Earth’s climate is a complex system of interacting natural components. These components include the atmosphere, the ocean, and the continental ice sheets. Living things on earth—or, the biosphere—also constitute an important component of the climate trends system.
Numerous factors influence Earth’s climate system, some of them natural. For example, the slow drift of continents that takes place over millions of years, a process known as plate tectonics, influences the composition of the atmosphere through its impact on volcanic activity and surface erosion.

The global dependence on fossil fuels developed during the Industrial Revolution, two centuries of economic and social development that transformed the way modern humans work and live. Most historians agree that the Industrial Revolution began in the early 1700s in Great Britain when machinery began to replace manual labor and animal power, and fossil fuels replaced wind, water, and wood as main energy sources.

The energy that people use every day comes from many different sources. The resources are divided into two main groups: renewable energy and nonrenewable energy. Renewable energy sources are those that can be used again and again. Renewable energy resources have unlimited supply. (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…)
