A frequent suggestion to increase individuals' willingness to take action on climate change and to support relevant policies is to highlight its proximal consequences, that is, consequences that are close in space and time. However, previous studies that have tested this proximising approach have not revealed the expected positive effects on individual action and support for addressing climate change. We present three lines of psychological reasoning that provide compelling arguments as to why highlighting proximal impacts of climate change might not be as effective a way to increase individual mitigation and adaptation efforts as is often assumed. Our contextualisation of the proximising approach within established psychological research suggests that, depending on the particular theoretical perspective one takes to this issue, and on specific individual characteristics suggested by these perspectives, proximising can bring about the intended positive effects, can have no (visible) effect, or can even backfire. Thus, the effects of proximising are much more complex than is commonly assumed. Revealing this complexity contributes to a refined theoretical understanding of the role psychological distance plays in the context of climate change and opens up further avenues for future research and for interventions.

This perception of climate change as a distant threat is problematic because it implies little personal relevance. Low levels of personal relevance in turn are problematic because individuals' perception of being personally at risk can be an important motivation to take action against the source of that risk 9-14 .Consistent with this analysis, it has repeatedly been suggested that highlighting the proximal consequences of climate change could be an important part of strategies to engage and mobilize publics around this issue 3,[15][16][17][18][19][20] . Although the assumed psychological mechanism of proximising is often not verbalised (see also ref. 21 , where the term is used to describe a discursive strategy in which the speaker presents physically and temporally distant events as close and directly relevant to the addressee), the rationale behind proximising climate change seems to be that this approach (a) decreases the psychological distance between the issue and individuals who could or should act 17,22 and, (b) makes the consequences of climate change easier to visualise 4,23 and more personally relevant 24,25 . Moreover, proximising climate change is believed to increase (emotional) concern 16,22,26,27 and the feeling o...
