Extreme Weather Events and Their Health Impacts: International Variation.

The increasing intensity and frequency of extreme weather events resulting from climate change have led to grid outages and other negative consequences. To ensure the resilience of buildings which serve as primary shelters for occupants, resilient strategies are being developed to improve their ability to withstand these extreme events (e.g., building upgrades and renewable energy generators and storage). However, a crucial step towards creating a resilient built environment is accurately estimating building performance during such conditions using historical extreme climate change-induced weather events. To conduct Building Performance Simulation (BPS) in extreme conditions, such as weather events induced by climate change, it is essential to utilize Actual Meteorological Year (AMY) weather files instead of Typical Meteorological Year (TMY) files. AMY files capture the precise climatic conditions during extreme weather events, enabling accurate simulation of such scenarios. These weather files provide valuable data that can be used to assess the vulnerabilities and resilience of buildings to extreme weather events. By analyzing past events and their impacts using BPS tools, we can gain insights into the specific weaknesses and areas that require improvement. This approach applies to both existing buildings needing climate change-resilient retrofits and new building designs that must be compatible with future climatic conditions. Moreover, the intensification and frequency increase of these extreme weather events makes developing adaptation and resilient-building measures imperative. This involves understanding the potential losses that households may experience due to the intensification of extreme events and developing farsighted coping strategies and climate-proof resilient-building initiatives. However, addressing the knowledge gap caused by the absence of an AMY weather file dataset of extreme events is essential. This will allow for accurate BPS during past extreme climate change-induced weather events. To fill this gap, this article introduces a comprehensive .epw format weather file dataset focusing on historical extreme weather events in Canada. This collection encompasses a diverse array of past extreme climate change occurrences in various locations, with potential for future expansion to include additional locations and countries. This dataset enables energy simulations for different types of buildings and considers a diverse range of historical weather conditions, allowing for better estimation of thermal performance.

Recent experience from Hurricane Sandy and high-temperature episodes has clearly demonstrated that the health of New Yorkers can be compromised by extreme coastal storms and heat events. Health impacts that can result from exposure to extreme weather events include direct loss of life, increases in respiratory and cardiovascular diseases, and compromised mental health. Other related health stressors—such as air pollution, pollen, and vector-borne, water-borne, and food-borne diseases—can also be influenced by weather and climate. Figure 5.1 illustrates the complex pathways linking extreme weather events to adverse health outcomes in New York City. New York City and the surrounding metropolitan region face potential health risks related to two principal climate hazards: (1) increasing temperatures and heat waves, and (2) coastal storms and flooding. The health impacts of these hazards depend in turn on myriad pathways, the most important of which are illustrated in the figure. Figure 5.1 Pathways linking climate hazards to health impacts in New York City. Although New York City is one of the best-prepared and most climate-resilient cities in the world, there remain significant potential vulnerabilities related to climate variability and change. As part of the NPCC2 process, a team of local climate and health specialists was mobilized to assess current vulnerabilities and to identify strategies that could enhance the resilience of New York City to adverse health impacts from climate events. The goal was to highlight some of the important climate-related health challenges that New York City is currently facing or may face in the future due to climate variability and change, based on emerging scientific understanding. As indicated in Figure 5.1, health vulnerabilities can be magnified when critical infrastructure is compromised. Critical infrastructure is a highly complex, heterogeneous, and interdependent mix of facilities, systems, and functions that are vulnerable to a wide variety of threats, including extreme weather events. For example, delivery of electricity to households depends on a multi-faceted electrical grid system that is susceptible to blackouts that can occur during heat waves. These, in turn, can expose people to greater risk of contact with exposed wires or to greater heat stress due to failure of air conditioning. Understanding and predicting the impacts that extreme weather events may have on health in New York City require careful analysis of these interactions. Two recent plans to enhance climate resiliency in New York City have been released. A Stronger, More Resilient New York (City of New York, 2013) was developed in the aftermath of Hurricane Sandy by a task force of representatives from City agencies and consultants. This plan was informed by a detailed analysis of the impacts of Hurricane Sandy on infrastructure and the built environment and by the NPCC’s updated 2013 climate projections for the New York metropolitan region. It includes more than 250 initiatives and actionable recommendations addressing 14 domains of the built environment and infrastructure including the healthcare system and several other domains relevant to protecting public health. In addition, the 2014 New York City Hazard Mitigation Plan (HMP) (City of New York, 2014), developed by the NYC Office of Emergency Management in collaboration with the Department of City Planning, updated the 2009 HMP and assesses risks from multiple hazards that threaten New York City. These include but are not limited to several climate-related hazards such as coastal storms and heat waves, and it lays out comprehensive strategies and plans to address these hazards. Many of the measures recommended by A Stronger, More Resilient New York and the HMP have already been implemented, are in progress, or are planned (City of New York, 2013; 2014). This chapter does not include a detailed review of these plans, which would be beyond the expertise and charge of the contributors. Nonetheless, the recommendations in this chapter do broadly support the plans laid out in A Stronger, More Resilient New York and the 2014 HMP, and these are referenced at several points where they are especially relevant. Here we focus on summarizing and synthesizing the emerging scientific knowledge on climate-related health hazards, knowledge that can inform ongoing preparedness planning. Key terms related to climate variability and change as they are applied in the health sector are defined in Box 5.1. This is followed by sections describing health risks, vulnerabilities, and resilience strategies for coastal storms and extreme heat events. We then briefly discuss the interactions of climate change with air pollution, pollen, vector-borne diseases, and water- and food-borne diseases. We conclude with recommendations for research and resiliency planning. Box 5.1 Definitions of key cross-cutting terms in the health context Adaptation Initiatives and measures to reduce the vulnerability of natural and human systems against actual or expected climate change effects. Various types of adaptation exist, such as anticipatory and reactive, private and public, and autonomous and planned. For health, physiological adaptation is also relevant.

