Abstract
Lightning has killed and injured many people in recent years in the Qinghai–Tibetan Plateau area of China when they were collecting a rare product used for medical applications. The fungus that grows on dead caterpillars at high altitudes in this region demands a high price when sold, so it attracts collectors that unfortunately become at risk from lightning during this process. A total of 12 lightning-related events during 2004–22 resulted in 29 deaths and 53 injuries. All cases occurred at high elevations in rugged terrain with no available lightning-safe structures or vehicles. The fungus collection occurred during the daytime hours in late spring and early summer, which is also when lightning is frequent. Maps of lightning for the cases and information gained from the Chinese-language reports are summarized. It is apparent that this is a unique high-risk, high-reward occupation that is similar in terms of exposure to other situations around the world that result in lightning deaths and injuries.
Significance Statement
Lightning deaths and injuries often occur when people push the limits of safety due to occupational or recreational demands. Most of these decisions are on short time scales such as while tending agricultural fields, working on roofs, running a competitive race, or walking home from school when a thunderstorm is approaching. In the scenario presented here, groups of people with few income alternatives spend weeks or months in mountainous regions where lightning is common, but safety is elusive. This situation is an unusual version of high lightning risk occurring while pursuing a high reward.

Abstract
With the global warming is becoming more and more serious, the global need for low-carbon economic transition is increasingly urgent. This study focuses on the time-frequency spillover effect of climate risk perception and energy market. By constructing transition risk perception and physical risk perception index and using time-frequency analysis, we quantifies the impact of climate risk perception on fossil energy and clean energy markets, and reveals the dynamic relationship between the two. The findings indicate that China’s sense of transition risk from climate change has increased since the Paris Climate Agreement, but the perception of physical risk has changed less. Moreover, the spillover effect between climate risk perception and energy markets is time-varying and increases rapidly in the face of climate or energy related uncertain events. The COVID-19 pandemic has resulted in a sharp drop in total spillover, and there is little near-information spillover between the energy markets and perceptions of climate danger. We also found that in the short term, energy market spillovers are net recipients of climate risk perception according to marginal spillover research. However, this connection changes to become a net transmitter from 2021. In the medium to long term, the perception of climate risk begins to function as a net transmitter of spillovers to energy markets.

Abstract
Flood early warning systems (FEWS) are essential in mitigating flood damage. To optimize their effectiveness, it is important to understand how people respond to warnings and prepare for flooding events. The key factors influencing social preparedness include (1) direct and (2) indirect experiences of floods and (3) trust in warnings. However, existing socio-hydrological models do not incorporate all these elements. To include these elements for social preparedness, we propose an idealized model that allows multiple regions to influence one another (i.e., regional interactions). We investigate the dynamics of social preparedness in a society composed of regions with varying infrastructure levels (e.g., levee heights) and explore strategies for developing a socially efficient FEWS. Numerical analyses reveal that in a society that has a region characterized by a low infrastructure level (i.e., a region with frequent floods), regional interactions lead to a pronounced cry wolf effect due to false alarms from other regions, diminishing social preparedness in the low-infrastructure region. These interactions also prevent a warning strategy that optimizes the natural science-based index (i.e., threat score) from maximizing social efficiency. Conversely, in a society that has a region characterized by a high infrastructure level (i.e., a region with infrequent floods), regional interactions enhance the efficiency of FEWS by improving social preparedness through indirect experiences with floods. These findings suggest that as regional heterogeneity increases, it becomes increasingly vital for forecasters to consider social aspects (e.g., people’s experiences, trust, and interactions) when establishing a socially efficient FEWS. The refined model will be valuable to forecasters in designing effective FEWS in real-world situations.

Abstract
This paper implements the “spatial first differences” (SFD) method to a Ricardian approach to analyze spatial differences in climate and evaluate their impact on farmland values in New Zealand. We use property valuation data from 1993 to 2018 across different agricultural land-uses. Ricardian analyses harness cross-sectional variation in climate and farmland values to estimate the effect of climate on agriculture. However, Ricardian studies are vulnerable to omitted variables varying slowly or not varying over time. The idea of the SFD approach is to apply spatial analogous of the “first-differences” estimator for longitudinal analyses to control for omitted variables that vary differently than climate variables among neighboring units. The results suggest that a warmer or drier climate is associated with higher farmland values in New Zealand. These findings may be mediated by productivity differences, costly physical improvements, and climate amenity values. Besides contributing novel insights by applying the Ricardian approach to New Zealand data and overcoming challenges of unobserved heterogeneity with the SFD method, we conclude that, for a better understanding of the welfare implications of climate change, it is crucial to differentiate between the effects of costly improvements and amenity values, apart from the pure climate productivity effect.

