GLOBAL WARMING
Do you aware of danger?
What is global warming?
• is an increase in the earth's temperature
due to fossil fuels, industry, and
agricultural processes caused by human,
natural, and other gas emissions.
How Global Warming Works
Carbon Dioxide (CO2)
Fossil fuels (coal, oil, natural gas)
What’s the difference
between “global warming”
and “climate change”?
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.
What is the reasons of global
warming?
• Greenhouse effects
• smoke from factory chimneys and exhaust
from cars
• Natural changes
• nuclear power
• The production of electricity, petroleum
gasoline, automobiles, and processing of
food.
Greenhouse Effects
• Emitted the gases to
•
the athmosphere
Occurance of new
layer
Production of energy
• Fossil fuel use, driven by
economic and
population growth, is the
major cause
Natural Changes
Volcanoes release gases
Change in the Sun’s energy
Circulations of the ocean

• Earth’s climate
changes naturally and
often produces
climatic extremes and
disasters
• Heat waves
• River and ocean

What can we do?
•
•
•
•
Efficient energy uses
Insolute to homes
Recycling
Leaving the car at
home
What governments can do?
• Establishing climate
•
•
•
change programmes
Intergovernmental
conventions
Regulations for
sustainable
development
Renewable energy
plants
Preventitive steps are crucial for us

• Everything is under the control of us, we
have to be aware of that. Otherwise, it will
be too late.
