2. What does Global Warming mean?
Over the past 140 years, scientists have noticed the following:
• Increased global temperature
• Patterned increases and decreases throughout the year
Year vs. Average Global Temperature
1860 1880 1900 1920 1940 1960 1980 2000
3. Studying Earth’s core samples, paleoclimatologists know:
• Earth’s temperature is increasing at a rapid rate.
• Global Warming and Cooling is a cycle.
• Humans are altering and accelerating that cycle.
Year vs. Average Global Temperature
• Notice that
there are
increases and
decreases
every year.
• The average
temperature
is rapidly
accelerating.
1860 1880 1900 1920 1940 1960 1980 2000
4. • Global Warming is
caused by the inability
of the Sun’s heat to
escape our atmosphere.
• That inability is caused
by the thickening of the
Ozone Layer in our
atmosphere.
5. • The thickening of
the Ozone Layer is
caused by an

abundance of
Greenhouse Gases
in our atmosphere.
• Those Greenhouse
Gases are released
when humans burn

fossil fuels – fuels
containing Carbon.

7. • Production of farm animals
• Waste from farm animals (like
cows) releases large amounts
of methane into the
atmosphere.
• Deforestation
• When trees are cut down they
release the carbon that is inside
them into the atmosphere and
no longer absorb the carbon
dioxide for photosynthesis
8. Changes in Weather Patterns
• As the temperature of the atmosphere increases, so will the
temperature of the ocean and this will cause disruption of
ocean currents.
• This temperature increase will cause the climate and weather
to change all over the Earth.
9. Melting of polar ice caps and glaciers
• As temperature increases it causes glaciers to melt, which
leads to sea levels rising.
• There will also be an abundance of freshwater from caps in
oceans
• This could also lead to loss of habitats for animals.
10. Spread of Disease
• As temperatures increase, disease causing bacteria,
viruses, and organisms will spread to new places.
11. • Unfortunately, the damage has been done.
• We need to take the following steps to insure minimal
disruption:
• Invest in clean energy – no more fossil fuels
• Fossil fuels include Coal, Oil, Natural Gas.
• Some alternatives are: Solar Power, Wind Power,
Geothermal Power, Hydroelectric Power, Biomass

12. • Uses the power of the Sun to create energy.
• Effective, yet currently expensive.

13. • Uses the power of the wind to create energy.
• Effective, yet currently expensive.

14. • Uses the power of the Earth’s Core to create energy.
• Effective, yet currently very expensive to set up and use
efficiently.

15. • Uses the power of water to create energy.
• Effective, yet currently expensive.
• Very disruptive to water ecosystems.

16. • Uses the power of breaking down landmass to
create energy.
• Not as effective, also very dangerous.
• Disrupts natural habitats in large amounts.

17. • Increasing global temperatures have
negatively affected our environment.
• It is because of humans that the
average global temperatures are rising.
• The only way to stop the increase is to:
• Change the way that we are living
- Use clean energy
- Cease the burning of fossil
fuels
