Climate change
Climate change is caused by the
release of greenhouse gases like
carbon dioxide into the
atmosphere.
Fossil fuels like coal, oil and gas
are made of carbon so release lots
of carbon dioxide when they are burnt.

Climate change
Most of the world’s electricity is produced
by burning coal, many of our homes are
heated by fossil fuels and nearly all of the
world’s vehicles are powered by burning
oil.
Therefore every time we use electricity,
heat our homes or use a car it contributes
to the effects of climate change.

Climate change:
Effects
Climate change is already a really
serious problem for humans and
animals.
It is causing polar ice to melt and sea
levels to rise.
It is causing seasonal weather patterns
to change and increasing extreme
weather events like floods and droughts.

Climate change:
Effects
All these changes are making it more
difficult than ever for endangered
animals.
It also makes life harder for humans:
extreme weather is causing drought and
flooding in many parts of the world,
making it more difficult to produce food,
or even just to survive.

Climate change:
What can we do?
There are lots of small changes which we can make to help to
tackle climate change.
Can you suggest any?

Climate change:
What can we do?
Here are a few changes we could make:
• Walk or cycle instead of driving to school.
• Switch televisions and computers off instead of leaving them on
standby.
• Put on a jumper when you are cold instead of turning on the
heating.
• Make sure to recycle all plastic, paper and glass instead of
throwing it away.
• Turn off the lights when you leave a room.

However, it is also important that
we tell important people like the
government and big businesses
that we think climate change is
important.

It’s important that we all do our
bit by making small changes to
our lifestyle.

One way of doing this is by taking part in WWF’s Earth Hour.
On the 26th March 2011, WWF is asking everyone to switch off their
lights for 60 minutes.
In 2010 hundreds of millions of people from over 128 countries
joined in to make the biggest statement ever about climate change.

Hundreds of famous buildings
and landmarks also switched
off their lights in a show of
support.
Do you recognise these
buildings and landmarks?

This year we want to make the
event even bigger; the world’s
largest display of hope for a bright
future.
We will be celebrating WWF’s Earth
Hour at school, but you can help by
also passing the message to your
friends and family and asking them
to get involved.
Thank you
