How Global Warming Works

Example of the Greenhouse Effect

The Sun’s energy passes through the car’s windshield.

This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.

difference
GLOBAL WARMING

is the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.

CLIMATE CHANGE

is a broader term that refers to long-term changes in climate, including average temperature and precipitation.

Simple Things To Do

Turn off your computer or the TV

when you’re not using it.

Take shorter showers. Heating water uses energy.

Keep rooms cool by closing the blinds, shades, or

curtains.

Turn off the lights when you leave a room.

Use compact fluorescent bulbs.
