New NASA satellite images released this week demonstrate the reduction of air pollution across the US. After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide.

exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The engine was run on a unique and strenuous operating cycle that represented more closely the behavior of modern engines than operating cycles used in older long-term studies of TDE.

In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships.

After a thorough scientific review ordered in 2007 by the US Supreme Court, the US Environmental Protection Agency (EPA) issued a proposal with two distinct findings regarding greenhouse gases. Climate change has the potential to produce increases in ground-level ozone in many regions, according to the report.

After a thorough scientific review was ordered by the US Supreme Court in 2007, the Environmental Protection Agency (EPA) has issued a proposal on greenhouse gases. It has been deemed by the EPA that the emissions from new motor vehicles and their engines contribute to these concentrations and threaten climate change.
