Climate Change Health Communication and its Association with Awareness and Behaviors in South Korea

Objective: This study investigates the relationship between public communication experiences (information-seeking and climate communication) and both awareness of health risks from climate change and actual adaptive behaviors (pro-environmental and health-focused) among adults in South Korea. It aims to assess whether current communication strategies effectively translate awareness into action.

Scope & Methodology: A nationally representative online survey was conducted with 2,000 Korean adults aged 19–64 in September 2024. The study employed a cross-sectional design to measure:

• Communication Experiences: Frequency of seeking information on climate-health impacts and engaging in climate-related activities (e.g., discussions, activism).
• Outcomes: Perceived susceptibility to health risks, pro-environmental behavior, and health adaptation behavior.
• Key Mediators: Climate self-efficacy and perceived social norms.

Analyses included descriptive statistics, group comparisons (t-tests, ANOVA), and regression modeling to identify associations.

Key Findings:

1. Communication Does Not Enhance Risk Awareness: Contrary to expectations, increased experience with information-seeking and climate communication was associated with a lower perceived likelihood of personal health risks (death and illness) from climate change. This suggests current communication fails to build accurate personal risk perception.
2. Communication Promotes Pro-Environmental Behavior: Both information-seeking and climate communication experiences were positively associated with increased engagement in pro-environmental behaviors (e.g., energy saving, sustainable consumption).
3. Communication Promotes Health Adaptation Behavior: Similarly, more frequent communication experiences were linked to greater adoption of specific health-protective behaviors in response to climate change (e.g., following heatwave guidelines).
4. Critical Role of Self-Efficacy and Social Norms: The strongest predictor of health risk perception was not communication, but an individual’s climate self-efficacy (belief in one’s ability to make a difference). Both self-efficacy and perceived social norms (belief that others are acting) were strongly and positively associated with all adaptive behaviors.
5. Demographic Variations: Higher susceptibility to health risks was found among women, older adults, those with a spouse, and politically progressive individuals. Adaptive behaviors were more common among those with children, living in disaster-prone areas, and with higher baseline awareness.

Conclusions & Implications:

• Ineffective Risk Communication: Current climate-health communication in South Korea is successful in motivating action but fails to improve accurate personal risk awareness. This disconnect may threaten the sustainability of behavioral changes.
• Need for Strategic Reframing: Effective communication must move beyond simply conveying risks. It should:
  • Emphasize Solutions and Benefits: Frame messages around the health and economic co-benefits of climate action, rather than solely focusing on threats.
  • Boost Self-Efficacy: Provide clear, actionable steps that empower individuals and demonstrate collective impact.
  • Leverage Social Norms: Highlight community and societal actions to reinforce positive behaviors.
  • Be Tailored and Credible: Develop targeted messages for different stakeholders (policymakers, healthcare workers, public) and ensure they are backed by visible, tangible government action.

Significance: This study highlights a critical gap in South Korea’s public health communication strategy for climate adaptation. It provides evidence that motivating behavior requires a nuanced approach that builds empowerment and social solidarity, not just risk awareness. The findings call for a systematic overhaul of communication strategies to foster a well-informed, efficacious, and proactive public capable of sustaining health-protective behaviors in the face of the climate crisis.

It Only Works If You Believe In It: How Climate Change Awareness Affects The Effectiveness Of Energy Initiatives

Objective: This study empirically examines the critical role of public climate change awareness in determining the success of government energy initiatives aimed at promoting investments in renewable, solar, and wind energy.

Key Findings:

1. Awareness is a Critical Moderator: Climate change awareness significantly enhances the effectiveness of both market-based energy policies (e.g., feed-in tariffs, tax incentives) and energy legislation. The positive impact of these initiatives grows as public awareness increases.
2. Threshold Effects Exist: For many initiatives, there is a critical awareness threshold below which policies are ineffective or even counterproductive.

• Market-based policies for renewable and solar energy only become effective when climate change awareness is sufficiently high.
• Solar energy legislation shows a similar pattern: it can negatively impact investment at very low awareness levels but becomes positive at higher levels.

3. Variation by Energy Type:

• The results are strongest and most consistent for solar energy initiatives.
• Findings for wind energy are less clear, likely due to social opposition related to land use and visual impact, which can persist even among environmentally aware groups.

4. Country-Specific Effectiveness: As of 2022, only a subset of (mostly advanced) economies had awareness levels high enough to ensure the effectiveness of renewable energy policies (e.g., Italy, France, Germany, Switzerland, Israel). In many other countries, low awareness renders policies potentially ineffective.
5. Complementary Actions: The study finds a synergistic relationship between awareness and policy. Raising awareness makes existing policies more effective, and implementing policies in a high-awareness context yields greater results. Therefore, the most efficient strategy is to act on both dimensions simultaneously.

