The global warming potential is a measure of how much a given mass of a chemical substance contributes to global warming over a given period. Global warming potential is the ratio of the warming caused by a substance to the warming caused by a similar mass of carbon dioxide. Therefore, the global warming potential of carbon dioxide is defined as 1.0, while water has a global warming potential of 0. Chlorofluorocarbon-12 has a global warming potential of 8500, while chlorofluorocarbon-11 has a global warming potential of 5000. Various hydro chlorofluorocarbons and hydro fluorocarbons have global warming potentials ranging from 93 to 12,100. These values are calculated over a 100-year period. The information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
