The Impact of Climate Change Communications in Providing a Sustainable Future

The acceleration of climate change has made the need for effective communication about its dangers more critical than ever. Global temperatures have been rising at a steady rate of 0.11° Fahrenheit per decade since 1850, with 2023 standing out as one of the hottest years ever recorded. This warming has fueled an alarming increase in natural disasters—raging wildfires, prolonged droughts, devastating floods—that has displaced millions and destroyed livelihoods. The impact of these climate events extend beyond the environment, plunging economies into instability, particularly in vulnerable regions like Africa and Southeast Asia, where adaptive capacity is lower.

Despite decades of scientific evidence and growing public awareness, meaningful climate action has lagged behind. While global conversations about climate change have intensified, they often fail to inspire concrete action. A few studies such as the Pew Research Center study, reveal that although people increasingly recognize the climate crisis, there’s a disconnect between understanding the problem and its urgency and acting on it. Factors like overwhelming information, uncertainty about its urgency, unclear messaging, perceived inaction bias, and a sense of helplessness can leave individuals feeling unsure about how to contribute effectively. For climate communication to be truly impactful, it must shift from simply informing to empowering people to make real changes—individually and collectively. The challenge now lies in transforming this awareness into coordinated efforts that drive the large-scale actions needed to combat climate change.

Despite growing concerns about climate change, behavioural science explains why many people still fail to act. One significant factor is psychological distance—the tendency for people to see climate change as a distant issue, either geographically or in time. When the climate crisis is framed as something that will only impact future generations or far-off places, it’s harder for individuals to feel an urgent need to take action. However, when impacts are communicated as immediate and local, people are more likely to change their behaviour. A 2022 study found that framing climate risks as present and relevant to everyday life increased people’s willingness to engage in pro-environmental actions.

Additionally, optimism bias plays a key role. Many individuals believe that climate change will affect others more than themselves. While they recognize the seriousness of the issue, they often assume the worst effects will occur far away, or only to future generations. This bias reduces the likelihood of people taking personal steps to mitigate climate risks. Effective communication needs to counter this by making the impacts of climate change personal and immediate—showing how individuals and communities are affected right now.

Another major hindrance to climate action in spite of awareness is pluralistic ignorance. Many individuals underestimate the willingness of others to act, leading to this phenomenon. While there is significant global support for climate action, people often assume that their peers are less concerned or less willing to make changes, which dampens collective momentum. Correcting this misperception is crucial in fostering widespread, coordinated climate efforts. When people believe their peers support climate initiatives, they are more likely to follow suit. However, the perception gap—where individuals underestimate others’ willingness to act—creates a barrier to collective action.

One of the most effective ways to communicate the urgency of climate change is by framing it as a public health issue. Climate-related changes, such as extreme heat, rising sea levels, and shifting weather patterns, are directly affecting global health. According to research, climate change exacerbates air pollution, spreads vector-borne diseases, and worsens food and water insecurity. As suggested by the Harvard School Of Public Health, highlighting these health impacts—like increased respiratory diseases from air pollution— in climate communication, people can be motivated to take immediate action, making the crisis more tangible and personally relevant. Other strategies include:

1. Emotional Appeal: Shaping Perceptions and Actions
   Data alone rarely compels people to act. This is where the emotional aspect of climate communication becomes critical. A study published in Research Gate suggests that messages with emotional resonance are far more likely to result in behaviour change than those based solely on facts. For example, stories of individual families displaced by wildfires in California or Australia evoke a sense of empathy, connecting people emotionally to the crisis.
   Consider the wildfires that ravaged parts of Greece and Canada in 2023 or the flood that destroyed cities in Maiduguri. These disasters not only destroyed ecosystems but also devastated local communities. Images and narratives of families losing their homes and livelihoods were more impactful than raw data on how many acres of land burned. Such emotional storytelling is key to making abstract, global phenomena tangible for the public. The climate crisis becomes more real when it’s presented as a human story, not just a scientific or statistical problem.
2. Focusing on Co-Benefits: Health as Drivers of Action
   Beyond addressing psychological barriers, another key to effective climate communication is focusing on co-benefits that resonate with people’s immediate needs and values. An article from George Mason University suggests that emphasizing the health benefits of climate action—like cleaner air reducing respiratory diseases—has a stronger effect on behaviour than simply talking about lowering carbon emissions. This approach has worked in cities like Copenhagen and Stockholm, where campaigns framed climate action around improving public health and air quality, rather than solely focusing on reducing emissions. By connecting climate action to everyday benefits, communicators can more effectively inspire both individual and collective behaviour changes.
3. The Power of Local Narratives
   Despite global efforts, climate communication is most effective when it amplifies local voices. Indigenous communities, for instance, have centuries of experience adapting to changing environments, but their stories are often overlooked in the global narrative. In Nigeria, youth-led environmental movements are tackling pollution and waste management, using social media to raise awareness. Similar to this, effective communication corrects this imbalance by making information relevant to local contexts. It is important that climate messages must consider cultural, social, and economic contexts to resonate globally. For instance, while messaging in Europe may focus on reducing car use, in regions like Lagos, where public transport systems are weak, that message fails to connect. Tailoring communication to different audiences is key to closing the gap between awareness and action.
4. A Sustainable Future Requires Better Communication
   At its core, climate communication must bridge the gap between awareness and action. As research in human behaviour suggests, the way we frame messages significantly impacts how people respond. Emotional appeals, localized narratives, and a focus on co-benefits like health and community well-being are all critical strategies for motivating people to act.
   The statistics may be sobering—2023 recorded some of the hottest temperatures and climate disasters in modern history—but how we communicate these facts will dictate whether they inspire change. Using behavioural science, human-centred stories, and global-local dynamics can help us craft communications that not only inform but also empower. The future of the planet depends on getting this right.
