Anthropogenic climate change is impacting human survival through its impact upon water quality and availability. An urgent ethical imperative is thus raised for education policy makers and schools, particularly in the Australian and Asia Pacific regions, to adopt a curriculum to help students mitigate and adapt to the dire consequences caused by a warming planet. Through a blue transdisciplinary school curriculum, students will better understand and respond to the broader aspects of what is referred to as the hydrosocial cycle. A school move towards a blue curriculum requires educational policy to mandate an emphasis on the climate change effects upon the water cycle. An effective shift to a blue curriculum also requires that teachers’ ethical perspectives and sensitivities are sharpened through their tertiary education courses. This is needed so they develop confidence and pedagogy for teaching anthropogenic climate change generally, something still missing from Australian and other classrooms around the world, and, more specifically, for teaching the hydrosocial cycle. The Four Component Model of Ethical Decision Making is offered as a useful framework to guide teachers in examining their values and motivations when teaching potentially confronting topics such as the impacts of climate change upon the hydrosocial cycle.
