This lecture introduces the analysis framework for evaluating the impacts of the life cycle, focusing on the cause-effect chain of climate change, environmental interventions, and the relationship between problem and damage levels. It also covers the categories of impact related to climate change, emphasizing the importance of understanding the environmental implications of various elements. The lecture further discusses how flux elements can be linked to impact categories at different levels, highlighting the interconnectedness of environmental issues. Additionally, it explores the concept of uncertainty in interpreting environmental data and the advantages of the problem-damage modeling framework, emphasizing coherence and environmental relevance in decision-making.
