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.

How will I do this?
• This is independent learning.
• You will research global warming using text books, “Data
sheets”, the internet and your notes from the videos that
you have been shown.
• You will prepare a detailed report following the writing
frame, ticking off the tasks as you complete them.
• You will self evaluate your work.
• You will either hand write or word process your report
(Using Word) to hand in P5 4th July.
• You can use computers in HU2 on Thursday lunchtimes.
Where will I find out what I need?
• Geog 2 Page 78-79- Basic info on causes
and effects
• Connections Page 6- Basic info
• Green house effect data sheets
• Effects of global warming data sheets
• The internet
• Using the library in your own time.

This site provides evidence from the CH4 Documentary that global
warming is not man made or isn’t in fact actually happening.
1. What is Global warming?
In section 1, describe and explain what global
warming is and how it works.
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.
Source: Solcomhouse.com
Greenhouse Effect
• 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?
• 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?
•
•
•
•
•
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
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

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
Influences on causes of
climate change
• The key areas are –
• The Sun: Variations in Solar Output
• Variations in the Earth’s orbit
• Variations in the Earth’s tilt
Some scientists believe that the
global warming we are seeing
has natural causes…
• The Sun: Variations in Solar Output
• Variations in the Earth’s orbit
• Variations in the Earth’s tilt

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

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

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

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

The effects of Climate Change
• 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.
