3.1 Identified lessons and their categories
Analysis of the identified lessons revealed the most pressing issues regarding climate change and COVID-19. Visualizing the main keywords contained in these lessons (Fig. 3) displays that subjects such as climate trajectories, global politics, decision-making, timely action, and public attention show the highest frequencies. This indicates the relative importance of these issues. This graphical representation of keywords allows our target group to quickly identify the most common themes underlined in the collected lessons. Our final list of 49 lessons belongs to nine broad thematic areas, as described above. Lessons belonging to categories such as “perception and behaviour”, “policy and governance”, “research and education”, and “scoio-economic inequality” show a relatively higher number of lessons than the other themes (Fig. 4).
