Being intrinsically associated with death-related themes (e.g. decay, destruction, lack of control, chaos), communicating climate change risks may elicit thoughts in an audience about their own mortality - potentially invoking terror management responses. This study examined individual differences in death-thought accessibility (DTA) amongst Australian university students (N=241) after exposure to information about climate change impacts, to predict climate change risk perceptions. It was posited that information about the impacts of climate change would lead to worldview defence (a terror management strategy) via increasing death-related thoughts. Although climate change salience did not invoke DTA, there was evidence that choosing not to complete word-fragments in a death-related manner reflected a high death-defensive response, rather than low-DTA. Compared with a control condition, climate change salience participants' risk perceptions shifted liberally. The function of death-related thoughts depended on the individual's climate change beliefs. Climate-deniers with high-DTA in the climate change salience condition showed greater risk perceptions compared to those with high-DTA in the control condition. Risk perceptions did not change as a function of DTA amongst climate-acceptors. A general implication was that climate change communications, may not produce counterproductive terror management outcomes as has been previously hypothesized. Rather they may motivate more realistic attitudes, such as perceiving climate change as high-risk, even amongst climate-deniers. From a policy perspective, to maximise acceptance, climate change information may benefit from being presented within frameworks that support individuals important personal worldviews.
