Global warming has become one of the most important climatic problems across the world since it was first noticed in the 19th century when scientists first started to measure the annual mean of the global temperature and calculate the carbon dioxide level in the atmosphere. As global warming leads to many other environmental problems, there have been numerous studies and research carried out to slow down and stop it (Jacobson, 2012; Le Treut, 2007). Shortly after the realization of the serious rise in the global temperature and the noticeable damage in the polar ice, more attention was given to the issue. Articles until the 1990s were mostly statistical and medical reports, warnings, and regression studies about the potential future threats of global warming. For instance, Broecker (1975) reported that the world was at an irreversible brink of a global warming crisis. Then, to raise social awareness on this major problem, subjects such as sustainable development, protecting the environment, climate change, and global warming began to be included in the curricula around the world (Özcan and Demirel, 2019). With the involvement of such subjects in education, several scientific studies have been carried out for analyzing the learning and teaching processes.
