Awareness of everyday effects of climate change: The climate change perceptual awareness scale (CCPAS)

Climate change is intrinsically complex and demands a certain degree of abstraction. However, different individuals report a wide range and degree of tangible and sensory experiences of climate change. As perceptual and sensory awareness of climate change has important consequences for the promotion of sustainable behaviors, pro-climate policies, and clinical interventions for climate-related disorders such as climate anxiety, new specific tools are required: herein we detail the development of a psychometric measure of perceptual awareness of climate change, as well as provide evidence for its discriminant, convergent, and predictive validity for sustainable behaviors. The administration of this scale on a representative sample of the UK population (Study 1) yielded a 4-factor structure, with items measuring perception of temperature changes and those measuring perception of humidity changes loading on separate factors, and two additional factors identifying the awareness of own feelings and perception of media attention on climate change. A second administration (Study 2) to an independent sample gathered from the Italian population supports the reliability of this factorial structure. As the rising field of climate neuroscience starts to investigate the determinants of perceptions of climate change, this novel scale will allow assessing the perceptual features affecting awareness of climate change.
