2. WHAT IS GLOBAL WARMING?
• It’s a long-term rise in the average temperature of the earth's climate system.
• It's an expression which refers to human activities that produce unnatural changes
in climate.
• Or, it’s an increase in earth temperature due to burning fossil fuel (Coal, Oil and
Gas) and large scale deforestation which results in emission of greenhouse gasses in
the earth atmosphere.

IS THE SUN TO BLAME?
• According to NASA, since
1978 a series of satellites
have measured the sun's
output energy and the data
show in more than 40 years
there is a slight drop in
solar irradiance.
• 2016 and 2020 are tied for
the warmest year on
records.

5. CAUSES
• Deforestation: burning forest
naturally or unnaturally and
destroying the jungles.
• Burning fossil fuel: usage of coal,
oil and gas in daily activity is one
of the main causes.
• Industrial and factories activities
are also another reason for
emission of carbon dioxide to air.
• Garbage: The waste sector is one
of three key methane emitting
sectors.

6. CONSEQUENCES
• End of human and other living
organism in earth.
• Melting down the thousands years
of ice age.
• Heavy hurricane and storm.
• Intense drought.
• Everything will be changed.

HOW TO PREVENT
• It’s a global issue and not related to single community.
• A proper norm should be followed by all countries directed
by UN.
• Recycle every possible thing to avoid garbage incineration.
• Stop deforestation and plant more trees.
• Use public transportation and stop idling in cold weather.
• Using of renewable energy specially Solar and wind
generated energy.
