Introduction
• Climate change is an enormous challenge facing
humankind today.
2
• Undoubtedly,it is the single largest environmental
threat facing the planet,and we need to act fast to
mitigate it.
3
• There is much that need to be done and much that
can be done to halt the catastrophic impacts of
cliamte change.

•
The Climate of
a given place is
the average
weather
experienced in
that place over
a perios of
time.
What is Climate.
Climate is the
average
weather of a
region or area
over a period
of time.(35
years).
Various
elements of
climate such as
rainfall,
• temperature
• humidity
• Air pressure
• winds
• clouds and
• sunshine

What is Climate Change.
Climate Change is natural phenomenon and has been
occurring since the earth came into being.
Climate change is a change in the average weather of
a given area or region.
This includes temperature,wind patterns, and
precipitation. This change is referred to in a global
sense and concerns the earth as a whole.

The Earth's Climate in the Past
Some natural factors that have changed
the Earth's climate in the past
Changes in the Earth’s orbit
Changes in the sun’s energy
Photosynthesis
Volcanic Eruptions

Climate Change in India Contex

Finding solution
Mitigation in the energy sector
Using CNG Vehicles
Using Electric Powered Vehicles
Cleaner Diesel Engines
Hydrogen-fuelled Vehicles

Finding solution
Shifting to Renewable Energy
Using Solar Power
Using Wind Power
Using Hydropower
Using Bio Gas

Finding solution
At Individual level
By Using Eco-friendly transport
By Using Energy efficiency
By Managing waste
By Plant more tree and preserve nature