Policy Implications:

• Primacy of Awareness Building: Before or alongside implementing costly energy initiatives, governments must prioritize public education, communication, and dissemination of scientific findings on climate change to raise awareness above critical thresholds.
• Tailored Approaches: Policymakers must consider that the required awareness level and policy effectiveness vary by energy source (solar vs. wind) and policy type (market-based vs. legislative).
• International Coordination: Cross-country cooperation is essential to enhance global climate knowledge and awareness, as the current group of countries with sufficiently high awareness is small.
• Timing is Key: To avoid a vicious cycle of low awareness and policy failure, the timing of policy rollout should be carefully aligned with efforts to boost public understanding and concern.

Methodology:

• Data: Panel dataset of 53 countries from 2004 to 2022.
• Key Variables:
  • Dependent: Investments proxied by installed electricity capacity for renewables, solar, and wind.
  • Independent: Market-based policy indices, counts of energy legislation, and an interaction term with climate change awareness.
  • Awareness Proxy: Google Trends Search Volume Index (SVI) for the topic “climate change.”
• Model: Dynamic panel model estimated using a two-step system GMM estimator to address endogeneity and reverse causality.

Conclusion:

The transition to sustainable energy is not just a matter of designing the right policies or laws. Their success is contingent on public belief and concern. Climate change awareness is not merely a complementary factor but a fundamental precondition for the effectiveness of energy initiatives. Policymakers must, therefore, integrate strategic awareness-building campaigns into the core of their energy transition strategies.

Actionable Information And Climate Change Awareness Drive Consumer Selection Of Environmentally Beneficial Garden Plants

Objective: This study investigates how the presentation of information influences domestic gardeners’ plant choices, specifically their willingness to select plants with traits beneficial for mitigating urban environmental issues like flooding and air pollution. It also examines the role of climate change awareness in driving pro-environmental gardening behavior.

Key Findings:

1. “Action-Related Information” Drives Change: Providing gardeners with specific, actionable information about plant traits (e.g., hairy leaves capture pollution, “thirsty” plants mitigate flooding) significantly altered plant preferences. Participants who received this information were more likely to choose environmentally beneficial plants and less likely to choose purely ornamental options, compared to those who received only general “system information” about climate problems.
2. Climate Change Concern is a Powerful Motivator: A participant’s level of concern about climate change was a strong and independent predictor of their willingness to choose environmentally beneficial plants in the future. This effect was consistent across both information groups, indicating that pre-existing environmental concern is a key lever for promoting sustainable gardening practices.
3. Aesthetics Took a Back Seat: Contrary to much existing literature, aesthetic preference was not a significant driver for plant selection in this experimental context when environmental information was provided. This suggests that when actionable ecological benefits are clearly communicated, they can override or diminish the primacy of visual appeal.
4. Prior Gardening Knowledge Helps but is Incomplete: Participants with gardening experience or qualifications had greater baseline awareness of some ecosystem services (e.g., wildlife support). However, this knowledge did not extend to understanding the benefits of specific traits like high transpiration rates for flood mitigation, highlighting a key gap in current gardener education.
5. Effective Communication Model: The study supports a communication framework where combining “system information” (the problem) with “action-related information” (the solution) is most effective for changing behavior, aligning with the Theory of Planned Behavior.

Policy and Practice Implications:

• Promote Actionable Labelling: Industry and retailers (e.g., garden centers) should adopt clear labeling schemes (similar to the RHS “Plants for Pollinators” initiative) that highlight specific environmental benefits of plants (e.g., “flood-mitigating,” “air-purifying”).
• Leverage Climate Concern: Public outreach and educational campaigns should explicitly link sustainable gardening choices to climate change adaptation and mitigation, tapping into existing public concern as a primary motivator.
• Target Educational Gaps: Extension services and horticultural bodies should develop resources to educate gardeners about the functional traits of plants (like transpiration rates and leaf structures) and their role in solving local environmental problems.
• Collaborative Approach: A coordinated effort among policymakers, NGOs, plant producers, and retailers is needed to mainstream environmentally functional planting, transforming private gardens into a network of green infrastructure that can address city-scale challenges like urban heat and flooding.

Methodology:

• Design: Online experimental survey with 419 participants randomly assigned to one of two groups.
• Groups:
  • “System Information” Group (n=208): Received basic facts about climate change, flooding, and air quality.
  • “Action-Related Information” Group (n=211): Received condensed system information plus specific recommendations on plant traits that help mitigate flooding and pollution.

• Task: Participants selected preferred plants from six options (with known beneficial or neutral traits) before and after receiving the information.
• Analysis: Statistical models (ordinal regression) were used to analyze changes in knowledge, plant preferences, and the drivers behind those changes.

Conclusion:

To harness the significant potential of domestic gardens for urban climate adaptation, simply raising awareness of environmental problems is insufficient. Providing clear, actionable guidance on how to choose beneficial plants, combined with appealing to existing climate change concerns, is a highly effective strategy to shift gardening practices. This approach can empower private gardeners to make choices that collectively enhance urban ecosystem services.
