When researchers at the University of Nottingham's School of Psychology asked 160 people to brainstorm ways to live more sustainably, they discovered something that upends the standard playbook of climate communication: hope works better than fear at sparking the creative solutions we need.
The finding matters because climate action often feels abstract and overwhelming. When campaigns rely on fear, guilt, and alarm—the emotional tools that dominate much climate messaging—they may trigger an initial jolt of concern but often fail to sustain the kind of problem-solving creativity required for meaningful change. Professor Alexa Spence and her team wanted to test whether positive emotions might work differently, potentially opening wider doors to longer-lasting behavior change.
The researchers developed what they call a "climate creativity" measure, a novel way to assess how creative people become when thinking about sustainability. In their first study with 160 participants, they asked people to generate ideas for making their lives more sustainable and tested their general creative abilities through word association and environmental problem-solving tasks. The results hinted at something promising: positive emotional states seemed to fuel creative thinking in ways that negative emotions did not.
To test this more directly, the team ran a second experiment with 334 participants. They created two videos with deliberately contrasting emotional messaging. The hope video took an optimistic stance on climate change, highlighting potential solutions with positive language, cheerful tone, and uplifting background music. The fear video did the opposite—it expressed doubts about whether solutions would work, used alarming language, featured downbeat music, and darkened the imagery. After watching one of the videos, participants completed general creativity measures and the climate creativity task.
The results were clear: those who watched the hope video showed significantly higher levels of creativity, especially when tackling climate-specific problems. This is the first study of its kind to demonstrate that hope-based communication directly increases what the researchers call "climate creativity"—the ability to generate novel, actionable ideas for personal and collective sustainability. As Spence explained, "The results of the study indicate that inspiring hope in climate change is related to increased levels of creativity, and specifically climate creativity."
What makes this finding particularly valuable is the theory behind it. Positive emotions like hope don't just make people feel better—they seem to broaden thinking and encourage the kind of open, exploratory mindset that creativity requires. By contrast, fear and alarm tend to narrow focus, triggering defensive reactions rather than generative ones. For climate action, where people often face real barriers and genuine complexity, the ability to think creatively around solutions could be transformative.
The implications ripple outward. Climate campaigns promoting behaviors that are difficult—switching to renewable energy, redesigning consumption habits, pushing for systemic change—may benefit significantly from emphasizing what's possible rather than what's at stake. Hope, in this framing, isn't naive optimism divorced from reality. It's a practical tool for unlocking the problem-solving capacity we urgently need. By shifting how we communicate about climate change, we might help people not just feel motivated, but think their way toward meaningful action.
