One good example of the nexus between global warming and local pollution is ground-level ozone. It has been estimated that globally oil processing is responsible for about 15 percent of all VOCs released into the atmosphere. To make matters worse, NOx contributes to the formation of ground-level ozone and secondary PM2.5,
