Aim #79: How have air pollutants affected
the atmosphere?
1) Carbon Dioxide in the
Atmosphere:
The amount of carbon dioxide in the atmosphere has
been rising.
2) How do we contribute to the increase
of carbon dioxide in the atmosphere?
1)Burning of fossil fuels
2)Deforestation
3)Cow flatulence
(methane)
+
CO2, SO2, NO2
3) How does Deforestation cause an
increase in atmospheric carbon dioxide?
+
H2 O
Glucose
CO2
O2
Increased CO2 in the atmosphere
4) What does increased levels of carbon
dioxide in the atmosphere cause?
Increased levels of CO2 in the atmosphere trap the
heat that would normally radiate back into space.
This increase in earth’s temperature is called:
Global Warming

5) What are some of the detrimental
effects of Global Warming?
Melting of the polar ice caps, leading to a rise in sea
level and flooding in many coastal areas.
6) Disruption of the Carbon/Oxygen
Cycle:
Deforestation &
Fossil Fuel Burning

Global Climate Change
7) What are chlorofluorocarbons?
•Found in aerosol cans
•Refrigerator Emissions
•Air Conditioner
Emissions
CFC’s
8) What is the problem with
using CFC’s?
•They create holes in the ozone layer around earth.
•This layer prevents UV radiation from reaching earth.
9) How can UV radiation affect
living things?
•Mutations
•Cancer
