What most people don't realize is that the direct heating from greenhouse gases only describes part of the story. The heating directly caused by increasing greenhouse gases can lead to a cascade of other changes to the Earth System called climate feedbacks. 1. You work for an international freight company with a fleet of large container vessels. You have a meeting with the COO of the company who wants to learn more about climate feedbacks. How would you explain what positive and negative feedback mechanisms are? 2. How would you explain three of the feedback mechanisms we discussed in class to your COO. Which of the feedbacks we discussed in class should your COO be most concerned about though not because of the impacts on temperature?