Abstract
To better understand individuals’ behaviour in the face of a natural disaster, and to evaluate the preventive information provided by French local authorities, the theatrical performance “Safe and Sound?” (“Sain et Sauf ?”), and its accompanying debriefing session, was tested in six French Alps municipalities in 2019 and 2020 several 2-day sessions in collaboration with local authorities. 200 people took part in this theatrical performance and interviews. The “Safe and Sound?” scheme is based on a 15-minute play, followed by the collection of data from watching the play and debriefing with an interviewer, during about 30 minutes. Two scenarios on flood risks and on seismic risks were narrated by an actor introducing dilemma. Interviews were transcribed and analysed to determine the level and sources of knowledge about the two natural hazards, and the behaviour during a simulation with an actor. Most participants immediately headed to safety only to later put themselves in danger when confronted with an insistent neighbour and the introduction of emotion-provoking characters, i.e. children. When making their choice at each stimulus, participants evoke different sources of reason. A little under half of participants mention common sense or instinct. Although the majority of participants claim they received preventive information from local authorities, this information is rarely applied. The media and own experience were mentioned more often. Lastly, the “Safe and Sound?” campaign was designed to assess behaviour, but findings show that it was also useful to raise awareness among the population.

Abstract
This study aims to examine the climate change education (CCE) provision in grade 5 textbooks (science and social studies) and the competence of teachers in teaching CCE in a primary girls’ schools in Skardu, Baltistan, Pakistan. It employs mixed-method research that uses both qualitative and quantitative approaches to gather data. The first phase of the study involved collecting qualitative data to examine the provision of CCE content in selected textbooks taught in grade 5. The researcher adapted an interview questionnaire to assess the competence of teachers teaching in 38 schools. The provision of themes and topics based on the seven principles of climate literacy given by the U.S. Global Change Research Program was identified by using latent content analysis (LCA). The study concludes that science and social studies textbooks lack the incorporation of CCE content of principles 1, 4, 6, and 7. Furthermore, the majority of teachers have not received training to use digital media and apply activity-based methods to engage campus and community support for CCE. The study also found that the selected schools lack school planting campaigns, CCE committees, and CCE walks. Above all, the respondents possess conflicting views about whether climate change is a natural or human-contributed phenomenon.
Significance Statement
Like other countries around the globe, Pakistan is the victim of climatic disasters which have disastrous effects on the economy, agriculture, healthcare, and weather conditions. These effects are exacerbated by lacking awareness, attitudinal issues, and poor pro-climate-supported practices at the academic and societal levels (Asian Development Bank 2022). Awareness, knowledge, and a supportive environment during childhood form attitudes and promote practices that have lasting impacts throughout the life of the individual (Gulraiz and Ali 2021). Therefore, children need to learn and adopt proclimate lifestyles, such as observing cleanliness, practicing planting, and judicious use of energy resources. With this background, we assessed the textbooks based on seven principles of climate literacy given by the U.S. Global Change Research Program (USGCRP 2009) and observed that principles 1, 4, 6, and 7 are not adequately addressed in science and social studies textbooks taught in public schools. Moreover, teachers have not received training to use digital media and gather campus and community support, and they have a stereotypical understanding of climate change. The study possesses significant implications for curriculum revisions and elementary education management to address the gaps relating to climate change education (CCE).

Abstract
Rip currents are poorly understood by the public and thus a leading cause of weather-related fatalities in the United States. Individuals who speak languages other than English, such as Spanish-speaking communities, have been historically underserved by communication efforts for natural hazards and thus are at additional risk from rip currents. In response, the National Weather Service (NWS) has developed rip current outreach tools translated into Spanish in recent years, though their efficacy has not been systematically tested. We therefore surveyed members of the Spanish-speaking community in the New York City area to gain insights into how the NWS two-page rip current informational brochure is working and possible improvements to be made. The English version of the brochure was also tested, and the results from the two languages were compared. Quantitative survey results indicate that while both brochures are generally effective, several changes could be made to improve clarity, especially for Spanish speakers, who found more issues with the Spanish version. For example, the translation of the term rip current itself used by the NWS, “corrientes de resaca,” was determined to be confusing by some Spanish speakers, as were other pieces of text with complex scientific terms. Moreover, certain graphics contained in the brochure were difficult to understand for users in both languages. The results of this work can be used by the NWS and other agencies to improve their Spanish risk communication tools and can also be used as a guide when translating scientific information into other languages.
Significance Statement
Rip currents, narrow channels of fast-moving water that can pull swimmers away from the shore, are among the leading weather-related killers in the United States yet are poorly understood by the public. Recent efforts to reduce society’s vulnerability to rip currents include the translation of outreach materials from English to Spanish. This study evaluated a new National Weather Service Spanish rip current informational brochure and compared it to the English version. The results show that while both the English and Spanish brochures were generally effective at communicating risk, the Spanish version had more issues, primarily surrounding the translation of scientific terms and phrases. Findings from this research can help guide scientists in designing improved non-English severe weather outreach products.

Abstract
Prolonged drought poses significant challenges for food and fiber production in the U.S. Southwest, where range livestock production has great economic and cultural significance. Sustaining rangeland agriculture in the region necessitates swift and nimble uptake of drought adaptations. While Extension serves as a promising resource to drought adaptation among ranchers, how Extension staff perceive their capacity to support ranching clientele in that endeavor is not well understood. We interviewed university Extension professionals across New Mexico to explore their perceptions of drought. We found that their perceived ability to aid in drought adaptation was dependent upon interpersonal, as well as structural, factors. These factors differed across ranching regions in New Mexico. This case study highlights the importance of Extension networks, opportunity for novel Extension training, and a need for heightened attention to structural barriers.
