This term was first used by Nils Gustaf Ekholm in 1901. Ekholm was an early adopter of climate control. His early studies included how the burning of coal could add unnecessary levels of carbon dioxide to the atmosphere.

Chlorofluorocarbons, aka CFCs, are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the production of aerosol sprays, foams and packing materials, as solvents, and as refrigerants. Though mostly inert in the lower atmosphere, that low reactivity affords CFCs a lifespan that can exceed 100 years, giving them time to diffuse into the upper atmosphere and stratosphere. Once in the stratosphere, the sun's ultraviolet (or thermal) radiation is strong enough to cause the cleavage of the bond, making it an active ozone reducer. Furthermore, CFCs absorb and emit absorb and emit infrared radiation in the wavelength range emitted by Earth, make them potent greenhouse gases.

The greenhouse effect occurs as the temperature within the Earth's atmosphere rises. Greenhouse gases trap the heat within the Earth's atmosphere. As sunlight enters the Earth's atmosphere, it passes through the gaseous layer and the Earth's surface absorbs part of the energy and reflects some energy. These reflected rays of energy get trapped between the Earth's surface and the atmosphere. Some common greenhouse gasses include: carbon dioxide, methane, nitrous oxide, and tropospheric ozone. Helium and nitrogen are two gases in the atmosphere, but they do not contribute to the greenhouse effect.

The greenhouse effect can also be found on Mars, Venus, and Saturn's largest moon, Titan. The effect on Venus is large because of its dense atmosphere of made of carbon dioxide.

Chemical fertilizers are produced to fix nitrogen for farmers' fields, and while fields naturally lose nitrogen to the atmosphere in the form of , increased abundance of fixed nitrogen results in more being released. Feedlots produce large quantities of nitrogen-rich animal waste, which also decays and enters the atmosphere in massive quantities.
