One of the greatest challenges caused by air pollution is global warming, an increase in Earth’s temperature due to the buildup of certain atmospheric gases such as carbon dioxide. With the heavy use of fossil fuels in the 20th century, atmospheric concentrations of carbon dioxide have risen dramatically. Carbon dioxide and other gases, known as greenhouse gases, reduce the escape of heat from the planet without blocking radiation coming from the Sun. Because of this greenhouse effect, average global temperatures are expected to rise 1.4 to 5.8 Celsius degrees (2.5 to 10.4 Fahrenheit degrees) by the year 2100. Although this trend appears to be a small change, the increase would make the Earth warmer than it has been in the last 125,000 years, possibly changing climate patterns, affecting crop production, disrupting wildlife distributions, and raising the sea level.

Air pollution in Britain's cities could be as toxic to the heart as an oil slick, scientists have warned. Chemicals responsible for seriously damaging the hearts of fish caught up in the Exxon Valdez oil spill disaster could ... doing untold harm to humans

Taking into account which way the wind blows, it makes sense that North American pollution ends up in Europe at some point. But if the air stays close to the surface, Cooper explained, it moves very slowly, and the pollution tends to dissipate before reaching the Old World's shores.

Government regulations have reduced automotive air pollution by forcing the adoption of lead-free gasoline and catalytic converters. Newer engines that burn fuel more efficiently can reduce the volume of emissions while they economize on gasoline.

Once a "pollution event" formed, they had computer simulations that predicted where and when the air mass would show up in the skies over Europe. A research aircraft then made measurements of pollution levels in targeted areas.
