    GREENHOUSE GASES


    CO2 - Carbon Dioxide

    Carbon Dioxide (CO2) is released when fossil fuels (coal, oil and gas) are burned. The increase in CO2 in the atmosphere is causing global warming.


    CH4 - Methane

    Methane (CH4) is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic wastes in municipal solid waste landfills, and the raising of livestock.


    N20 - Nitrous Oxide

    Nitrous Oxide (N20) is primarily emitted to the atmosphere from biological activity in soil and water, both natural and anthropogenic. Nitrous Oxide absorbs 270 times more heat per molecule than carbon dioxide.

    SMOG CAUSING GASES


    NOx - Nitrogen Oxides

    Nitrogen Oxides (NOx) form when fossil fuels and biomass are burned at high temperatures. They contribute to ground-level ozone (or smog), and to the formation of acid rain.


    SO2 - Sulfur Dioxide

    Sulfur Dioxide (SO2) is formed when fuels containing sulfur, primarily coal and oil, are burned. SO2 combines with water and oxygen in the atmosphere to form acid rain.


    03 - Ozone

    Ground-level ozone (the primary constituent of smog) is the most complex, difficult to control, and pervasive of the six principal air pollutants. Unlike other pollutants, ozone is not emitted directly into the air by specific sources. Ozone is created by sunlight acting on NOx and VOC in the air.(Source:EPA)

  • "Its also interesting to note that one gallon of gas burned, makes about 12 pounds of CO2 so you could 'buy' a ton by preventing about 180 gallons of gas from being burned - eg substituting out bicycling for 3500 miles of cars being driven (avg 20mpg), or not flying one person coast to coast (about the amount of fuel burned per person per cross atlantic flight)"

    SCIENCE

    PUBLIC SMOG has a Lower Park and an Upper Park, each for a discrete environmental challenges to the health of the atmosphere: Smog in the troposphere, and increasing greenhouse gas concentrations in the stratosphere.

    Smog generally occurs in the lower part of the atmosphere, less than 5 km above the ground. Smog is a combination of airborne particulate matter, like soot, and invisible toxic gases including ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), and carcinogens.

    Some of these compounds are emitted directly. Others are formed in the air from emitted pollutants, such as ozone from nitrogen oxide (NOx) photochemistry. Due to the importance of these secondary effects, smog mitigation often involves reduction of NOx emissions.

    Greenhouse gases - eg carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) trap outgoing radiation from the earth, allowing the earth to be warm enough to sustain life.

    However, due to human activity, notably the burning of fossil fuels, the concentrations of greenhouse gases in the atmosphere are increasing at an exponential rate, meaning that the rate at which CO2 is added to the atmosphere grows larger each year. This causes the average temperature to rise, which leads to potentially catastrophic impacts on the earth’s climatic balance.

    “Predictions of the next century show global temperature increases of up to 6oC (ten times the temperature change we have already seen) with land areas warming more than the average. We are looking at a future where impacts like coastal flooding, reduced crop yields, elevated rates of climate-related illness, and disrupted energy supply are virtually certain.” (Source: David Suzuki)
