4. Difference
GLOBAL WARMING
is the increase of the
Earth’s 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.
5. Basic Question of Global Warming
1. What causes the earth’s climate to change?
6. 1. Green House Effects
Example : carbon dioxide (CO2), Methane, Ozone, Nitrous oxide,
Sulfur Hexafluoride, Hydrofluorocarbons and etc.
7. 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.
Example of the
Greenhouse Effect
8. What are the causes of global warming ?
Man-made causes Natural causes

Oil companies (fossil fuels)

cattle producing methane)
Logging Industry (deforestation)

33. • From 1971 to 2005 CO2 vehicle emissions
rose from 1.8 billion tons per year to 4.6
billion tons per year.
• The average global air temperature rose
between 0.5 and 0.74 degrees C during the
past century.
• An average 2 degrees C warming is predicted
by 2100.
• Sea level has risen between 10 to 25 cm in
the last 100 years.
34. The Earth is getting warmer.
What causes the warming is
hotly debated.
