What is the Green house effect?
What causes it?
How do we know?
Can we justify action if everyone is not convinced?
Write and essay and let me know!
What you should include:
 Outline the Precautionary Principle,
 Evaluate the PP as a justification for strong action in response to the threats posed by the
enhanced greenhouse effect.
 Analyze the changes in atmospheric carbon dioxide, and show how those changes are
linked to enhanced Greenhouse effect. Use Historical Data from either Hawaii or
Tasmania.
 Use the consequences of a global rise in temperature on arctic ecosystems in your
evaluation.
