Volcanoes have a complex relationship with sustainability and climate: they contributed to the formation of Earth’s atmosphere, can have short-term effects on local climate and world climate, and have been used as a scapegoat for man-made climate change. A better understanding of volcanoes and their relation to climate provides students with a more nuanced view of their environment, specifically climate change. By interesting students in environmental science, one hopes that their fascination leads to greater investment in the sustainability of their local environments.
