If We arent Changing the Climate, then Who is?

What is Climate Change?

! Life on earth is possible because of the sun and the

delicate atmosphere that surrounds our earth.

! Our atmosphere traps the heat we need to survive.

! The most important gas in our atmosphere is CO2,

Carbon Dioxide.


3/31

So Whats the

Problem?

! Our burning of fossil fuels and

our conversion of land for

housing and agriculture has

released unprecedented

amounts of Carbon Dioxide

into the atmosphere.

! The Carbon Dioxide has

trapped too much heat in our

atmosphere, which is making

our world heat up.

Smokestack emitting unimaginable amounts of carbon into atmosphere

How does Climate

Change affect us?

A warmer world could result in

many negative e#ects.


5/31

Drought

Drought is one of the e#ects of climate

change. Warmer weather could dry up

water deposits and interfere with farms,

food rations, and cause dehydration and

starvation.


6/31

Melting Glaciers

! Just a few degrees of

increased temperature can

cause glaciers to melt,

damaging the ecosystem

greatly.

! Polar Bears and other arctic

animals lose their habitats and

be unable to access their

hunting grounds.

Polar Bear habitats are fragmented


7/31

Freak Weather Events Climate change may cause abnormal, extremely destructivestorms that wreak havoc across entire states or provinces.

A large thunderstorm forms quickly and wreaks havoc on community


8/31

Forest Fires

! Forest fires are also caused by

global warming.

! Increased temperatures make

flames easier to ignite.

! Forest fires destroy homes,

ecosystems, and add more

carbon dioxide to the

atmosphere.

Forest Fires in Colorado are deadly and unstoppable


9/31

Flooding

! Flooding is the result of glaciers melting.

! The seawater is contaminated, and may contaminate a

citys water supply.

! This may result in the spread of disease.

Floodwater makes it difficult for people to move around.


10/31

SmogSmog is caused by intensive coal

burning in the city. It may cause similar

e#ects as smoking to the lungs, as it

contains many artificial chemicals andsubstances.

Large amounts of smog obscure what looks like to be a beautiful city

The Million Dollar Question: Are we causing climatechange?

Or is nature causing climate change?


12/31

Natural Causes of Climate Change


13/31

Natural Processes are

Not Many

Volcanoes can release carbon dioxide

into the atmosphere, but only rarely.

Volcanoes do not erupt very often!


14/31

Many say that our own sun is causing climate change. It is,

but it is in fact supposed to be causing Earth to cool down.

The amount of solaractivity is actuallydecreasing, which

should in theory makeEarths temperature

increase.

Strangely, this isnt the

case. Earths

temperature seems to

be steadily rising every

year. This means that

the Sun is not what is

causing our temperature

to rise.


15/31

Ocean Currents and

Continental Drift

Some argue that ocean currents and

continental drift also cause climate change.

However, the amount of temperature increase

is unlikely to be high.


16/31

Natural Processes Conclusions

! Of all the evidence that natural processes create climate

change, the only reasonable one is Volcanic Eruptions.

However, eruptions do not release a ton of carbon or

nitrogen into the air; it only happens once in a while and

is dwarfed by what we put into the atmosphere.


17/31

Man-Made Causes of Climate Change


18/31


19/31

Its not them, its us.

Our machines are capable of

emitting large amounts of carbon

dioxide into the atmosphere.


20/31

Fossil Fuel EmissionsThe burning of fossil fuel for energy releases a huge amountof carbon into our atmosphere. This graph shows that


21/31

Motorized

Transportation

The increasing need for transportation

over a large area requires the use of

vehicles. Vehicles emit large amounts

of carbon into the atmosphere.


22/31

Deforestation

We need more land for factories

and living quarters. Cutting down

trees, we remove one of the natural

absorbers of carbon. This can

increase the amount of carbon in

the atmosphere and also decrease

the amount of clean air we breathe.


23/31

Agriculture

The clearing of land for agriculture

increases the amount of methane and

carbon in the air as waste products of

various animals tend to waft up into the

atmosphere, further trapping in heat.


24/31

Use of Fertilizers

! Fertilizers contain inordinate

amounts of nitrogen, which is,

although vital for the growth of

various plants, eventually taken

up the the atmosphere. This

may induce acid rain anddamage many ecosystems.


25/31

Human Processes Conclusion

! Humans have indubitably caused this planet to heat up

exponentially through our use of fossil fuel as an energy

source and our decisions for transportation.

! Our use of coal and other fossil fuels have heated up ourhomes, but have also heated up outside.

! Our use of land causing deforestation has caused a rise

in carbon dioxide levels in the sky.

! We need to stop this destructive behaviour.


26/31

The Trillion Dollar Question: How do we stop climate change?

We have to save the planet that we

were given responsibility for.

It is our world, and we need to take care of it.


27/31

TransportationWe can ride bikes or take transit

as those are all greener

alternatives to driving to work.


28/31

Energy Use

! By reducing the energy we use

we can also reduce the amount

of fossil fuel needed to be

burned, therefore reducing the

amount of carbon emissions.

Three rs, all reduce.


29/31

Consume ResponsiblyDo not over consume, especially on meat

products. The grazing of these animals

usually cause a lot of carbon emissions

with their waste.


30/31

We can all make a

difference.

We can all care for the world

that we have been given.

Not only that, we should.
