Furthermore, airborne chemicals that originate inside a house don’t stay there: Volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do.

Previously, the fact that these compounds are water-soluble never presented any problems since the Atacama Desert is one of the driest regions in the world.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below.

These connections arise because in many cases the agents of concern are the same, and in many cases the sources of the agents are the same or intimately connected.For example, surface ozone is both an air pollutant and a greenhouse gas. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs.

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

Warming of the air by any chemical, including soot, enhances natural surface emissions of water vapor [e.g., 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b]. These three gases are all greenhouse gases, and ozone is a surface air pollutant. Dessler et al., Guenther et al.,
