3 How Global Warming Works Carbon Dioxide (CO2)Fossil fuels (coal, oil, natural gas)
4 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.
5 What’s the difference between “global warming” and “climate change”?
6 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 CHANGEis a broader term that refers to long-term changes in climate, including average temperature and precipitation.

23 We can stop global warming! 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!
25 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, orcurtains.Turn off the lights when you leave a room.Use compact fluorescent bulbs.

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