  • A gallon of gasoline, we learned, adds a whopping 19.6 pounds of CO2 to the atmosphere, a big chunk of our daily allowance. A kilowatt-hour (kWh) of electricity in the U.S. produces 1.5 pounds of CO2. Every 100 cubic feet of natural gas emits 12 pounds of CO2.
  • The greenhouse effect is when the temperature rises because the sun's heat and light is trapped in the earth's atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows, but it can't get back out. This is what the greenhouse effect does to the earth. The heat and light can get through the atmosphere, but it can't get out. As a result, the temperature rises.