BACKGROUND: Island communities such as Puerto Rico (PR) are profoundly impacted by climate extremes. Patients with chronic disease, particularly cancer, have unique needs and challenges in the aftermath of extreme weather events. Understanding cancer patients’ barriers, knowledge, risks, and vulnerabilities are essential to develop equitable adaptation strategies. This research aims to investigate the perceptions and experiences of cancer patients associated with extreme weather events over the past 10 years in Puerto Rico (PR). METHODS: We conducted a cross-sectional study via survey questionnaires (April 22, 2023-June 8, 2023) among adults aged ≥21 years from Puerto Rico who are cancer patients/survivors (n=207). A total of 23 questions listed on the survey were used to collect information on variables of interest which included demographic characteristics, information on extreme weather event experiences, and attitude towards climate change. Using the data collected, descriptive statistics were used to describe the study population and multivariable logistic regression models were used to evaluate the associations of interest (IRB approval # 2023-04-101). RESULTS: The average age of individuals recruited is 56.3 years ±13.5 SD, 79.7% are female, 65.2% reported having additional chronic diseases, and 85.0% have more than a high-school education. Regarding extreme weather events, 99% of cancer patients and survivors reported floods, including coastal, fluvial, and urban floods, impacted their communities, 76% reported tropical cyclones impacted their residences and communities, and 72% reported extreme heat impacted both their residences and communities in the last 10 years. Additionally, the most common problems encountered in the aftermath of these extreme weather events were water (88.4%) and electricity service interruption (91.4%), as well as water (88.9%) and electricity service interruption (77.1%). Most participants reported feeling very and extremely worried about their health in the face of climate change (75.0%) and feeling concerned about climate change (85.0%). After adjusting for age, sex, and education, logistic regression models showed that participants with more than one cancer type were more likely to be worried about their health in the face of climate change (OR=2.40,95% CI=1.06-5.35). CONCLUSION: Study findings highlight the burden of extreme weather events and the problems encountered in the aftermath of such events on cancer patients in Puerto Rico. This population expresses concern and worry about climate change and their health, respectively. This information is important for cancer control and emphasizes the need for targeted interventions and management strategies to remove detrimental and avoidable impacts on cancer populations.

Climatic changes lead to many extreme weather events throughout the globe. These extreme weather events influence our behavior, exposing us to different environmental conditions, such as poor indoor quality. Poor indoor air quality (IAQ) poses a significant concern in the modern era, as people spend up to 90% of their time indoors. Ventilation influences key IAQ elements such as temperature, relative humidity, and particulate matter (PM). Children, considered a vulnerable group, spend approximately 30% of their time in educational settings, often housed in old structures with poorly maintained ventilation systems. Extreme weather events lead young students to stay indoors, usually behind closed doors and windows, which may lead to exposure to elevated levels of air pollutants. In our research, we aim to demonstrate how real-time monitoring of air pollutants and other environmental parameters under extreme weather is important for regulating the indoor environment. A study was conducted in a school building with limited ventilation located in an arid region near the Red Sea, which frequently suffers from high PM concentrations. In this study, we tracked the indoor environmental conditions and air quality during the entire month of May 2022, including an extreme outdoor weather event of sandstorms. During this month, we continuously monitored four classrooms in an elementary school built in 1967 in Eilat. Our findings indicate that PM2.5 was higher indoors (statistically significant) by more than 16% during the extreme event. Temperature was also elevated indoors (statistically significant) by more than 5%. The parameters’ deviation highlights the need for better indoor weather control and ventilation systems, as well as ongoing monitoring in schools to maintain healthy indoor air quality. This also warrants us as we are approaching an era of climatic instability, including higher occurrence of similar extreme events, which urge us to develop real-time responses in urban areas.

