2. 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.

3. Why is global warming
happening?
Pollution from coal, natural gas,
and oil
5. Rising Sea Level Increased Temperature
Habitat Damage and
Changes in Water Supply
6. 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.
8. How is global warming
measured?
Ice Core Data
CO2 Measurements Before 1958 - Antarctica
9. The yellow represents warming, melting glaciers, flooding and
rising of sea level. The red represents the spread of disease,
earlier springs and population changes, heavy snowfalls, and
flooding, droughts and fires.
10. More intense and longer droughts have been
observed over wider areas since the 1970s,
particularly in the tropics and subtropics

11. The frequency of heavy precipitation events
have increased over most land areas
- Rainfall in Mumbai (India), 2005:
1 million people lost their homes
12. “Penguin
population
decline. Penguin
population have
shrunk by 33%
during the past
25 years in
response to
declines in their
winter sea ice
habitat.”
15. 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.
16. What’s the Compact
Incandescent difference? Fluorescent
500 lbs. of
coal
•1,430 lbs. CO2 pollution avoided
•$30 saved
17. Dress lightly when it’s hot instead of turning up
the air conditioning Or use a fan.
Dress warmly when it is cold instead of turning
up the heat.
Offer to help your parents keep the air filters on
your AC and furnace clean.
Walk short distance instead of asking for a
ride in the car.
Plant a tree.
Recycle.
18. Global warming is affecting plants,
animals, humans and the earth. We need to
learn how to conserve our use of fossil
fuels to minimize carbon dioxide
production. This will slow down the effects
of global warming.
Editor's Notes
From 1900 to 2005, precipitation increased significantly in eastern parts of North and South America, northern Europe and northern and central Asia but declined in the Sahel, the Mediterranean, southern Africa and parts of southern Asia. Globally, the area affected by drought has likely increased since the 1970s. {1.1} SYR SPM p.1 More intense and longer droughts have been observed over wider areas since the 1970s, particularly in the tropics and subtropics. WG1 {3.8, 3.9} (SPM p.8) About 25% of Africa’s population (about 200 million people) currently experience high water stress. WG2 Chap 9 p.435
