The two leading theories to explain the record-breaking warmth are a reduction in tiny particles in the atmosphere called aerosols due to shipping fuel regulations that reduced sulfur oxide (SOx) emissions, or decreasing cloud cover. This question was a focus at the 2024 annual American Geophysical Union (AGU) meeting in Washington, D.C.,

Switching from fossil fuels like gasoline to increasingly clean electricity sources is vital for hitting climate and air pollution goals. These regulations (both state and federal) that UCS has advocated for have saved drivers money and reduced emissions. pounds of carbon dioxide emissions per gallon.

The abstract: In the late 1960s, New Zealand and the United States collaborated to establish a southern hemispheric carbon dioxide (CO2) monitoring station on New Zealand’s coastal cliffs. The precise nature of CO2 as an air pollutant, however, was difficult to pin down.

One option, a tax on carbon dioxide emissions, gets the most attention but seems politically impossible. The closest we’ve ever come to a carbon tax is a limited fee on methane emissions under the new IRA law. If a carbon tax were politically feasible, there would be a lot to be said in its favor.

The Court then held that greenhouse gases are covered by the Clean Air Act as a type of air pollutant. This gave EPA the power to impose limits on carbon emissions by vehicles and industry. Lucas appeared at the time to be the start of a sweeping constitutional attack on environmental and land use regulations.

Responsible for 12 percent of all US global warming emissions from human activities, methane traps significantly more heat per molecule than carbon dioxide, making it 86 times more harmful for the first 20 years after it is released into the atmosphere. First, there’s air pollution. Its primary component is methane.

May 11, the Environmental Integrity Project and Clean Air Council filed a federal lawsuit against the Shell Petrochemical Plant for repeatedly violating permitted air pollution limits from a massive new plastics production plant in Beaver County, which opened last year. In a lawsuit filed in the U.S.
