Question: Consider the following feedback systems: i: increased carbon dioxide leads to warming, which leads to more evaporation, leading to more drought, leading to more wildfires, leading to the release of carbon dioxide stored in plants. ii: decreased carbon dioxide leads to cooling, which leads to less evaporation, leading to less drought, leading to less wildfires, leading to more carbon dioxide stored in plants. Which of the following is correct. a. i is a positive feedback, ii is a negative feedback b. Both i and ii are negative feedbacks c. Both i and ii are positive feedbacks d. ii is a positive feedback, i is a negative feedback
