1. The human-induced climate change
is already occurring
and that future change is inevitable.
2. This summer's heat is
a long-term warming trend

one of the hottest summers

5. Global warming is
A rise in temperature of the Earth
caused by emissions
of carbon dioxide
and other heat-trapping gases
that are emitted primarily
by the burning of fossil fuels
and the clearing of forests.
These gases remain in our
atmosphere for decades
or even centuries.
6. The atmosphere around us is made up of
Some of these gases function like the
of a greenhouse:
they let some radiation from the sun in
but also retain heat
in the atmosphere, that is:
they don't let all radiation back out.
As a result of this natural effect, it is
warmer on Earth than it
would be without these heat-trapping
gases.This is called the greenhouse
of certain gases to
8. World's leading climate scientists
the Earth's temperature is rising
and that its climate has changed
over the last century.
The scientific consensus is clear that
rise in temperature and change in

9. Causes of global warming
• aerosol emissions
•overuse of energy
• economic growth
• land use changes
•Burning of fossil fuels
10. What is Ozone?
Ozone is a colorless gas.
Chemically, ozone is very active;
it reacts readily with
a great many other substances.
Near the Earth’s surface,
those reactions cause rubber to crack,
hurt plant life,
and damage people’s lung tissues.
also absorbs harmful components
of sunlight, known as
“ultraviolet B”, or “UV-B”.
High above the surface,
above even the weather systems,
a tenuous layer
of ozone gas absorbs UV-B,
protecting living things below.
11. ozone hole
Each year for the past few decades
during the Southern Hemisphere spring,
chemical reactions involving chlorine
cause ozone in the southern polar
region to be destroyed rapidly and severely.
This depletion is known as the “ozone hole”.

and higher-intensity tropical storms

The ranges and abundance of plants and animals
could change dramatically under changing
climate conditions, and some of them are
likely to be unable to adapt or migrate
to new locations.

19. Sea level rise
Sea level could rise by
3.5 to 34.6 inches between 1990 and 2100,
making coastal groundwater saltier,
endangering wetlands, and inundating
valuable land and coastal communities.

• Burning of fossil fuels,
• cement manufacture,
• deforestation and
• other land-use changes
27. Carbon dioxide (CO2) is one of those
heat-trapping (greenhouse) gases
that have increased significantly
in atmospheric concentration since
pre-industrial times and thus has
raised the greatest concern.
