DEFINING ONE OR MORE RELEVANT KNOWLEDGE ISSUES: How effectively can Reason as a Way of Knowing (in particular cold, hard logic) tackle a complex scientific issue like global warming? 4.

CLIMATE MODELS WITH MULTIPLE VARIABLES Our most sophisticated models are necessarily simplifications; no matter how sophisticated: What is being included what is left out ? What assumptions are made? What is the predictive power? Harder than predicting avalanches but easier than predicting earthquakes 7.

CONCLUSION THE PRECAUTIONARY PRINCIPLE ROOTED IN A LOGIC TRUTH TABLE IB BIOLOGY CORE 5.2.4 Outline the precautionary principle. The precautionary principle holds that, if the effects of a human-induced change would be very large, perhaps catastrophic, those responsible for the change must prove that it will not do harm before proceeding. This is the reverse of the normal situation, where those who are concerned about the change would have to prove that it will do harm in order to prevent such changes going ahead If the possible consequences of rapid global warming are devastating enough, preventive measures are justified even if it is far from certain that rapid global warming will result from current human activities 12.
