The global climate crisis has arrived. Globally, climate events are now accelerating at paceheatwaves, floods and droughts are becoming more severe, from North America to Africa to Asia, and everywhere in between. The effects are now clear to see. Here in Ireland, we are not immune to global heating. We cannot afford to ignore the very real challenges the crisis will bring: from the wholesale decarbonising of our economy towards renewable energy systems, to restoring biodiversity, implementing a just transition and building a more equitable society and, most importantly of all, creating a sustainable world for future generations. With this in mind, and as per TUI policy set by Congress, the TUI Climate Change Committee has worked with University College Cork to devise a training course for TUI members. This introductory course designed specifically for second level school teachers will explore the key issues and questions, and the solutions, now arising as a consequence of our warming world-for example, what will responsible consumption look like, how do we understand eco-anxiety, what is the importance of local and global citizenship, and accelerating the shift to renewable energies such as wind and solar away from fossil fuels, amongst others subjects.'
