Climate Change Terminology: Public Understanding and Communication Challenges
Key Climate Change Terms and Public Comprehension
Research shows that many people struggle to understand key climate change terms used by organizations like the IPCC. Terms such as "mitigation," "carbon neutral," and "unprecedented transition" are often seen as difficult, while "adaptation" and "abrupt change" are easier to grasp. However, even when people think they understand a term, they may not connect it clearly to climate change or may apply it incorrectly based on other contexts. Complex language and long sentences in official communications further hinder understanding. Recommendations include simplifying wording, making explicit links to climate change, and clearly describing underlying processes to improve public comprehension De Bruin2021Wege2024.
The Impact of Terminology on Public Attitudes and Actions
Studies testing different climate change terms—like "climate change," "global warming," "climate crisis," "climate emergency," and "climate justice"—find that familiar terms ("climate change" and "global warming") are rated as most familiar and concerning. Less familiar terms, such as "climate justice," generate less concern and urgency across political groups. Importantly, changing the terminology does not significantly increase perceived urgency or willingness to take climate action, such as supporting policies or changing personal behavior. This pattern holds true across diverse populations and cultures, suggesting that focusing on terminology alone is not an effective strategy for promoting climate action De Bruin2024Goldwert2024.
Variation and Evolution in Climate Change Language
The language of climate change is constantly evolving, with new terms (neologisms) like "ecoanxiety," "climavore," and "energy transition" reflecting society’s growing awareness and emotional response to the issue. However, frequent variation in terms and concepts, especially in translation or across different languages, can lead to misunderstandings and inaccuracies. This variation can hinder effective communication and even exacerbate confusion or mistrust among the public. Clear, consistent terminology is essential, especially in international and multilingual contexts Idrissi2024Cabezas-García2022.
Shifts in Popular Usage and Sentiment
Analysis of online discussions over the past 16 years shows that "climate change" has overtaken "global warming" in popularity since 2013. The term "climate change" is associated with more negative sentiment and higher subjectivity in online conversations. Despite the growing number of online posts, the proportion of climate-related discussions is declining, indicating waning public engagement. The choice of terminology influences not just understanding, but also the tone and emotional response in public discourse Fariello2025Gammage2016.
The Need for Clear Definitions and Consistency
There is a lack of shared definitions for many transformation-related terms in climate change research and policy, which creates challenges for both scholarship and evidence-based policymaking. Proposals have been made to use umbrella terms like "transformational climate change mitigation" to unify varied concepts and support more effective communication and action .
Conclusion
Overall, research highlights that while climate change terminology is evolving and reflects society’s engagement with the issue, complex or unfamiliar terms can hinder understanding and action. Familiar, clearly defined, and consistently used terms are more effective for public communication. However, simply changing terminology is unlikely to drive greater climate action; instead, communicators should focus on clarity, context, and explicit links to climate change processes to improve public understanding and engagement De Bruin2021De Bruin2024Wege2024+4 MORE.
