How does climate change impact air quality?

• A. It can improve air quality by reducing pollutants
• B. It can exacerbate air pollution problems by increasing temperatures
• C. It has no effect on air quality
• D. It only impacts air quality in urban areas

Answer: (B)

Climate change significantly impacts air quality primarily through the mechanism of increasing temperatures. As the climate warms, it can lead to higher concentrations of pollutants such as ground-level ozone. This occurs because warmer temperatures enhance the chemical reactions that produce ozone, particularly when combined with emissions from vehicles and industrial sources. Additionally, climate change can influence meteorological conditions, which affects the dispersion and accumulation of air pollutants. For instance, stagnant air patterns can develop with shifts in weather systems, allowing pollutants to remain concentrated in certain areas, leading to health issues and environmental degradation. The increased frequency of extreme weather events, such as heat waves and wildfires, further contributes to the degradation of air quality by adding more particulate matter and other harmful pollutants to the atmosphere. The interaction of climate change with these factors illustrates how it exacerbates existing air pollution challenges rather than improving or negating them. Understanding the relationship between climate change and air quality highlights the need for comprehensive policies to address both air pollution and climate change simultaneously.
