On T.R.A.C.K.S. 3 Glossary of Climate Change Carbon Dioxide (CO2): A colorless, odorless gas that naturally exists in the earth's atmosphere. The major source of manmade CO2 emissions is from the combustion of fossil fuels. Carbon dioxide is the pri- mary greenhouse gas and is known to contribute to global warming and climate change. Carbon Footprint: The measure of the impact human activities have on the environment in terms of the amount of greenhouse gases produced, measured in units of carbon dioxide. Climate Change:According to the EPA, climate change refers “to any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer).” Composting: A process whereby organic wastes—food, paper, and yard wastes—decompose naturally, resulting in a product rich in minerals and ideal for gardening and farming as a soil conditioner, mulch, resurfacing material, or landfill cover.
