Concise slides for helping children understand about climate change- why it happens, how it is affecting us and how can we prevent it.

2. Climate change refers to significant, long-term changes in the
global climate.
The global climate is the connected system of sun, earth and
oceans, wind, rain and snow, forests, deserts and savannas, and
everything people do, too. The climate of a place, say New York,
can be described as its rainfall, changing temperatures during the
year and so on.
But the global climate is more than the “average” of the climates
of specific places.

3. The greenhouse effect
is a process that
occurs when gases in
Earth's atmosphere
trap the Sun's heat.
This process makes
Earth much warmer
than it would be
without an
atmosphere. The
greenhouse effect is
one of the things that
makes Earth a
comfortable place to
live.

4. Definition: Global warming is the slow increase in the average temperature of the
earth’s atmosphere because an increased amount of the energy (heat) striking the
earth from the sun is being trapped in the atmosphere and not radiated out into
space.
The problem we are facing today
Without our atmospheric greenhouse the earth would be
very cold. Global warming, however, is the equivalent of a
greenhouse with high efficiency reflective glass installed
the wrong way around.
Today, the problem is not that too little sun warmth is
reaching the earth, but that too much is being trapped in
our atmosphere.
So much heat is being kept inside greenhouse earth that the
temperature of the earth is going up faster than at any
previous time in history.

8. Because all systems in the global
climate system are connected,
adding heat energy causes the
global climate as a whole to change.
 Temperatures are rising
continuously
 More droughts and heat waves
 Hurricanes becoming more
stronger and intense
 Artic becoming ice- free
 Sea levels are rising
 Changes in precipitation
patterns

9.  Burning fossil fuels
When we burn fossil fuels like coal, oil and gas to create electricity or
power our cars, we release CO2 pollution into the atmosphere.
 Deforestation & Tree-Clearing
Plants and trees play an important role in regulating the climate
because they absorb carbon dioxide from the air and release oxygen
back into it.
 Agriculture & Farming
Animals, particularly livestock like sheep and cattle, produce methane,
a greenhouse gas. When livestock are grazed at a large scale, as in
Australia, the amount of methane produced is a big contributor to
global warming. 9
