A gas found in the atmosphere. It is a byproduct of human respiration as well as a by product of an engine combustion from an automobile. CO2 is a heat-trapping gas in the atmosphere that reflects heat back down into the Earth.
The Greenhouse Effect
The ability of an earthly atmosphere to reduce heat loss from its surface, making it possible to use the absorption of solar radiation to warm the earth’s surface instead.
When substances are discharged into the air, such as from automobile or other engine combustions.
Compacted gasses, which discharge a high amount of CO2 into the atmosphere when sprayed, contribute to global warming.
The rapid increase of the Earth's overall temperature due to the release of too much Co2, methane, and other heat trapping gases.
Any fuel that is created from biomass (recently living organisms or their metabolic by-products, such as manure from cows) Unlike other natural resources such as petroleum, coal, and nuclear fuels, biofuels are a renewable energy source. They are 'carbon neutral' which means that although they release carbon into the atmosphere, they have already absorbed that carbon as plants. For this reason, Biofuels are championed by environmentalists as a way to reduce CO2 emissions.
