Computer-generated map of the world showing the distribution of carbon dioxide released from the combustion of fossil fuels. The map was created using country statistics of natural gas,crude oil & coal consumption for 1987. Estimates of carbon dioxide emissions were then distributed geograph- ically based on the human population (this assumes that energy is distributed on a per capita basis). The scale is measured in kilogrammes of carbon per square metre per year. Black areas indicate an absence of data. Levels of carbon dioxide,the most abundant & important of the greenhouse gases,are generally taken as an index of global warming | |
