1. Have a look at the diagram

This figure shows profiles of CO2 concentrations and temperature over the last 400,000 years.

Describe the patterns you can see.  How do the two profiles vary?  What has happened to the CO2 concentrations in recent time?

2. Check out your own country!

a) Classify the energy sources in the bar diagram as fossil fuel or non-fossil fuel ("alternative") energy sources.  

b) Find out which sources of energy are used in your country. Classify them as fossil or non-fossil fuel energy sources.  

c) Try to make a diagram similar to this bar chart for the energy consumption in your country.

3. Check out your local environment!

a) Find out if there are buildings in your local area which use other sources of energy than those you listed in your answer to Question 2.

b) Write a little bit about alternative sources of energy that could be used in your country or local area in the future.

 

 

4. Do research in your local area and on the Internet!

a) Go to the page http://www.climatehotmap.org/. Here you will find a map showing signs of change that may be caused by the increased greenhouse effect in different parts of the world. Have any such changes been recorded in your country?

b) Talk to some adults (for instance your grandparents) about how the climate was when they were young. When did the flowers come out in spring? Did it snow in the winter? Do they think the climate has changed since they were young?

c) What might be the problems with using people's memories of past climate to assess climate changes?
