
