The Big Picture:

KQ : How does global warming affect the earth?

LO:• To distinguish between global warming and the ozone layer• To explain the causes of global warming• To suggest some possible solutions to global warming and justify your own

opinions.

STARTER: Who’s right? Why? Write your own definition of global warming

The reason why global warming is happening is because there are holes in our ozone layer

What??? I thought global warming was because the atmosphere was getting thicker

TIF: Is there a difference between the ozone layer and atmosphere?

Atmosphere • The sun produces infrared heat (IR) to

warm the earth• Some of this heat remains in the

earth and some is reflected back into space

• The atmosphere protects the earth from getting too much IR

• As Co2 emissions increase, the atmosphere gets thicker so the excess IR cannot escape

• This causes the earth to heat – global warming

TIF:• How can human activities increase

co2 in the atmosphere?

Ozone Layer• The earth is also surrounded by the

ozone layer• This protects the earth from ultra

violet light (UV) coming from the sun• This light has no heat• Man made products that uses CFC

gases from things like aerosols damages the ozone layer

• Over time, this created a hole which has exposed the earth to direct UV

TIF: • Where is this hole in the ozone layer?• Why is this harmful to humans?

Global Warming

The ozone layer is the same as the atmosphere?

Global warming is to do with Infra Red?

UV light from the sun gives us heat?

Too much CO2 can thicken our atmosphere ?

Holes in the ozone layer cause global warming?

TRUE FALSE

I don’t care about Global Warming. We can’t stop it anyway…I like the sunshine and long hot summers. I say, bring it on!!

Do you agree or disagree?

How to justify your opinion in writing:

1. Explain what your opinion is

2. Use an example to explain why you think that. This is the justification!

Step 1 – 1 point and a suitable example to justify the point: Swap BooksStep 2 – add a second point to support the same side and a suitable example to justify the point: Swap books

Learning Goals

• You must be able to distinguish between global warming and the ozone layer

• You should be able to explain the causes of global warming.

• You could be able to suggest some possible solutions to global warming and justify your own opinions.

Key words challenge…match the keywords to the correct statements and write them in your glossary

As you watch the videos write short notes to fill in your table

Global Warming

Causes of Global Warming Effects of Global Warming Possible Solutions

Burning of fossil fuels Changing patterns of precipitaion

Electric cars, hybrid

Greenhouse effect Diseases like malaria returning to places where it was eradicated

Use more energy efficient shower

Solar radiation Extreme weather events – floods, droughts, heatwaves, more powerful hurricanes etc

Carpool

Deforestation Species extinction Recycle, plant a tree, etc

The Greenhouse Effect1) Heat and light energy reach us from the sun…

2) …a lot of this heat is reflected off the Earth’s surface…

3) …some of the heat escapes back into space…

4) …while some of it is reflected back to the Earth – this is called The Greenhouse Effect

Global warming at a glance...

Global warming is the consistent increase in the temperature of the earths atmosphere
