Climate Change and Sea
Levels
BY SP
Revision
Introduction
• Many people are interested in climate change and how a changing climate will affect the ocean. With the
majority of Americans living in coastal states, rising water levels can have potentially large impacts.
Scientists have determined that global sea level has been steadily rising since 1900 at a rate of at least 0.04
to 0.1 inches per year.
Sea Level
• Sea level can rise by two different mechanisms with respect to climate change. First, as the oceans warm
due to an increasing global temperature, seawater expands—taking up more space in the ocean basin and
causing a rise in water level. The second mechanism is the melting of ice over land, which then adds water
to the ocean.
Climate Change
• Climate change affects us all, but how do designers approach the problem of rising water levels in the UK
and the Netherlands? The Thames Barrier was built to protect London, keeping the water out in times of
high tides and storms. But as sea levels rise, the barrier is being raised more frequently. Developers are
being forced to consider brownfield sites for housing as demand grows, but these sites are often at risk of
flooding. Architect Richard Coutts' company has an innovative approach to living with water. Their designs
work with rising water levels instead of against them.
Quick Quiz-Sea Levels
What is the prediction on the increase of the sea level per year?
a)
0.06-1.5 Inches
b)
0.04-0.1 Inches
c)
3-4 Inches
Which of these is a hard engineering technique
a) Beach Nourishment
b) Gabions
c) Dune regeneration
How does climate change affect sea levels?
a)Sun evaporates the sea and global warming causes sun to get warmer evaporating more water.
b)The sun burns holes in the sea bed which water can exit through.
c)The cold weather makes more clouds which means more rain.
Quick Quiz-Climate change
• Which of the following is not evidence provided for climate change?
a) Weather recordings
b) Fossils
c) Animal Behaviour
Land which is most at threat from rising sea levels is?
a) Coastal land
b) Land on a flood plain
c) Land above 100m
Which of these is not a natural cause of change to our climate?
a)b) Pollution from vehicles
c) Volcanic activity dust particles released in an eruption can disrupt the atmosphere.

plots of land are cultivated temporarily, then abandoned
and allowed to revert to their natural vegetation while the
cultivator moves on to another plot.
*Mining and Industry: the process or industry of obtaining
coal or other minerals from a mine.
*the commercial organisation of holidays and making
tracks for this
*Wood cut down to be used as fuel.
*To make space for breeding of animals.
Why Is It Better To Buy Local Food
By CK and JA
It is better to buy local foods because the food looks and tastes better and is going to
be more fresh.
Local food is better for you because the less time it has taken to be produced and to be
eaten by you the better.
It is also a waste of CO2 because by getting the food transported to you then you are
causing damage to the environment.
Buying local food costs less because it costs a lot to get it transported from other
countries.
By buying local food you are supporting local farmers today by helping to ensure that
there will be farms in your community tomorrow.
Local food is more safe because it is less likely to be messed with.
Tropical Rainforest
The tropical rainforest is a biome with a constant temperature and a high rainfall. The level of humidity and density of the vegetation give the
ecosystem a unique water and nutrient cycle. Rainforests around the world are threatened by human expansion.
A tropical rainforest biome is found in hot, humid environments in equatorial climates. They contain the most diverse range
and highest volume of plant and animal life found anywhere on earth.
Questions
What is the rainforest water cycle?
What is the rainforest nutrient cycle?
Name and explain three tropical rainforest plant
adaptations
_______
_______
_______
_______
Label the Layers
Answers
What is the water cycle?
The roots of plants take up water from the ground and the rain is
intercepted as it falls - much of it at the canopy level. As the
rainforest heats up, the water evaporates into the atmosphere and
forms clouds to make the next day's rain. This is convectional
rainfall.

Revision - Birth and Death Rate
Births – usually measured using the birth rate. Birth rate is the number of live births per one thousand of the
population per year.
Deaths – usually measured using the death rate. Death rate is the number of deaths per one thousand of the
population per year.
The rate of natural increase is given as a percentage, calculated by dividing the natural increase by 10. For
example, if the birth rate is 14 per 1,000 population, and the death rate is 8 per 1000 population, then the
natural increase = 14 - 8 = 6. So the natural increase is 6 or 6/1000.
The natural increase is calculated by subtracting the death rate from the birth rate.
An MEDC is a more economically developed country.
An LEDC is a less economically developed country.

Recycle
• The resources on the Earth are limited. It is important that the things we
do now do not make things difficult or impossible for future generations.
To achieve sustainable development, we need to balance these things
carefully.
• Recycling is an important way to help us achieve sustainable
development.
• We can recycle many resources, name a few:
Glass, metal, paper, plastic
Reuse
Could the product could be used for something else so you don't
need to throw it away. Take an existing product that’s become
waste and use the material or parts for another purpose, without
processing it.
For example: Plastic bags, Water bottles etc

How to change the Death
Rate
What is Death Rate?
• The death rate is the ratio of deaths to the population of a particular
period of time, usually calculated as the number of death rates per
one thousand people per year.
• “Improved diets have reduced death rates”
How to increase death rates
There are many ways of increasing death rates such as:
• Not giving people food
• Spreading diseases
• Burn lots of fuels to increase air pollution
• Not have enough hospitals
How to decrease death rate
There are many ways of decreasing death rates also, such as:
• Stop global warming
• Provide better food (better harvests)
• Improved hospitals
• Better sanitations
