=Climate Change=

You here a lot about climate change, on the news, in newspapers, TV shows and books. They are even making films about it. But what do you actually know about Climate Change?

Task 1: What do you already know?

 * ==== Here's a game to test your knowledge You'll need to log on to Geographyalltheway.com to play it. ====

2) What does Climate Change mean for us?
====The answer is that we do not know. There are many different scenarios, some much more dramatic than others. £In this section we will be looking at some of the threats posed by climate change. You will also be asked to decide which is the most important.====

====





====**b)** Now add a **fifth heading, "People,"** and see if you can use **the knowledge you already have** to comment on **how climate change will affect people around the world**. We will be adding more information to this page later.====

====**c)** Look at the images above. Use the internet to **find more images** that will illustrate the four headings from the WWF site. I**nsert two images per heading** into the document. Make sure you give the images a **caption** and say **where you found the photograph**.====

//The video above is a google earth tour that illustrates the causes and consequences of rising sea levels. We will watch this together in class but you also need to watch it again on your own.//

 * === Rising Sea Level ===

**c)** Add another page to your word document. Give it the title, "Rising Sea Level." Find a good image to illustrate rising sea level.

**d)** Under the photograph you are to take notes from the video above. Put your notes under the following headings.
 * ====//The causes of sea level rise.//====
 * ====//The consequences sea level rise.//====

====Make sure you include **place specific references** in your notes. This means the **names of the places** where ice is melting, the names of **areas that will be affected** by rising sea level and any **relevant data** such as numbers of people affected.====

====**e)** Whilst you are making notes, I would also like you to **add the information to a map.** I will give you a world map, add as much information to it as you can using the video above. Mark on the worst affected areas as well as the areas where melting ice will contribute to sea level increase.====

====**f)** As you learn about sea level change you will realise that many millions of people will be affected. **Towns and cities and even entire countries will be flooded, forcing people to leave their homes and jobs.** Do some research to **find out how many people will be forced to leave their homes as sea level rise affects Bangladesh.** **Where will they go?** What about New York, the Netherlands and the other places mentioned in the video. Where would the people go? Apart from making people homeless, what other affects will sea level rise have on the human population, **think about jobs and the economy of countries.**====

====**g)** One of the problems we have in understanding the issues of climate change is being able to understand **how it will affect us as individuals.** We will continue to discuss this throughout the course but I would now like you to use the information you have to **comment on how each of the four impacts can have an impact on you.** Add a subheading towards the bottom of each page that asks, **"How this will affect me."** Beneath the subheading write a few sentences to each page that begins to discuss this.====

The Effects of Climate Change:

====Using the information you have gathered so far, I would like you to write a couple of paragraphs answering the question above. In order to do this properly you answer must contain examples that illustrate why we refer to climate change rather than global warming.====
 * ==Why is this unit called Climate Change and not Global Warming?==


 * == Is there an argument for calling it Global Warming? ==

**Task 3: The Greenhouse Effect**
**a)** Open the word document used for tasks 1-4 and add a new title, "Climate change and the Greenhouse Effect." Insert the diagram above into the document.

**b)** Beneath the diagram write a few sentences explaining what the Greenhouse effect is and what is causing it.

//Remember not to use the phrase Global warming as this video does. Hey nothings perfect.//

The Composition of the Atmosphere and the Greenhouse Gases
====Almost all of the Earth's atmosphere (99%) is made up of **nitrogen** (about **78%**) and **oxygen** (about **21%**). While both of these gases play important roles in the vast number of processes that support life on Earth, they play almost no direct role in regulating the climate. This is carried out by some of the trace gases in the remaining 1% of the atmosphere which occur in relatively small amounts:====

**b)** Use the instructions on this BBC Bitesize page to help you draw the pie chart.
====**c)** Once you have drawn your pie chart, have a go at using excel to produce a similar pie chart that you can add to your word document. When using excel, you should use the actual % for each of the trace gases. You can find out the exact %'s here. ====

More about CO 2

**7)** Describe the change in the global pattern of CO2 between 1900 and 2000. Which countries have seen the greatest increase in CO2 emissions.

Can we prevent Climate Change? Can we reduce its impact?
