change
Is caused by greenhouse gases trapped
in our atmosphere. These gases are
caused by driving cars, burning coal
and cutting down forests.
Let’s start this lesson by learning about “Changing climate”.

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.

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.

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.

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.

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.

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.
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.
plants
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.

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.

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.
