... fossil fuels, natural gas, coal, and oil to power industrial processes and motor vehicles. Among the harmful chemical compounds this burning puts into the atmosphere are carbon dioxide, carbon monoxide, nitrogen oxides, sulfur dioxide, and tiny solid particles including lead from gasoline additives called particulates. Between 1900 and 1970, motor vehicle use rapidly expanded, and emissions of nitrogen oxides, some ... heat that is radiated from the ground below, trapping heat in the earth's atmosphere. This process is known as the greenhouse effect. Carbon dioxide is the most significa...

... increase the earth's albido, thus cooling the global climate. The focus of international climate change negotiations has been the emission of greenhouse gasses, particularly carbon dioxide, into the atmosphere. Without these greenhouse gasses, such as ozone, carbon dioxide, water vapor and methane, our planet would be much colder than it is today. (Cunningham, 2000) During pre-industrial times, levels of greenhouse ... of so-called "natural- events. For example, prior to the proliferation of land-based green plants, carbon dioxide levels in the stratosphere were much higher. These high l...

... C, making it nearly unsuitable for us to survive. Since the Industrial Revolution, there has been a significant increase in the emission of greenhouse gases, the majority of which is carbon dioxide. Chlorofluorocarbon and sulfur hexafluoride, other greenhouse gases, were introduced into the atmosphere for the first time following the Industrial Revolution. With this increase of greenhouse gases, the balance of heat ... is shattered. Now greater amounts of heat are kept in the atmosphere causing the temperature near earth's surface to rise in a phenomenon known as global warming. The g...

... 's ozone layer is because of the release of chlorofluorocarbons into the atmosphere. Chlorofluorocarbons also known as CFCs, are industrially produced chemical compounds that contain the elements chlorine, fluorine, carbon, and sometimes hydrogen that will break down the protective ozone in the atmosphere. Since CFCs are heavier than air, the process of CFCs reaching the ozone will generally take ... a decrease in stratospheric temperature is a coincidence, with the general increase in the lower atmospheric temperatures. Some speculate this is because of the reduced ozone above Antarcti...

The study envisions an onsite nuclear power plant, solar panel arrays, and methods for extracting carbon, silicon, aluminum, and other useful materials from the lunar surface. Another solution is a sort of "generation ship," for generations living aboard an enclosed ship, they could either remain ... up being tidally locked, with one hemisphere constantly facing the other star and the other constantly engulfed in inky darkness.
