Nearly Half of US Breathes Unhealthy Levels of Pollution—Cars and Trucks Largely to Blame

Union of Concerned Scientists

It presents air pollution data at the county-level for two pollutants, deadly fine particulate matter (PM 2.5 ) and ground-level ozone. is emitted directly from the tailpipes of gasoline and diesel vehicles, while ozone and even more PM 2.5 and ozone pollution 1. Internal combustion vehicles are largely to blame, since PM 2.5

Volatile Chemical Products: Important Contributors to Harmful Particulate Matter

HumanNature

We breathe oxygen from the atmosphere, weather systems distribute water, and the ozone in the upper atmosphere protects us from harmful radiation. One of the most well-known ways we have impacted our atmosphere is through the emission of greenhouse gases, which have adversely affected our climate.

The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

CMIP6: Not-so-sudden stratospheric cooling

Real Climate

The dominant factors are changes in CO2 (a cooling), ozone depletion (a cooling), warming from big volcanoes, and oscillations related to the solar cycle. That means the greenhouse substances are basically just CO2 and ozone, and they absorb in quite different parts of the spectrum. The basic concept is easy to grasp though.

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.

Federal Grants: Duct Tape or Catalyst for Environmental and Climate Justice? 

Union of Concerned Scientists

For example, EPA rules limiting ozone pollution or carbon from power plants move the first lever, while the combined $1.25 Administered by the Office of Air and Radiation, this program is $4.6 billion funding from the Inflation Reduction Act (IRA) and Bipartisan Infrastructure Law are clear examples of the latter.

How is Ocean Warming Impacting the Shipping Industry?

Ocean Conservancy

Some in the industry see the warming as an opportunity, as passages through the Arctic open for longer periods, even going so far as to claim there will be lower overall greenhouse gas (GHG) emissions from the shorter voyages.
