3. What is Climate Change?
o Climate change is the result of long-term
significant changes in our weather patterns.
o In understanding global climate changes it is
necessary to combine many disciplines, including
oceanography, meteorology, geomorphology,
geology and paleoclimatology.
o Climate change can be natural or caused by
changes people have made to the land or
atmosphere.

4. Causes of Climate Interruption

Causes
• Continental Drift
• Volcanoes
• The Earth's Tilt
• Ocean Currents

5. Causes of Climate Interruption
• Major cause of climate change.
• 97% of climate scientists agree
that climate-warming trends over
the past century are very likely
due to human activities.
• Deforestation, Burning of Fossil
Fuels, Air Pollution are the main
results of global warming caused
by humans which eventually
changes the climate.

8. Health Impact on Climate Change
The most
vulnerable people—
(i) The children,
(ii) The elders,
(iii) The poor, and
(iv) Those with
underlying health
conditions
—are at increased
risk for health
effects from climate
change.

13. Facts...

14. Facts… Urban air
pollution
causes about
1.2 million
deaths every
year.
Rising temperatures and variable
precipitation are likely to decrease the
production of staple foods in many of
the poorest regions – by up to 50% by
2020 in some African countries.This will
increase the prevalence of malnutrition,
which currently cause 3.5 million deaths
every year.

15. Facts…
Studies suggest
that climate
change could
expose an
additional 2
billion people to
dengue
transmission by
the 2080
the modest
warming that
has occurred
since the
1970s was
already causing
over 140 000
excess deaths
annually by the
year 2004

16. What Can We Do?
Think & Share ideas !
Try something on your own !
Reduce, Reuse & Recycle!
Live a Eco-Friendly Life !

17.  Use local bus or
bicycle for
movement or
you can even
walk in short
journeys!!
Some Eco-Friendly Examples!

18. Switch to Natural Power Sources
