Graduate students can face difficulties collaborating across disciplines and outside of academia. Stakeholder-engaged research (i.e., research involving partners outside of academia) presents challenges for developing a project, finding collaborators, and co-creating knowledge. Past reflections on how to navigate stakeholder-engaged research assume a faculty member leads the project and do not often address implementation from a student-led approach. In this paper, we provide insight on our team science process from an applied, graduate student perspective. We reflect on the formation of our student team and the implementation of a tourism planning research project with community partners. We discuss challenges and focus on practical tips to overcome these challenges. Specifically, we include reflections on co-developing a research project, building authentic partnerships, negotiating power dynamics, and the role of institutional support. Lessons learned from this project can guide other graduate student teams working with stakeholders, as well as faculty seeking to train graduate students in stakeholder-engaged research.

Gender norms and the experiences of women play a pivotal role in shaping the sustainable outcomes of climate change mitigation and food security efforts, particularly in ecologically sensitive areas like the Himalayas. Despite their significance, these dimensions often remain marginalized in policy formulation processes. This research article aims to address this gap by conducting a cross-sectional study in ten villages within the Himalayan region. The study seeks to achieve two primary objectives: (i) assess the impact of climate-induced emergencies on women, and (ii) analyse the gendered norms influencing food choices, with the intent of identifying gender-inclusive measures for climate adaptation and food security. The research employs a mixed-methodology approach, combining quantitative analysis through household surveys (N = 210) with factor analysis, and qualitative insights derived from thematic analysis. The theoretical framework draws on Bourdieu's concept of "field," enabling a nuanced understanding of varied responses to climate change and their underlying rationales. Findings highlight that gender norms exacerbate the vulnerability of women to the impacts of climate change. Additionally, the research underscores the pivotal role of women's traditional knowledge in fostering sustainable food practices and climate adaptation strategies. This study sheds light on the necessity of integrating gender perspectives into policy formation for effective and equitable climate change adaptation and food security strategies in Himalayan communities. Current research underscores the imperative of recognizing and harnessing the experiences and knowledge of women to create holistic and enduring solutions to climate challenges.

The frozen elements of the high North are thawing as the region warms much faster than the global mean. The dangers of sea level rise due to melting glacier ice, increased concentrations of greenhouse gases from thawing permafrost, and alterations in the key high latitude physical systems spurred many authors, and more recently international agencies and supra-state actors, to investigate “emergency measures” that might help conserve the frozen North. However, the efficacy and feasibility of many of these ideas remains highly uncertain, and some might come with significant risks, or could be even outright dangerous to the ecosystems and people of the North. To date, no review has evaluated all suggested schemes. The objectives of this first phase literature survey (which can be found in a separate compendium (https://doi.org/10.5281/zenodo.10602506), are to consider all proposed interventions in a common evaluation space, and identify knowledge gaps in active conservation proposals. We found 61 interventions with a high latitude focus, across atmosphere, land, oceans, ice and industry domains. We grade them on a simple three-point evaluation system across 12 different categories. From this initial review we can identify which ideas scored low marks on most categories and are therefore likely not worthwhile pursuing; some groups of interventions, like traditional land-based mitigation efforts, score relatively highly while ocean-based and sea ice measures, score lower and have higher uncertainties overall. This review will provide the basis for a further in-depth expert assessment that will form phase two of the project over the next few years sponsored by University of the Arctic.

Abstract

Decarbonization policies are frequently combined with other policies to increase public support or address related societal issues. To investigate the consequences of policy bundling, we conducted a survey experiment with 2,521 U.S. adults. We examined the effects of bundling decarbonization with policies favored by liberals (social justice and economic redistribution), broad bipartisan coalitions (infrastructure), and conservatives (pausing EPA regulations) on public support and polarization. Bundling with pausing EPA regulations decreased support and polarization by reducing liberal supportwithout significantly increasing conservative support. Bundling with social justice decreased support while increasing polarization by reducing conservative support without significantly increasing liberal support. Bundling with economic redistribution and infrastructure did not significantly change support or polarization. Policy bundling thus risks decreasing public support for decarbonization policies by alienating one ideological side of the electorate without gaining support from the other side. This risk exists even when policy bundling reduces polarization.

Abstract

Climate change has remarkable global impacts on hydrological systems, prompting the need to attribute past changes for better future risk estimation and adaptation planning. This study evaluates the differences in simulated discharge from hydrological models when driven by a set of factual and counterfactual climate data, obtained using the Inter-Sectoral Impact Model Intercomparison Project's recommended data and detrending method, for quantification of climate change impact attribution. The results reveal that climate change has substantially amplified streamflow trends in the Upper Yangtze and Upper Yellow basins from 1961 to 2019, aligning with precipitation patterns. Notably, decreasing trends of river flows under counterfactual climate have been reversed, resulting in significant increases. Climate change contributes to 13%, 15% and 8% increases of long-term mean annual discharge, Q10, and Q90 in the Upper Yangtze at Pingshan, and 11%, 10%, 10% in the Upper Yellow at Tangnaihai. The impact are more pronounced at headwater stations, particularly in the Upper Yangtze, where they are twice as high as at the Pingshan outlet. Climate change has a greater impact on Q10 than on Q90 in the Upper Yangtze, while the difference is smaller in the Upper Yellow. The impact of climate change on these flows has accelerated in the recent 30 years compared to the previous 29 years. The attribution of detected differences to climate change is more obvious for the Upper Yangtze than for the Upper Yellow.