Climate change represents the greatest threat to human health, with both direct and indirect effects.  The direct increase of deaths, due to extreme weather and climate events, the emergence and spread of infectious diseases related to changing temperature, habitat and precipitation patterns, and eventually climate shocks and growing stress and anxiety that are affecting mental health. Moreover, extreme weather events cause issues on our health systems and infrastructures, reducing capacity to provide health coverage.   An increasing awareness on adverse effects of climate change is leading to an update of the EU policy framework through the introduction of  the EU Green Deal, a ‘package’ of directive, policies and strategies to ensure planning, monitoring and reporting of progress towards responsive climate adaptation and climate neutrality; however, a clear demonstration of the health-relevant outcomes of climate policies and actions is still missing, and current policies do not properly consider human health protection.   The study is developed within the Horizon Europe-funded project TRIGGER, aimed at deepening the understanding of the linkage between climate change and health and advancing society uptake at policy level.  Starting from mapping and screening the existing climate-related policies and measures at European level, this study assesses the integration of health in such documents. Specifically, through a keyword-based content analysis, it evaluates the integration of health-relevant considerations in 11 European plans and strategies, referring to climate mitigation and adaptation, environmental sustainability and biodiversity conservation. To establish to what extent they consider the direct and indirect impacts of climate change on human health, a qualitative assessment of health integration is performed, exploring also, when available, cost-benefits estimation to possible health impacts and health-related indicators developed.   The results show that extreme events, such as heat waves and droughts, heavy precipitation and flooding, are the climate-related hazards mostly mentioned in relation to health, even though the policy integration remains limited. Indeed, just few policies contain references to physical health impacts determined by climate change, such as infectious and vector borne diseases, injuries from extreme weather events and cardiovascular and respiratory diseases, while social and mental health effects are even less considered.    

<p>Compound events lead to substantial risks to societies around the globe. As climate change is increasingly exacerbating the intensity and frequency of many hazards in vulnerable regions, ex situ responses to climate change including human mobility and displacement are starkly moving into the spotlight. Whilst proactive migration is often used as an adaptation response to the impact of climate and weather events, reactive migration following unprecedented climatic shocks is often involuntarily and can seriously disrupt livelihoods and undermine human security. The extent to which human mobility (here, measured by internal displacement) can be attributed to extreme weather and compound events and in turn, whether and to what extent extreme weather events and consequently human mobility can be attributed to anthropogenic climate change, has been largely unexplored. </p><p>Applying a framework based on probabilistic event attribution (PEA) of extreme weather events, we investigate, for the first time, human mobility responses attributed to anthropogenic climate change along a causal chain from anthropogenic climate change and changing frequencies and intensities of extreme weather and climate events to human mobility outcomes. We use the April 2020 extreme precipitation which lead to flooding and associated displacement in Somalia as a feasibility study to present the state of the art of this method. Our attribution model investigates two locations: First, we attribute extreme precipitation at the origin region of the extreme event to then attribute the resulting flood event in the displacement impact region. Event though the analysis shows no attributable link to anthropogenic climate change, our method advances the field of climate impact research regarding statistical approaches, model development and evaluation. For our feasibility study, we also find that sparsity of climate observations reveal one of many reasons for a lack of a climate change signal, which suggests an application of our model to other climate event contexts is needed to further test our method.</p>

