John Shanahan, civil engineer, President of Environmentalists for Nuclear - USA: In order to promote use of nuclear energy, it is necessary to understand how it fits in with other forms of energy, mainly fossil fuels. It is very likely that fossil fuels will be used until they are no longer economical to mine and extract from the earth. Fossil fuels produce H2O and CO2 as their main by-products. A debate rages whether CO2 from fossil fuels is causing irreversible, catastrophic global warming and many other severe weather phenomena. This website presents over 200 articles on all sides of this debate. Go to HOME and the main tab, ENVIRONMENT. This debate is important for nuclear power because we shouldn't use unsound scientific arguments about CO2 from fossil fuels. This article presents photos from around the world to help you decide on the current condition of Earth's climate and how it compares with the past. Is it good or bad? Is it getting seriously worse or not?
