4. Welcome to Changing Climate
But before we do, let’s reflect on what we learnt in our last lesson…
During this lesson we will be exploring…
Changing climate

5. In our last lesson we learnt that climate change
Is about changes happening to our planet and to our plant life, mountain glaciers and sea levels.
Is important because it will have an impact on us all.
In our last lesson we learnt that climate change
Is caused by greenhouse gases trapped in our atmosphere. These gases are caused by driving cars, burning coal and cutting down forests.

6. Let’s start this lesson by learning about “Changing climate”.

7. Cause: Rising sea level
Rising sea levels are a concern for many flat and low lying countries, islands and cities. This includes Pacific Islands such as Tuvalu, Marshall Islands, Nauru and Kiribati.
Greenhouse gases in our atmosphere are raising sea levels by:
1. Making the oceans warmer, which is expanding water and creating more and therefore raising the sea level each year.
2. Melting glaciers, polar ice caps and ice sheets moving into the ocean are raising the sea level.

8. Impact: Rising sea level
It is predicated that by 2150 many Pacific islands, in particular Tuvalu, Marshall Islands, Nauru and Kiribati will be partially or mostly underwater due to rising sea levels.
The impact of rising sea levels on small islands like these, mean people affected will eventually lose their houses, schools, churches, their history and places where their cultural traditions and practices were born.
They will leave all this behind with future generations not experiencing these places and histories first hand.

9. Cause: Floods and droughts
Climate change is expected to create more rainfall, resulting in floods for some countries and less rainfall causing droughts for others.
1. During the water cycle process, water is evaporating faster due to a warmer climate. More water evaporating in the sky means more snow in a snowfall, more water in a downpour and therefore more flooding.
2. Although there might be more rainfall, this may not happen regularly. This means there are longer periods of sun, no rain, lack of moisture in the soil and therefore causing droughts.

10. Impact: Floods and droughts
The impacts of flooding and droughts can hugely affect us all. This can include loss of human and animal life, destruction of property, crops and wildlife, the spreading of water pollutants, metal and debri, lower levels in reservoirs, lakes and ponds and poor soil quality and more wildfires.
Floods impact both individuals and communities and have social, economic and environmental consequences. What we must remember is that climate change is affecting all living things on earth.

11. Changing environments
Cause:
Changing environments
In the last 100 years global temperatures have risen to 0.8 degrees, with most of the rise happening in the last 40 years due to mass production, farming, coal burning and deforestation.
0.8 degrees may not seem like a big temperature rise but in the past, a one to two degree drop was all it took to plunge the earth into the Little Ice Age.
A five degree drop was enough to bury a large part of North America under a towering mass of ice 20,000 years ago.

12. Changing environments
Impact:
Changing environments
sunlight
With the planet’s climate becoming warmer each year, animals and plant life have begun to shift themselves from their environments to a more suitable place or climate.
plants
Some plants and animals may need to move further north to cooler locations and higher elevations, or in some cases closer to water or warmer locations.
animals
Warmer water and increased ocean acidity has already had an impact on coral reefs, which could see many coral fish and other coral sea creatures disappear.
humans
Every plant, animal and sea creature plays a role in their ecosystem but losing one species can affect many others, including humans.

13. How we can help? change the climate
The best way we can help change climate change is to burn less fossil fuels. One thing we can do to help this is to walk, bike or take public transport when we travel. The fewer cars on the road the fewer fossil fuels we burn.
Other things that will help is less fracking or deep sea drilling, smoke or emissions from industrial places or factories, using chemical solvents and cutting back on anything that creates smoke or soot.
Reducing emissions (particularly methane, tropospheric ozone, hydrofluorocarbons and black carbon) could possibly prevent the rate of sea level rise by approximately 25 to 50 percent and give better air quality.

14. Let’s reflect on what we have learnt so far…
As we have seen, climate change is caused by specific things, impacting in particular ways and calling us to take action and help in different ways
Let’s reflect on what we have learnt so far…

15. What have we learnt so today?
Climate change
Is caused by greenhouse gases trapped in our atmosphere and warming the planet. This is creating warmer oceans, melting polar ice caps causing oceans to rise and causing floods and droughts.
Impacts place, culture, ecosystems, wildlife, animal life and human life. An impact on one species will affect many others, including humans.
Can be improved if we burn less fossil fuels, less fracking, less emissions from factories and cutting back on anything that creates smoke or soot.

16. In the next lesson Art and climate change we will learn about artists who have responded to climate change through art.
We hope you enjoyed learning about more about climate change and how we can help.