Climate Change and Human Health in China

Left unmitigated, climate change poses a catastrophic risk to human health, requiring an urgent and concerted response from every country. As the home to one fifth of the world's population and the largest emitter of carbon dioxide globally, China's interventions in climate change are of pivotal importance, both to human health and to the planet. Similar to other countries, climate change mitigation and adaptation would bring immense health benefits for China's 1·4 billion people, and building these considerations into any COVID-19 recovery strategy and the detailed pathway to fulfil the 2060 carbon neutrality pledge will ensure it improves human wellbeing, both now and in the future. Decisions made over the coming months and years will establish the course of climate change policy for decades to come. To meet this challenge, Tsinghua University (Beijing, China), partnering with University College London (London, UK) and 17 Chinese and international institutions, has produced the Lancet Countdown China report, focusing at the national level and building on the work of the global Lancet Countdown. Drawing on international methods and frameworks, this report aims to understand and track the links between public health and climate change at the national level. This paper is one part of the Lancet Countdown's broader efforts to develop regional expertise and understanding. Uniquely, the data and results in this report are presented at the provincial level where possible, to facilitate the targeted response strategies for local decision makers. Taken as a whole, the findings of the 23 indicators convey two key messages. The first message is that the health effects from climate change in China are accelerating, posing an unacceptably high amount of health risk if global temperatures continue to rise. Every province is affected, each with its unique health threats, and targeted response strategies should be made accordingly. The effects of climate change, manifested in rising temperatures, more extreme weather events, and shifting vector ecology, are being felt in China. Heatwave-related mortality has risen by a factor of four from 1990 to 2019, reaching 26 800 deaths in 2019. The monetised cost of the high number of deaths is equivalent to the average annual income of 1·4 million people in China. Older people (>65 years old), who face a 10·4% higher risk of dying during a heatwave, endured an average of 13 more heatwave days in 2019 compared with the 1986–2005 baseline. For outdoor workers, their potential heat-related labour productivity loss reached 0·5% of total national work hours, costing 1% of China's gross domestic product (GDP), equivalent to its annual fiscal expenditure on science and technology. Driven in part by rising temperatures and a changing climate, the advent of more extreme wildfires and the spread of dengue fever will in turn lead to profound health effects. Different regions have unique health threats, requiring a targeted response—19 provinces have had an at least 10% rise over the past two decades in three or more of the six health effect indicators reported. Importantly, many highly populated and economically advanced provinces, such as Henan, Shandong, and Zhejiang, are faced with health risks that are larger and more rapidly accelerating than others. The second message is that impressive and concerted improvements have been made across several sectors in China; however, the gap in the country's response to the health effects of climate change is large. In some sectors, China has taken large steps to address climate change. Solar power generation is growing at an unprecedented rate of 26·5% per year, rising to 26·8 gigawatts (GW) of newly installed capacity in 2019. Investments in low-carbon energy are now nine times greater than those in fossil fuels (rising from a 1:1 ratio in 2008); and, providing 4·1 million jobs in 2018, renewable energy now employs more people in China than fossil fuel extraction industries. As a result of strong policy measures, severe air pollution has also decreased, with a 28% reduction in annual average particulate matter of 2·5 μm or less (PM2·5) concentration in cities from 2015 to 2019, resulting in 90 000 fewer PM2·5-related premature deaths annually. These air pollution control policies also act to mitigate climate change and have resulted in a decline in China's coal share in total primary energy supply from 66% in 2014 to 59% in 2018. Showing leadership at the subnational level, three provinces already have a provincial health and climate change plan in place, with four more provinces underway. However, although these changes have been rapid, more shifts of a greater size are necessary to enact a response that is of the scale required to fulfil China's carbon neutrality by 2060 pledge and to minimise the rising health burdens of climate change, both in China and around the world. Although renewable energy use is rising, coal stills holds a 59% share of the total primary energy supply in China. Fossil fuel subsidies were US$41·9 billion in 2018, without considering the contribution of fossil fuels to the estimated $10·7 billion economic losses because of premature mortality from PM2·5 air pollution. Although there have been substantial reductions in air pollution, 42% of China's population still live in areas that do not meet the interim air quality guidelines from WHO, and almost all cities have PM2·5 concentrations more than the recommended annual average of 10 μg/m3. The health effects of climate change are not adequately recognised or addressed, as climate change is not referenced in the Healthy China Action Plan (2019–30), and China is yet to introduce a standalone national adaptation plan for health. Taking a broader perspective, media coverage and individual engagement in health and climate change are low, with little spread of knowledge and engagement. China will need to scale up progress in all sectors to counteract the rising curve of the health risks from climate change. Five recommendations are proposed to key stakeholders in health and climate change in China: (1)Enhance interdepartmental cooperation. Climate change is a challenge that requires an integrated response from all sectors. Although China commits to integrate health into all policies, substantial interdepartmental cooperation among health, environment, energy, economic, financial, and education authorities is urgently needed.(2)Strengthen health emergency preparedness. Although the amount of health emergency preparedness in China would be greatly enhanced after COVID-19, knowledge and findings on current and future climate-related health threats still do not have enough attention and should be fully integrated into the emergency preparedness and response system, so that future health service, medical supplies, and infrastructure needs could be planned ahead.(3)Support research and raise awareness. Additional financial support should be allocated to health and climate change research in China, to enhance the knowledge of health system adaptation, mitigation measures, and their resulting health benefits. At the same time, media and academia should be fully motivated to raise awareness on this topic for the public and for politicians. Additionally, the Government of China should update the Healthy China Action Plan (2019–30) to address the health risks of climate change as soon as possible.(4)Increase climate change mitigation. China's new pledges towards carbon neutrality by 2060 is a major step forward. Speeding up the coal phase-out process is therefore necessary to be consistent with the carbon neutrality pledges and continue China's progress on air pollution reduction. Fossil fuel subsidies should also be phased out to reflect the true cost of ongoing fossil fuel use and to avoid undermining the effect of China's emissions trading scheme, scheduled to take effect in 2021.(5)Ensure the country's recovery from the COVID-19 pandemic protects health both now and in the future. Decisions made as part of China's efforts to recover from COVID-19 will shape the public's health for years to come. The longer-term prospects for lives, livelihoods, and a sustainable economy will be put in jeopardy if these interventions do not prioritise climate change.

