What is happening?
Question ..................
What is your understanding of climate change?
Share your ideas with the person beside you.
What is climate change?
Climate change is the result of changes in our weather patterns because of an increase in the Earth’s average temperature. This is caused by increases in greenhouse gases in the Earth’s atmosphere. These gases soak up heat from the sun but instead of the heat leaving the Earth’s atmosphere, some of it is trapped, making the Earth warmer.

What causes climate change?
Increase in greenhouse gases, as a result of an increase in human activity.
Some of the activities undertaken: burning fossil fuels (ie coal) some types of farming activities cutting down trees and clearing land decomposition (breakdown) of food, plant
wastes and sewerage production of goods and services.
Australia’s perspective
In Australia, greenhouse gas emissions come primarily (70%) from the energy sector.
Our biggest offenders are electricity generation, burning coal and road transport.
Australia generates only 1.5% of total global greenhouse gas emissions.
Australia is one of the world's biggest polluters on a per capita basis.

Are we really to blame?
There are a large number of skeptics of climate change and global warming issue.
However, there is scientific evidence that humans are causing climate change.
Do a Google search to see differing views.
What are the effects of climate change?
The Earth's temperature will keep rising. This will cause more heatwaves, longer
droughts, more storms, stronger cyclones, higher sea levels and less usable water all over the world.
(Black Saturday/Victorian bushfires, Cyclone Larry, Hurricane Katrina, severe hailstorms in Melbourne, winter heatwaves)
Also affecting our wildlife, native plants and eco-systems and natural wonders

Predictions ........
Best estimates are that by 2030 Australia will face:
a further 1ºC of warming in temperatures up to 20% more months of drought up to 25% increase in days of very high or
extreme fire danger increases in storm surges and severe weather
events.

What can we do?
Recycle – not only our rubbish, but also our toys, books and clothing
Save energy – turn off power Conserve water resources Don’t use the car – take public transport,
walk or ride a bicycle Plant a tree
