Glоbаl cоrаl reefs suppоrt а high amount of biodiversity and are experiencing widespread bleaching due to rising temperatures and ocean acidification. As corals die, the reef ecosystems lose their capacity to take up and store carbon, reducing a key natural sink for atmospheric CO₂. 1) Explain why this scenario illustrates a positive feedback in the climate system. 2) Next discuss some ecological and societal consequences of the degradation of coral reefs, and suggest potential strategies for mitigating (i.e. reducing) these negative effects. Rubric Understanding of positive feedback (5 points): Provides a clear explanation of how this represents a positive feedback. Discussion of ecological consequences (4 points): Thoughtful discussion of ecological consequences. Discussion of societal consequences (3 points): Thoughtful examples of impacts on human communities. Mitigation strategies (4 points): Thoughtful, realistic suggestions.
