Carbon dioxide increase causes air pollution deaths. Each degree Celsius rise in temperature caused by increased carbon dioxide levels could cause about 1,000 deaths from air pollution each year in the US, says Mark Jacobson of Stanford University, US. The gas boosts concentrations of surface ozone, particles and carcinogens, all of which are detrimental to human health.
Human activity--such as burning fossil fuels--causes more greenhouse gases to build up in the atmosphere. As the atmosphere thickens with more greenhouse gases, more heat is held in. Fossil fuels such as oil, coal and natural gas are high in carbon and, when burned, produce major amounts of carbon dioxide or CO2.
