Candidate in the Department of Chemistry at Colorado State University Earths atmosphere is one of our greatest shared resources and provides many ingredients required for life. We breathe oxygen from the atmosphere, weather systems distribute water, and the ozone in the upper atmosphere protects us from harmful radiation.

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,

Unlike some of the other major air pollutants that affect our health, such as ground-level ozone (O3), nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ), and carbon monoxide (CO), particulate matter is the only example that isn’t a gas. In 2021, the WHO even tightened its annual and daily limits for PM 2.5

This, along with many other chemicals, like diesel particulates and ground-level ozone that form soot and smog, and metals like lead in paint and drinking water, are regulated by the EPA to keep us safe. PFAS is shorthand for a class of “forever chemicals” that persist in the environment indefinitely.

As for hurricanes, Texas suffered no fewer than 81 tropical or subtropical cyclones from 1980 through 2021. In 2015, when he took office as AG after stints in the Texas Legislature, he sued the Environmental Protection Agency for strengthening a standard for ground-level ozone, better known as smog.
