Climate change mitigation involves actions to limit long-term climate change by reducing human greenhouse gas emissions and increasing carbon sinks. Mitigation strategies discussed include avoided deforestation, reducing greenhouse gas emissions, switching to low-carbon energy sources, and using renewable energy. To engage learners with these concepts, the teacher will use De Bono's six thinking hats method, which encourages viewing issues from different perspectives using colored hats that represent facts, positives, emotions, critical thinking, solutions, and overall thinking. Learners will discuss mitigation strategies applying each hat's perspective.
