Local Actions, Global affectsLocal Actions, Global affectsGlobal warming debate
Learning ObjectivesLearning Objectives
• To outline the arguments for and against global warming
• To understand other possible reasoning for temperature increase
• To evaluate evidence that proves and disproves the theory
Global Warming InvestigationGlobal Warming Investigation• 1. What is Global warming?• In section 1, describe and explain what global warming is
and how it works.• 2. Are humans to blame?• In section 2, explain the arguments connecting the
influence of human actions and the increased risk of global warming.
• 3. Is it really just nature?• In section 3, examine and explain arguments that disagree
with human actions and the increased risk of global warming are being influenced from another source.
• 4. What is the future going to be like?• In section 4, describe, explain and evaluate the potential
effects of increased global warming in the future, including social, environmental and economic effects
• 5. In my opinion, I think….• In section 5, evaluate and conclude your own opinion on
why global warming may be happening and the effects for the future. In this section also include what can be done to combat global warming and how successful you think each of these plans will be.

Teacher Comments:
GRADE Targets

Gases in the atmosphere such as carbon dioxide, methane, nitrous oxides and CFC’s (Greenhouse gases) trap the radiation from the sun that is reflected back from the Earth.
solcomhouse.com
• The gases in the atmosphere act like a blanket around our planet which traps in heat, making the temperature rise.
• This is called the Greenhouse Effect and is a natural process that keeps the planet warm and sustains life.
• If the greenhouse effect didn’t exist, the average temperature on earth would be around -18ºC.

Is global warming really happening?Is global warming really happening?
• What evidence is there that global warming is happening?
• We can look at changes in temperature, Sea levels, large pieces of Ice, known as Glaciers and Ice caps
• You will need to draw out the grid like the next slide and then watch the next 3 video clips – make notes on each section.

2. How are humans responsible for producing more Carbon Dioxide?2. How are humans responsible for producing more Carbon Dioxide?
• What are the major sources of carbon dioxide production?• Burning fossil fuels• Factories• Having lots of cars on the road• Cutting down trees
For this question, you need to make the points, give examples to support your points and then explain with as much detail as possible
For this question, you need to make the points, give examples to support your points and then explain with as much detail as possible
Are Humans to blame?Are Humans to blame?
In this question you are answering yes –
You must now use PEEEL to explain, give reasons and explore why this is the case
TO answer this question think and consider the following things for your response –
How has life for Humans changed in the last 100 years?
What influence and impact have Humans had on the amount of Carbon Dioxide being produced and why is this important?• How and why has this change happened –
• Increased standard of living and how.
• Increased demand and use for natural resources
• Increased electricity use
• Increased heating
• Changes in Food around the world
• Use of transport
• Increased holidaying
• Development and changes in industry
• Use and demand of fossil fuels
• Destruction of the rainforest / Deforestation
• World population change
• How do these things influence and change carbon dioxide
• Explain, Explore, give examples and evidence and evaluate
• Are these changes equal across the world?
• Are some countries / people more responsible than others.
Q3. Is it just nature?In this question, you are required to give evidence and
explanation showing that the warming of the Earth is due natural reasons and not humans.

• 4 clear reasons why the Earth is warming due to natural causes
• 1. The output of the sun’s energy changes • 2. The orbit of the Earth around the sun changes• 3. The tilt of the Earth alters making it closer and further away
from the sun• 4. The natural wobble of the Earth causes it to become closer
to the Sun.
• Evidence to support this – • Historically how has climate changed with no input from
humans?
TO support with this question we will watch the clip about natural causes again and then short clip from
the global warming DVD

• The key areas are – • The Sun: Variations in Solar Output
• Variations in the Earth’s orbit• Variations in the Earth’s tilt

Climate Change
If the greenhouse
effect becomes
stronger, it could make the Earth warmer
than usual.
Even a little extra warming
may cause problems
for humans, plants,
and animals.

Sea levels around the world could rise.
Cities on coasts would flooding.
What if the Earth heats up?

Temperate places that now receive frequent
rain and snowfall might become hotter and
drier, leading to more drought.
What if the Earth heats up?

Frequent periods of drought would make
it hard to raise crops for food, leading to
famine.

Forest fires could occur more often.

Plants and animals unable to take the heat
may go extinct, and be replaced by heat
tolerant species.

Hurricanes, tornadoes and other storms
caused by changes in heat and water
evaporation might occur more frequently
and be more intense.

In the UK, we expect that because of climate change:
• Temperatures will increase. • Winter rainfall will get heavier, increasing the risk of flooding.

• Summer rainfall in the UK may reduce considerably, creating pressure on water resources.
• Sea levels will rise due to melting ice caps, leading to further coastal erosion and flood risk.

Scientists worry that climate change is progressing so rapidly that, within
decades, humans may be helpless to slow or reverse the trend.There is a threshold where a slight
rise in the Earth's temperature can cause a dramatic change in the
environment that itself triggers a far greater increase in global
temperatures.
This is the ‘tipping point’ beyond which really dangerous climate
change is likely to be unstoppable.