In recent years, extreme weather events have led to more frequent coverage of climate change in many media outlets than it was previously the case. They are seen as chance for making climate change tangible and visible to the public, potentially catalyzing action across all levels of society. However, the reporting of such events also poses risks, for example the skewed emphasis on consequences over causes and solutions. The coverage of extreme weather events also carries the risk that media attention towards climate change fades away immediately once the event is over.Previous research demonstrates that individuals' experiences of weather indeed serve as a 'sense-making device' for climate change (i.e., "You can see from the many warm winters that climate change exists"). Personal weather experiences are interpreted within the framework of existing attitudes towards climate change and have intersections and overlay-effects with media experiences ('media frames’). For example, the more an extreme weather event is discussed in context of climate change – especially within socially-relevant groups – the more it can affect climate change awareness. The state of research stresses the important role of weather forecasting in bridging the distance towards the issue and demonstrating the personal and local relevance. In this talk, the research question is addressed how TV coverage of extreme weather events in the year 2022 was perceived by audiences. How did it effect the audiences’ climate change awareness?To answer the research question, an empirical study about German TV-audiences, which was conducted in October 2022. It includes a series of focus group discussions (n=42, period 26.-29.02.2022), and an online-survey ((n=1.145, October 2022), representative for Germany, and with a focus on extreme weather events. The results underline that personal experiences of such extreme events and media representations play pivotal roles in shaping individuals' perceptions of climate change. Approximately 50% of respondents reported a shift in their perception of climate change following the extreme weather events in summer 2022, with 37% attributing this change to media coverage. Through exploratory factor analysis, it becomes evident that media coverage of extreme weather reduces the perceived distance to the issue on multiple dimensions. Moreover, there exists a significant correlation between the perceived influence of media coverage and personal experiences of extreme weather events, suggesting a mutually reinforcing relationship between own observation and media portrayal. This reciprocal influence extends beyond mere perception, with media coverage of extreme weather events impacting individuals on multiple levels. The reporting of such events intensifies the immediacy of climate change, making it feel more tangible and immediate in people's lives and those of their closest social circles. Additionally, it heightens the perceived likelihood of climate-related occurrences and accelerates the perceived proximity of their consequences. These findings underscore the profound impact of media narratives in bringing the issue of climate change closer to individuals' lived experiences.

It is a perilous time to be a farmer. Across the world, 2015 broke records for unseasonal, unprecedented, and unexpected weather. The combination of El Nino and climate change produced conditions with devastating effects for the agriculture sector around the globe. This article examines the impacts of unseasonal weather on farmers around the world, in losses to yield quality and quantity but also in economic, physical and psychological effects for farmers coping with the “new normal” in weather. It considers regional differences in farmers’ susceptibility to unseasonal weather, and presents the implications of the lack of resiliency of the major crop producers for the future of food security, and by extension, political stability. Finally, it looks at how the international community is addressing this situation, concluding with practical and achievable means for farmers and cooperatives to start to build resiliency to climate change today.

