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

Teacher Comments:

GRADE Targets

You will self assess your work and comment on what you have done well and what you could do to improve it.

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.

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

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.

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.

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.

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.
