Public Perceptions of Climate Change and Its Health Impacts: Taking Account of People's Exposure to Floods and Air Pollution.

Climate change-related exposures such as flooding and ambient air pollution place people's health at risk. A representative UK survey of adults investigated associations between reported flooding and air pollution (in the participants' local area, by the participant personally, and/or by family and close friends) and climate change concerns (CCC) and perceptions of its health impacts (PIH). In regression analyses controlling for socio-demographic factors and health status, exposure was associated with greater CCC and more negative PIH. Compared to those with low CCC, participants who reported local-area exposure were significantly more likely to be fairly (OR 2.07, 95%CI 1.26, 3.40) or very concerned (OR 3.40, 95%CI 2.02, 5.71). Odds of greater CCC were higher for those reporting personal and/or family exposure ('fairly concerned': OR 2.83, 95%CI 1.20, 6.66; 'very concerned': OR 4.11, 95%CI 1.69, 10.05) and for those reporting both local and personal/family exposure ('fairly concerned': OR 3.35, 95%CI 1.99, 5.63; 'very concerned': OR 6.17, 95%CI 3.61, 10.55). For PIH, local exposure significantly increased the odds of perceiving impacts as 'more bad than good' (1.86, 95%CI 1.22, 2.82) or 'entirely bad' (OR 1.88; 95%CI 1.13, 3.13). Our study suggests that public awareness of climate-related exposures in their local area, together with personal exposures and those of significant others, are associated with heightened concern about climate change and its health impacts.
