Air Pollution & Climate Change: Global Phenomena, Individual Consequences

Breezometer

In the presence of heat and sunlight, chemical emissions from cars and factories react to form ozone (learn more here )., a harmful pollutant. As average temperatures rise, ozone levels accelerate. Repeated and excessive traffic pollution and poor air quality were determined to be linked to Ella's worsening asthma.

The State of the Air in 2024? Not Great

Union of Concerned Scientists

Since its inception, the report has effectively heightened the awareness of some hazardous air pollutants, and engaged the public, media, advocates, and policymakers in the ongoing fight against air pollution. The air quality for this report was calculated using data reviewed by EPA from 2020, 2021, and 2022.

State Air Regulations Can Go Above and Beyond National Standards 

Legal Planet

States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards ( NAAQS ) set by the U.S.

Improving EPA’s Latest Ozone Transport Rule

Acoel

The downwind air quality benefits are minimal. The proposed rule would provide de minimus air quality benefits in downwind areas with extremely high costs – estimated by EPA at $22 billion discounted 2016 dollars for the 2023-2042 period. enjoyed ozone reductions of 3 to 5 ppb or more. ppb by 2025.

Operationalizing Climate Science

Real Climate

Where, at the beginning, there was really only one input parameter (the CO 2 concentration) that needed to be coordinated, the inputs have now broadened to include myriad forcings related to other greenhouse gases, air pollution, land surface change, ozone, the sun, volcanoes, irrigation, meltwater etc. 27791-27792, 2020.
