One Day When We Were Young: Nostalgia Brings Climate Change Temporally Closer

The perceived temporal distance of climate change impacts has been considered a long-standing barrier to climate engagement. Because nostalgia has distinct cognitive properties related to temporal thinking, three experimental studies are conducted to investigate nostalgia's potential for shortening temporal distance. Study 1 shows that nostalgia increases climate engagement by reducing temporal distance. Study 2 further identifies vivid imagery as a mechanism for the nostalgia effects across US and Chinese samples. Study 3 shows that nostalgic public service announcements increase climate engagement more than non-nostalgic ones. This study provides strong evidence that evoking nostalgia can be a useful climate change communication strategy.
