Dissolves magnesium and calcium and releases aluminum in soil making it difficult for trees to grow

Impede growth and seed production, reduce functional leaf area and accelerated aging in plants

Binds to hemoglobin in the blood, reducing the ability of blood to carry oxygen

Excess exposure to humans causes rapid breathing, confusion, increased cardiac output, elevated blood pressure that can lead to suffocation

US: monitors the 6 Criteria Air Pollutants

Lower greenhouse gas emissions to combat climate change

Agreement to lower CFC emissions to combat ozone depletion

Solar heat is trapped near Earth's surface by gases in the atmosphere

A warm layer on top of the colder layer of air keeps tall clouds from forming, prevents precipitation and traps air pollutants near the surface of the earth

The fraction of sunlight that is reflected by a body or surface. Snow = high / asphalt = low.

Warmer temperatures due to an abundance of surfaces that absorb heat (aka: more pavement)

Emissions are higher in areas where there are a lot of cars

Higher in areas like construction sites, unpaved roads, smokestacks or fires

Emissions are higher in places where we manufacture or use of everyday products and materials

Emissions tend to be located near large point sources such as coal-fired power plants or large industrial facilities

Higher levels in the air may occur when fertilizer is applied to farm fields.

Cars. Ex: Los Angeles, USA

Coal. Ex: Beijing, China

Northeast USA due to higher #s of people, industry and power plants
