The goal is not awareness alone: it is to help people make informed decisions and take protective action. The World Health Organization (WHO) defines risk communication as an exchange of information, advice, and opinions between experts or officials and people facing a threat; the United Nations (UN) climate communication guidance emphasizes educating and mobilizing audiences.
What is climate risk communication?
Climate risk communication shares relevant information about climate-related hazards, their likelihood or severity when that is known, who or what may be exposed, and how vulnerability and practical choices shape the consequences. It should help people understand a decision—not simply give them more facts.

A useful message connects the hazard to the audience’s circumstances, makes the limits of available knowledge clear, and identifies a realistic next step. A general WHO definition offers a transferable framework for this work; it is not climate-forecast guidance. The UN’s climate communication guidance recommends authoritative science, trusted messengers, relatable stories, and solution-focused framing.

Trust comes from conduct, not a reassuring tone by itself. Be accurate, timely, transparent about how recommendations were reached, and willing to listen to people affected by the risk. WHO says trust between experts, authorities, and affected people is central to effective risk communication, alongside credibility, empathy, and understanding the audience. Its risk communication Q&A puts the uncertainty point plainly: “Explaining honestly what is known and admitting what is uncertain is essential.”
#1 Best Overall
- Share what supports a conclusion or recommendation, and distinguish evidence from judgment.
- Make updates promptly when information or advice changes; explain what changed and why.
- Invite questions and concerns, and show how they affect the conversation or response.
- Use a messenger the intended audience considers credible, rather than assuming official status alone will persuade.
There is no universal numerical guarantee that a particular tone or technique will create trust. The practical test is whether people understand the message, see it as credible, and have a meaningful opportunity to respond.
How do you communicate uncertainty without losing trust?
State uncertainty as part of the information people need to make a decision. WHO advises explaining the limits of knowledge and identifying interim recommendations as subject to change as evidence develops. A clear explanation can follow this sequence:
- What is known: describe the evidence or current assessment that is relevant to the decision.
- What is not known: name the unresolved question or range of possible outcomes without implying certainty that is not there.
- Why it matters: explain how that uncertainty affects the choice people face.
- What is being done: say how authorities or experts are working to learn more, if that is known.
- When advice may change: state what new information or conditions would prompt a review, where possible.
If advice is provisional, label it clearly rather than presenting it as final. WHO/Europe’s emergency communication guidance similarly recommends saying what is known, what is not known, and what is being done to learn more. That is a general emergency-communication principle applied here; it is not climate-specific forecast guidance.
What makes climate advice actionable?
Advice is actionable when it names a concrete choice, gives a reason that matters to the audience, and makes the first step clear. WHO’s planning framework asks communicators to identify the behavior or action to encourage or discourage and whether the audience understands both the risk and the recommended response. It also highlights confidence, community endorsement, and whether people believe the benefits outweigh the costs.
Rank #3
- Name the action: avoid vague prompts such as “be prepared” when a more specific step is appropriate.
- Explain the reason: connect the action to the risk and the decision it helps address.
- Check feasibility: consider whether people have the time, money, information, access, and support to act.
- Point to help: include a reliable place to get current local guidance or assistance when one is available.
- Use plain language: put the important point first and do not bury it in technical detail.
WHO’s plain-language guidance says, “People are more likely to trust and act on information they understand.” The UN climate guidance also recommends connecting climate issues with local or personal experience and presenting solutions in ways that engage rather than overwhelm. Advice should be tailored to the hazard, jurisdiction, and current local guidance; a general communication framework cannot replace a local risk assessment.
Should everyone receive the same climate message?
No. People differ in their beliefs, values, risk perceptions, information sources, and trusted messengers. Yale’s Program on Climate Change Communication describes distinct audiences in the United States and advises communicators to learn about people’s knowledge, misunderstandings, values, emotions, and sources of information. Its U.S. audience overview is useful for understanding that variation, but its audience categories are not a global taxonomy and should not be used to infer what an individual believes.
Use audience research as a starting hypothesis, then listen to the actual community. Adapt for the audience’s decision, language, locality, communication channels, and access to resources. Yale’s message research describes testing combinations of message, messenger, and format, and assessing outcomes such as beliefs, attitudes, policy support, and behavior. Testing can help identify what communicates well; it does not guarantee behavior change.
Yale’s 2025 U.S. audience segmentation reported that the Alarmed share rose from 11% in 2015 to 25% in 2025, the Cautious share fell from 24% to 17%, and the combined Alarmed or Concerned share rose from 42% to 52%. These are figures about Yale’s U.S. audience segmentation over time, not global estimates or proof that a particular communication intervention caused the changes.

How should communicators compare approaches?
Evaluate a communication approach against the decision it is meant to support. A message that is persuasive but inaccurate is not effective; neither is accurate advice that the audience cannot understand or realistically follow.
| What to assess | Questions to ask |
|---|---|
| Accuracy and uncertainty | Does the message represent the evidence faithfully and disclose important limits? |
| Trust and messenger fit | Does the audience regard the messenger as credible and attentive? |
| Comprehension | Can people explain the risk and advice in their own words? |
| Actionability | Is there a clear next step, and can the intended audience realistically take it? |
| Local relevance and equity | Does the message account for local exposure, vulnerability, language, and access to support? |
| Channel and format | Does it work in the channels and formats the audience uses? |
For U.S. resilience practice, the U.S. Climate Resilience Toolkit lists NOAA-linked training and community-engagement resources. The American Psychological Association’s climate change resources also lists the Uncertainty Handbook: A Practical Guide for Climate Change Communicators as further reading. These resources can support planning; they do not substitute for local listening or prove that a message will produce a particular outcome.
