WHAT IS CLIMATE CHANGE?
Watch this short video by our sister agency, CAFOD (Caritas England &
Wales): https://www.youtube.com/watch?v=v8unGCTWUWI or learn
about the Greenhouse Effect using the following PowerPoint slides.
Heat from the sun shines
onto the Earth.
It passes through a
blanket of gases in
our atmosphere.
Some of the heat
energy is reflected
back into space.
Some of the heat energy
is absorbed by the
blanket of gases.
The ‘greenhouse’ gases are
essential to life on Earth. Without
them heat energy would escape
back into space.
Earth would be a
very chilly place
with an average
temperature of
-18°C !
The greenhouse gases help to keep
the temperature of the earth in
balance. This process is called the
GREENHOUSE EFFECT.
The gases work a bit
like glass in a
greenhouse to trap in
warmth.
But the earth is
getting warmer and
warmer.
WHY?
Human activities are creating
more greenhouse gases
including carbon dioxide, CO2.
As we burn more
fossil fuels, for
example, the
blanket of
greenhouse gases
becomes thicker.
More greenhouse gases in the
atmosphere mean that more
heat energy is absorbed.
We call this increase
in the temperature
of the earth
‘global warming’.
The world’s top 10 warmest years
on record have occurred since 1998.
(Records began in 1858)
CALL TO ACTION
Caritas Australia is working with many
more communities to help people
affected by climate change. But Pope
Francis also reminds us that
Governments and every person need
to be kind and fair to everyone and to
our planet!
“Humanity still has the
ability to work together in
building our common
home.” [13]
WHAT CAN WE DO?
We can choose simpler and more
sustainable ways to live our life.
For example, we can:
• Reduce the amount of waste we
produce, and make sure to reuse
and recycle too
• Switch to renewable energy
sources
• Take public transport, walk, run,
cycle…
• Plant trees
• Turn off lights when not in use
What other things can you think of?