How do economic shocks affect pressure by the mass public for pro-environmental political action? If democratic systems are to develop and sustain ambitious environmental policy over several decades, this question is important to answer. Theoretically, we argue to look beyond changes in attitudes such as environmental concern, and trace whether and how citizen's policy preferences, and the political importance they attach to environment-related issues change when experiencing a deterioration of their personal economic situation. Empirically, we draw on high-quality population-representative panel survey data for an affluent country, Switzerland, combining tailored survey measures for quasi-random Corona-related employment and income losses, nuanced measures of environmental attitudes and policy preferences, and recently developed measures for issue importance. We neither find a decline of environmental policy support among economically affected individuals compared to the rest of the population (a population wide drop, however), nor lower importance given to environment related relative to economic issues in voting decisions. While this suggests that politicians need not fear electoral losses when pursuing environmental policies in times of economic crisis, we note that the severe extent of the Covid-induced recession, coupled with a rapid recovery, is peculiar to this economic crisis and warrants further research regarding the generalizability of our findings to economic shocks of longer duration.

We conduct a contingent valuation survey in Spain and the UK to elicit information about the Willingness to Pay (WTP) for heat wave watch and response programs. We find that people are willing to pay for such programs, and that the WTP (€ 50 for each of 10 years; 2019 PPP euro) is virtually the same across the two countries and across respondents that received two alternate presentations of the mortality risks with and without the programs. The responses to the WTP questions are internally consistent. Persons who re-assessed their own risks as “very high” after reading the questionnaire’s information about the health effects of excessive heat are prepared to pay more for these programs. These persons are in poor health and less highly educated, and thus an important priority for outreach and education efforts by heat wave watch and response programs. That people value saving lives during heat waves as important is confirmed by the results of person tradeoffs, which show that avoiding a fatality during heat waves is comparable to avoiding a cancer fatality, is slightly more valuable than an avoiding a cardiovascular fatality, and definitely more valuable than an avoided road traffic fatality. The Value per Statistical Life implied by the WTP for the programs is € 1.1 million to € 4.7 million (2019 PPP euro), depending on the size of the mortality risk reduction valued by the respondent, for an average of € 1.6 million.

Nearly 200 governments rely on the Intergovernmental Panel on Climate Change (IPCC) for scientific assessments of climate change. IPCC figures are important for conveying key findings, but can be difficult for policymakers and practitioners to understand. Best practices in graph design, summarized in the IPCC’s visual style guide, recommend conducting interviews with members of the target audience before finalizing figures. Therefore, we interviewed 20 policy makers and practitioners from different countries about three figures drafted for the second order draft of the summary for policymakers associated with IPCC’s Working Group III Sixth Assessment Report. Half were frequent users and half were occasional users of climate science, but similar comments emerged from both groups. The figures received a median rating of 3, on a scale from 1 (= not easy at all to understand) to 5 (= very easy to understand). Showing the caption did not always improve these ratings. Overall, two types of recommendations emerged. First, participants suggested focusing each figure on one key message for policymakers, and removing irrelevant details. For IPCC authors, this involves making hard choices about what to show in the figure and what to leave for the text. Additionally, participants suggested straightforward fixes such as using clear titles, labels, and captions that support the key message. Based on our findings, we present recommendations for the design of climate change figures, and examples of revised figures. These recommendations should be useful for the next round of IPCC reports, and for other organizations that communicate about climate science with policymakers and practitioners.

This paper examines various studies on weather and climate extreme events (WCEE) to identify thematic trends and research gaps and suggest directions for further studies. The review identifies 14 subthemes and 23 research focuses, that address impacts and issues in the pre-, during-, and post-disaster phases. Using a matrix of WCEE dimensionality and content matrix analysis, we analyze the distribution and research focus of these studies, revealing areas with both extensive and limited research. While significant literature exists on certain WCEE subthemes, with a strong focus on damage assessment, spatial extent, losses, and disaster management approaches, only a limited number of studies have explored crucial areas such as risk prediction, urban planning, water quality, urban resilience, and public health dimensions. These areas are vital for effective disaster risk reduction. To bridge the knowledge gaps in these areas and other areas with multi-dimensional outlooks within the context of WCEE, we recommend prioritizing research in these subthemes. Our findings underscore the importance of interdisciplinary collaboration and the need for additional research to enhance our understanding of WCEE. Through evidence-based strategies, policymakers and practitioners can develop measures to enhance resilience and mitigate the impacts of WCEE.

This study aims to explore how climate change education and sensemaking can lead to climate engagement and adaptive behavior at the grassroots level. The research focuses on five rural communities in Ghana and seeks to answer three key questions related to how people understand and respond to climate change issues. One strength of the study is the use of sensemaking as an organizing framework, which allows for a nuanced understanding of how people at the grassroots level make sense of complex environmental issues like climate change. The study findings suggest that sensemaking was a critical factor in how people noticed and made meaning of the climate crisis, and that deliberative tools like storytelling, conversation, and listening were important tools for facilitating this process. We also found that climate educators needed to address existing misconceptions before framing climate change issues in terms of science and impact on livelihoods. Linking climate change to rural livelihoods resonated more with people than science, and a strategy of guiding communities to recognize the need for adaptive behavior through individual and collective sensemaking was important. The emphasis on linking climate change to rural livelihoods rather than science is an important finding, as it suggests that approaches that emphasize the impact of climate change on local communities and their ability to adapt may be more effective than purely scientific arguments.
