Green house gases proceeding - Essay ExampleIn particular, the aim of carbon dioxide has make upd from 280 ppm to 360 ppm. Careful observations have made it clear that the increase of greenhouse gases concentration has contributed to increase in global warming (Global warming. In The cyclopaedia of Ecology and Environmental Management, Blackwell Science).Thus a close relationship between the greenhouse gases and global warming has been established. Scientists use mathematical models of the energy balance of the human beingss surface in relation to the properties of the atmosphere, to de conditionine the intensity of the relationship between greenhouse gases and global warming. These models are very helpful in establishing that increase in greenhouse gases concentration leads to increase in global temperature. A number of supercomputers have been employed to analyze the data and predict the possible effect of this relationship. In addition, weather scientists developed global cir culation models or GCMs for this purpose. If the current level of CO2 doubles, then there will be a long term change in surface air temperatures. It is predicted that such long-term change would result in a temperature increase of 1.5 to 4.5 degrees Celsius. Thus the average increase is predicted to be 2.5 degrees Celsius. As such, vegetation in the Northern hemisphere is experiencing the effects of global warming (Global warming. In The Encyclopedia of Ecology and Environmental Management, Blackwell Science).Greenhouse gases are molecules in the earths atmosphere that have more than two atoms. They have the capacity to retain heat reflected from the earths surface, which results in increasing the temperature of the earth. The whizz greenhouse gases are carbon dioxide or CO2, methane or CH4, ozone or O3, water vapor or H2O and minute quantities of CFCs or chlorofluorocarbons (Nave).It is vitally important to properly assess the harm caused
