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.

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.

Congress Considers First-Ever Purchase Incentive for Commercial EVs

Union of Concerned Scientists

Last week, Senators Schumer and Manchin announced a compromise on a reconciliation bill, called the Inflation Reduction Act of 2022 , that includes significant climate and air quality progress and a goal to reduce greenhouse gas emissions nationwide by 40 percent by 2030. A key step towards addressing climate change and air quality.

How climate change may impact ozone pollution and public health through the 21st century

Environmental News Bits

Climate researchers are learning that warming temperatures and heat waves resulting from greenhouse gas (GHG) emissions could adversely affect air quality in the United States and increase deaths from air pollution exposure. Read the full story from U.S. This effect is referred to as the “climate penalty.”

Clean Fleets Rule Slated to Deliver Healthier Air for Californians

Union of Concerned Scientists

Trucks and buses on California’s roads and highways are responsible for the majority of lung-damaging fine particulate and ozone-forming nitrogen oxide emissions, and a sizable amount of climate-warming greenhouse gas emissions as well.

The definitive CO2/CH4 comparison post

Real Climate

So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases. You might recall that GWP is defined as the ratio on per-kg basis of the temperature impact of other greenhouse gases compared to CO 2 over a specific time period.

Changes to California’s Electric Truck Proposal Could Reap Huge Climate and Air Quality Gains

Union of Concerned Scientists

The Advanced Clean Fleets (ACF) rule has the potential to significantly reduce climate-warming greenhouse gas (GHG) emissions as well as harmful air pollutants like fine particulates (PM2.5) A lower threshold would bring more reductions in air pollution sooner for the communities who need it most.