CONTENTS I Introduction II Climate Change and Extreme Weather Events III Adaptation in the International Climate Regime IV Insurance and Adaptation in the International Climate Regime V Models for Climate Change Insurance VI Caribbean Catastrophe Risk Insurance Facility VII Climate Change Insurance and the Pacific Island States VIII Viability of Climate Insurance as a Long-Term Adaptation Strategy IX Conclusion I INTRODUCTION Many Small Island Developing States ('SIDS') lie only metres above sea level, making them particularly vulnerable to the impacts of climate change in both the shorter (eg storm surge during large tropical cyclones) and longer (eg sea level rise) terms. (1) The modest ambition for mitigation (ie reduction) (2) of greenhouse gas emissions in the United Nations Framework Convention on Climate Change ('UNFCCC'), (3) Kyoto Protocol (4) and Copenhagen Accord (5) means that the prospect of avoiding an increase in mean surface temperature of less than two degrees is now very low. (6) The latest climate science suggests the Earth is on a path that will lead to a rise in mean surface temperature of between three and six degrees by 2100. (7) Unless there is a significant reduction in greenhouse gas emissions over coming decades, SIDS are likely to experience tropical cyclones of greater severity, disrupted rainfall patterns and sea level rise. (8) Recent extreme weather events in the Asia-Pacific region, such as Typhoon Haiyan (9) and Cyclone Ian, (10) demonstrate the significant impact of these events on SIDS. (11) The lack of success in mitigating greenhouse gas emissions has led to adaptation to climate change impacts gaining greater prominence within the United Nations climate negotiations. Adaptation to climate change has been defined as '[a]djustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities'. (12) Adaptation may take many forms, including pre-emptive action to limit damage from climate change-related events (eg implementing more ambitious building codes to make buildings more resilient to storms) and building institutions to aid recovery after a climate-related event (eg improving emergency services capacity to respond in the immediate aftermath of adverse weather events). Domestically, insurance is an established mechanism to spread financial risk of adverse events and build societal resilience. However, at an international level, the issue of climate change-related insurance has only proceeded in fits and starts. Proposals for an insurance mechanism to support the adaptation of SIDS to climate change date back to 1991. At that time, the Alliance of Small Island States ('AOSIS') proposed an international, state-based pool to provide insurance against the impacts of climate change-related sea-level rise. (13) Despite this early call by AOSIS, a climate change-related insurance mechanism was not included in either the UNFCCC or the Kyoto Protocol. In 2007 climate change-related insurance emerged again on the UNFCCC agenda as the Bali Action Plan launched international discussion on enhanced action on adaptation 'including risk sharing and transfer mechanisms such as insurance'. (14) In 2008 AOSIS made a submission under the Bali Action Plan to include an insurance mechanism as part of a broader response to climate-related loss and damage. (15) In a departure from its earlier proposal in 1991, the 2008 AOSIS submission called for insurance cover for climate change-related extreme weather events such as hurricanes, floods and droughts. (16) In 2010 the Cancun Agreements also invited submissions on the development of a climate risk insurance facility, as a part of an enhanced adaptation framework, to address impacts from extreme weather events. (17) The 2012 Conference of the Parties ('COP') 18 meeting in Doha appeared to be a breakthrough in the development of institutions to assist adaptation to climate change. …

Assessment and planning for emerging impacts of climate change on species

Economic and sustainability promises of wind energy considering the impacts of climate change and vulnerabilities to extreme conditions

Both climate scientists and non-scientists (laypeople) attribute extreme weather events to various influences. Laypeople’s attributions for these events are important as these attributions likely influence their views and actions about climate change and extreme events. Research has examined laypeople’s attribution scepticism about climate change in general; however, few climate scientists are familiar with the processes underpinning laypeople’s attributions for individual extreme events. Understanding these lay attributions is important for scientists to communicate their findings to the public. Following a brief summary of the way climate scientists calculate attributions for extreme weather events, we focus on cognitive and motivational processes that underlie laypeople’s attributions for specific events. These include a tendency to prefer single-cause rather than multiple-cause explanations, a discounting of whether possible causes covary with extreme events, a preference for sufficient causes over probabilities, applying prevailing causal narratives, and the influence of motivational factors. For climate scientists and communicators who wish to inform the public about the role of climate change in extreme weather events, these patterns suggest several strategies to explain scientists’ attributions for these events and enhance public engagement with climate change. These strategies include showing more explicitly that extreme weather events reflect multiple causal influences, that climate change is a mechanism that covaries with these events and increases the probability and intensity of many of these events, that human emissions contributing to climate change are controllable, and that misleading communications about weather attributions reflect motivated interests rather than good evidence.

Policy making under scarcity: reflections for designing socially just climate adaptation policy
