• Question 1
  Scientists representing the UN's International Panel on Climate Change predict that by the end of the century temperatures could rise by as much as:
  
  1. 3 degrees Celsius
  2. 5 degrees Celsius
  3. 5.8 degrees Celsius
  4. 6.5 degrees Celsius

• Question 2
  What has been the average global temperature change over the last 100 years?
  
  1. An increase of about 2 degrees Celsius
  2. An increase of about 1 degrees Celsius
  3. An increase of about 0.5 degrees Celsius
  4. An decrease of about 1 degrees Celsius

• Question 3
  The greenhouse effect refers to:
  
  1. A global temperature increase due to the number of greenhouse being built, especially in the industrialised world.
  2. A naturally-occurring process which keeps the Earth warm enough for life to be possible.
  3. The increased amount of carbon dioxide and other gases that humans have emitted in the last 100 years, which contribute to global warming.
  4. The ozone layer, which allows heat to pass through to the Earth, but not to escape.

• Question 4
  By how much has sea level risen in the last century?
  
  1. 0 - 5 cm
  2. 10 -15 cm
  3. 15 - 20 cm
  4. 25 - 35 cm

• Question 5
  What is the Earth's average temperature?
  
  1. 11 degrees Celsius
  2. 15 degrees Celsius
  3. 19 degrees Celsius
  4. 22 degrees Celsius

• Question 6
  Carbon dioxide accounts for what percentage of greenhouse gas emissions:
  
  1. 25 %
  2. 34 %
  3. 63 %
  4. 78 %

• Question 7
  In the United States, average greenhouse gas emissions per person in 1995 were:
  
  1. 2 tonnes
  2. 3.5 tonnes
  3. 5.2 tonnes
  4. 6.6 tonnes

• Question 8
  In Switzerland, average greenhouse gas emissions per person in 1995 were:
  
  1. 2 tonnes
  2. 3.5 tonnes
  3. 5.2 tonnes
  4. 6.6 tonnes

• Question 9
  The Kyoto protocol commits countries in the developed world to cut greenhouse emissions by 2012 by:
  
  1. 5% below 1990 levels
  2. 25% below 1990 levels
  3. 30% below 1990 levels
  4. 60% below 1990 levels

• Question 10
  Scientists say if we continue to emit greenhouse gases at current rates, over the next 80 years there is likely to be:
  
  1. A substantial dieback of tropical forests, especially in South America and southern Africa.
  2. Increased cereal yields in North America, China and Argentina.
  3. Less water in rivers in Australia, India, Europe and the Middle East
  4. All of above
