Knowledge Issue: What can predictions about our planet tell us about the future?

This knowledge issue relates to the topic of global warming, as there have been many theories present about how it will affect our planet in the future. It is predicted that temperatures will rise from 3.2 Fahrenheit to 7.2 Fahrenheit by the end of this century and it has been predicted by scientists that sea levels will rise in the range of 7-22 inches by 2100. From these predictions, we can deduce some conclusion about what will happen to Earth in the future. For example, higher temperatures could melt ice caps, cause flooding and crop failure and rising sea levels could cover landmasses and destroy countries and islands.

Perspectives on Global Warming:


 * The 1st perspective: ‘Nature Benign’ –
 * Quote: “nature is very robust and responds well to man-made disturbances; always returning to its natural state.”
 * The 2nd perspective: ‘Nature Ephemeral’ –
 * Quote: “nature is fragile and doesn’t respond well to manmade disturbances, when disturbance is caused nature will not automatically return to its original state”
 * The 3rd perspective: ‘Nature Perverse/Tolerant’ –
 * Quote: “nature can tolerate disturbances up to a certain degree. If disturbance is small nature will return to equilibrium, larger disturbances pose of threat for nature functioning.”
 * The 4th perspective: ‘Nature capricious’ –
 * Quote: “nature is random and unpredictable and we will never know exactly how it will respond to disturbances.”
