1. Can Our Climate Change?

2. Lesson Objectives
• To know our climate does change
• To understand this is the result of both
human and physical reasons
• To be able to develop an opinion on who
is to blame

3. Temperatures
• Temperature rising, Interactive : here
• You will see different line graphs
• For EACH one describe the trend
• when was it the highest?
• When was is the lowest?
• What does it start on?
• What does it finish on?

4. Who is to blame for the
temperature increase?

5. Solar Activity
• Also how
much heat
the sun
gives us
changes,
affecting
our
climate
• here

6. The Earth’s Orbit
• How
close to
the sun
we are
affects
our
climate
• here

7. Tectonic Movements
• Movements in the
earth’s tectonic
plates will change
the ocean
currents. This in
turn will change
the climate of
some areas.
• here

8. Volcanic Activity
• Volcanoes erupt on
a regular basis
• They blast ash and
dust into our
atmosphere,
reflecting the
sun’s energy
• They also release
huge quantities of
CO²
• here

9. Reflection from the ice
• Huge ice sheets can cover large areas of the Earth.
The white colour reflects the sun’s energy
• here

10. Industrial activity
• Burning fossil
fuels releases
carbon
dioxide into
the
atmosphere
• They are used
in power
stations to
create
electricity
• Here
Fossil fuels are coal, gas and oil
They are the remains of living plants and
animals from millions of years ago
Burning them releases that stored CO²

11. Transport
• Cars, trains, planes
all use fuel
• Fuel is made from oil
• Using transport that
runs on petrol or
diesel releases huge
quantities of CO²

12. Human activity
• Humans breath in
oxygen, but
breathe out carbon
dioxide
• There are more
humans on the
planet than have
ever lived before
• Over 7 billion
people!

13. Plenary
• Who is to blame?
• You decide
• Write a paragraph stating, now that you
have seen the evidence, who you believe
is to blame for our rising temperatures
