What is global warming? Global Warming is the increase of
Earth's average surface temperature due to effect of greenhouse
gases, such as carbon dioxide emissions from burning fossil fuels
or from deforestation, which trap heat that would otherwise escape
from Earth. This is a type of greenhouse effect.
Slide 3
How Global Warming Works Fossil fuels (coal, oil, natural gas)
Carbon Dioxide (CO 2 )
Slide 4
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
Slide 5
Whats the difference between global warming and climate
change?
Slide 6
Difference GLOBAL 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.

Slide 25
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.

Slide 27
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.
