A significant and ever increasing proportion of the human population of planet Earth is becoming informed — and concerned — about changes to the Earth’s environment; the atmosphere is rightly the focus of particular interest nowadays. Such changes may be either natural, such as due to volcanoes (both El Chichon in 1982 and Mount Pinatubo in 1991 put vast quantities of dust and sulphur into the lower stratosphere), or anthropogenic. Enhancement of the so-called greenhouse effect is caused by increasing the concentrations of infrared active trace gases in the atmosphere. This may be due to increased evaporation from the oceans (water vapour, H2O), deforestation or the burning of fossil fuels (carbon dioxide, CO2), increases of the cattle population or the area of paddy fields (methane, CH4), increases of chlorofluorocarbons (CFCs), or changed agricultural practices involving fertilizers (nitrous oxide, N2O).
