What is global warming?
How Global Warming Works
The Suns energy passes through the cars 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.Example of the Greenhouse Effect
Whats the difference between global warming and climate change?
DifferenceGLOBAL WARMING is the increase of the Earths 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.

We can stop global warming!
What can you do to help solve the problem?
Simple Things To Do Turn off your computer or the TV when youre 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.

Simple Things To Do Dress lightly when its hot instead of turning up the air conditioning. Or use a fan. Dress warmly when its cold instead of turning up the heat. Offer to help your parents keep the air filters on your AC and furnace clean. Walk short distances instead of asking for a ride in the car. Plant a tree. Recycle.

********************** * Scientists agree that the burning of fossil fuels is causing global warming. Since these fuels are burned for energy, and everyone uses energy, everyone can help stop global warming just by using less energy or energy from renewable sources!
