Enhanced greenhouse effect

These processes tend to produce Hquids that are higher priced than those derived from cmde oil. Timing for commercialization depends on a number of factors, including price of cmde oil, need for energy self-sufficiency, and environmental considerations. The factors are different for each of the potential sources. Environmental considerations include polution from burning the fuel itself, poUution from the whole production cycle, and production of gases that are involved in the enhanced greenhouse effect (see Air pollution). 

Global warming is one of the most serious present-day issues for the human to overcome. The enhanced greenhouse effect was mainly caused by the rapid increase of carbon dioxide in the atmosphere since the Industrial Revolution. To resolve the problems about carbon dioxide emissions, several new methods to recover and utilize carbon dioxide have recently been developed. ... 

These emissions are giving rise to problems on a global scale, such as the enhanced greenhouse effect and depletion of ozone from the stratosphere. In addition, regional problems such as localized ozone creation and smog formation have also been... 

It had been assumed that the proportion of carbon dioxide remains constant and so it was put at the centre of the carbon cycle. However, there is increasing international concern about the increasing level of carbon dioxide in the atmosphere, which is believed by many scientists to contributing to the enhanced greenhouse effect and hence climate change (see Chapter 24 on the accompanying website).
