What is global warming?
Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.
Some other examples of using energy and polluting the air are:
 | Turning on a light |
| Watching T.V. |
| Listening to a stereo |
| Washing or drying clothes |
| Using a hair dryer |
| Riding in a car |
| Heating a meal in the microwave |
| Using an air conditioner |
| Playing a video game |
| Using a dish washer |
