Welcome to the Geography Global Warming Forum. We hope this forum encourages critical thinking and questioning of global warming causes, effects and issues. Is global warming definitely caused by humans or is it a natural event that has happened before? Is Greenland warmer today than in the Middle Ages? Were sea levels higher in the past, if so, why? Do cows really contribute to global warming or do they simply act as carbon recyclers? Does Al Gore’s film ‘An Inconvenient Truth’ set out to scare using scientific untruths? Should we, or can we stop climate change?
