4. Global warming is
the increase in
average temperature
of the oceans and
atmosphere, both
observed and
predicted.
INTRODUCTION
5. Naturally occurring greenhouse
gases have a mean warming effect of
about 33 °C (59 °F).
Water vapor 36–70 %
Carbon dioxide 9–26 %
Methane 4–9 %
Ozone 3–7 %
Clouds
GREEN HOUSE EFFECTS
6.
7. Natural Causes
• Beyond our Limit
Man-made Causes
• As Much As Possible
MAJOR CAUSES
8. Methane gas
Sunspots
Arctic Tundra
Water Vapor
Permafrost
NATURAL CAUSES
10. Increased in Sea Level
Melting of Glaciers
Changed in Climate
Long summers
Effects on plants and
Animals
Skin Cancer
Asthma
EFFECTS
11. The ozone layer or ozone
shield refers to a region
of Earth's stratosphere
It absorbs most of the
sun's UV radiation hence
work as a Protective
Shield
Diseases of Skin
Plants will be Damage
Life cycle will be
disturbed
OZONE LAYER
12. Hottest year was 2010
$100 billion of damage
was caused by
hurricanes hitting the
U.S. coast in 2005 alone.
It is also projected that
15-37% of all plant and
animal species could be
wiped out by global
warming by the year
2050.
STATISTICAL FACTS
13. Up to 300,000 people a year
will die –partly from the spread
of tropical diseases.
The average global air
temperature rose between 0.5
and 0.74 degrees C during the
past century.
An average 2 degree C
warming is predicted by 2100.
STATISTICAL FACTS
14. Threats to Global Economies
Natural Disasters
Animal Habitats
Certain Species extinction
Earth Dries Up and Increase in Deserts areas
Shortage of food
FUTURE WORRIES
15. CNG and hydrogen operated
vehicles should be used.
More no. of trees should be
planted.
Chimneys in the Industries
should be upgraded so that
most of the effluents should
get filtered down there.
Climate Policy
Personal Action
HOW TO OVERCOME PROBLEM?
16. Global warming is
caused by natural and
anthropological
activities
Realize it as Global
threat
Collective Efforts are
needed
Big economies have
to contribute for the
most part
