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.
Key Points There is a scientiï¬c consensus that concentrations of greenhouse gases in the atmosphere are increasing and that this is causing global climate change. Human-driven emissions of carbon dioxide and other greenhouse gases, as well as land-use change, are the processes primarily responsible for the increase.
