The Great Bristol GA 6th Form
Competition 2011
A Decision Making Exercise
What will happen when the Mare of all Super floods
hits the Western(on) world?
OR
The future management of the Somerset coastal zone
A Top tip
• The information you are about to receive is vital
to your success
• So make some notes as you will not receive a
copy of this PowerPoint
Can you ever make a decision? (My mum 1996)

A key element of geography and the working world is decision making
The key is..
Be informed. Read up to give you breadth of understanding of the SEEP
points (Social, Economic, Environmental and Political)
Then you can make an informed decision which will allow you to PEE (a
great relief)
Identify your social, economic and environmental
the sustainability factor
Points and consider
4. Expand and explain your points
5.
Support them with Evidence
6.
Finally see the complexity ‘However’, Recognise your weaknesses and
prepare your counter arguments
What is climate change?
1.
A natural process by which the earth’s climate changes over time
Has it got anything to do with the greenhouse effect?

The Greenhouse effect is a natural process
Sun’s energy enters atmosphere as short wave ultra violet solar
radiation
About half of this solar energy is absorbed by earth
The rest is reflected off the earth’s surface as long wave infrared
radiation
The heat of infrared radiation is of a wavelength which is naturally
absorbed by "greenhouse gas molecules" in the upper atmosphere
such as water vapour, carbon dioxide, ozone and methane.
These molecules absorb some of this radiation and readmit it in all
directions
The effect of this is to warm the earth’s lower atmosphere
Without the greenhouse effect Life on earth would eb very diifernt
What could happen to sea levels in the future?
What could happen to the ice?
Who is already being Affected?
•
The Maldives being a
fragile low lying small
island ecosystem, is
very vulnerable to
climate change and its
associated impacts
especially the predicted
sea level rise.
•
Although the Maldives
contributes minimally to
the global greenhouse
gas emissions: 0.001%
(MHAHE 2001), it is
among the most
susceptible to impacts
of the changes in
climate.
What is the general trend shown in the graph?
Use figures to describe the trend.
Describe what has happened to sea levels over time
A map of the UK
after a sea level
rise of 84 metres 275 feet.
This is what would
be left of the UK if
all the world's ice
melted.
Where would you
want to live?
Where is a place you
would not want to live?
Why should I care?
• The anticipated range of
relative sea-level rise by the
2080s (relative to the 19611990 mean) is 20-80 cm in
south-west England
Somerset risk areas

“Threat of coastal flooding in BurnhamOn-Sea to be debated”
Coastal Group chairman Humphrey
Temperley added: “Coastal erosion is
nothing new – communities have suffered
its effects throughout history and it will go
on happening. We need to look now at
how we can cope with it over the next 100
years, given what we know about the
resources that will be available and how
the coast will change.”
What about the local impact?
