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.
6. Difference
GLOBAL WARMING CLIMATE CHANGE
is the increase of the is a broader term that
Earth’s average refers to long-term
surface temperature changes in climate,
due to a build-up of including average
greenhouse gases in temperature and
the atmosphere. precipitation.
7. Effects of Global Warming
Rising Sea Level Increased Temperature
Habitat Damage and
Changes in Water Supply

24. 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.

26. 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 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!
