Using survey methodology, students' beliefs, and willingness to act, about 16 specific actions related to global warming are compared across the primary secondary interface. More primary students believed in the effectiveness of most actions to reduce global warming and were willing to take those actions. In general there was a disparity between students' beliefs and their actions and explanations are proffered for these differences. Characteristics that distinguish primary from secondary schooling are proposed for the variations across the interface and these have implications for practice.
