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.

• Why is this warming bad??
• Greenhouse Gases
• Impacts
• What we can Do

3. 3Global Warming
What is Global Warming?
 Global Warming is the theory
that we as humans are
increasing greenhouse gases
(the layers of gases that catches
the sun’s rays and heats the
earth) through industrialisation
causing more gases and
increasing the amount of
sunlight that gets caught and
heat the Earth.
• GENERAL VIEWPOINT:
 The general viewpoint is that
global warming and pollution
from CO2 emission are adding
to greenhouse gases so
significantly that the Earth is
warming up and will continue
to warm.

Why is this warming bad ?
 We believe that this increase in temperature will
eventually cause the melting of the ice caps. This
melting could increase the oceans height by up to
2 feet in only one century !! This would mean
many heavily populated costal cities would flood
causing millions maybe billions of dollars and
damage and the potential loss of life in these
cities.
 Due to this natural disaster have been increasing,
disease have been spreading more rapidly, and
animals have been found migrating towards the
poles due to the increasing in heat.
 Global warming doesn't create hurricanes, but it
does make them stronger and more dangerous.
Because the ocean is getting warmer, tropical
storms can pick up more energy and become
more powerful.

Greenhouse Gases
• Carbon dioxide
– combustion of solid waste, fossil
fuels (oil, natural gas, and coal),
and wood and wood products
• Methane :
– production and transport of coal,
natural gas, and oil. Methane
emissions also result from the
decomposition of organic wastes
in municipal solid waste landfills,
and the raising of livestock.
• Nitrous oxide
– agricultural and industrial
activities, as well as during
combustion of solid waste and
fossil fuels.
• F-gas:
hydrofluorocarbons
(HFCs),
perfluorocarbons (PFCs),
and sulfur hexafluoride
(SF6),
– industrial processes.

Impacts of Global Warming
 The number of category 4 and 5 hurricanes have almost
doubled in the last 30 years.
 The flow of ice from glaciers in Greenland has more than
doubled in the past decades.
 At least 279 specie of plants and animals are already
responding to global warming, moving closer to the poles.
 Sea level rise became faster over the last century.
 Precipitation (rain and snowfall) has increased across the
globe, on average.
Other effects could happen later this century, if
warming continues.
 Sea levels are expected to rise between 7 and 23 inches (18
and 59 centimeters) by the end of the century, and
continued melting at the poles could add between 4 and 8
inches (10 to 20 centimeters).
 Hurricanes and other storms are likely to become stronger.
