Dichotomy or continuum? A global review of the interaction between autonomous and planned adaptations
Adaptation to climate change is often conceptualized as a dichotomy, with responses being either planned (formal and structured) or autonomous (organic and self-organized, often known as “everyday adaptation”). Recent literature on adaptation responses has highlighted the existence and importance of the interplay between autonomous and planned adaptation, but examination of this interaction has been limited to date. We use a global database of 16…
Interactions between indoor heat and energy affordability amplify household risks in hot-humid US climate zones
Navigating justice tensions in managed retreat
Research priorities for climate mobility
The escalating impacts of climate change on the movement and immobility of people, coupled with false but influential narratives of mobility, highlight an urgent need for nuanced and synthetic research around climate mobility. Synthesis of evidence and gaps across the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report highlight a need to clarify the understanding of what conditions make human mobility an effective adaptation…
Defining “climatopia”
Housing amenity and affordability shape floodplain development
Flood damage has severe and long-term repercussions for households and communities, and continued housing development in floodplains escalates damages over time. Policies and interventions to reduce damage depend on assumptions about housing stock and residents, but assessments of flood exposure to date largely focus on community-scale characteristics at a single point in time, masking potential within-community differences and their evolution th…
A global assessment of actors and their roles in climate change adaptation
An assessment of the global progress in climate change adaptation is urgently needed. Despite a rising awareness that adaptation should involve diverse societal actors and a shared sense of responsibility, little is known about the types of actors, such as state and non-state, and their roles in different types of adaptation responses as well as in different regions. Based on a large n -structured analysis of case studies, we show that, although …
Status of global coastal adaptation
A research agenda for the science of actionable knowledge
Linking science with action affords a prime opportunity to leverage greater societal impact from research and increase the use of evidence in decision-making. Success in these areas depends critically upon processes of producing and mobilizing knowledge, as well as supporting and making decisions. For decades, scholars have idealized and described these social processes in different ways, resulting in numerous assumptions that now variously guide…
Modes of climate mobility under sea-level rise
Exposure to sea-level rise (SLR) and flooding will make some areas uninhabitable, and the increased demand for housing in safer areas may cause displacement through economic pressures. Anticipating such direct and indirect impacts of SLR is important for equitable adaptation policies. Here we build upon recent advances in flood exposure modeling and social vulnerability assessment to demonstrate a framework for estimating the direct and indirect …
Effective climate change adaptation means supporting community autonomy
Functionality‐based life cycle assessment framework
Life cycle assessment (LCA) has been widely applied to assessing the environmental impacts of information and communication technologies (ICT) products throughout their lifetime. Building upon LCA methodology, this study proposes a user‐oriented, functionality‐based LCA (FLCA) framework that evaluates the environmental impact of multifunctional ICT products such as smartphones. Incorporating the quality function deployment and LCA literature, we …

Enhancing the review process in global environmental assessments
External review is a fundamental component of Global Environmental Assessments, ensuring their processes are comprehensive, objective, open and transparent, and are perceived as such. Here, we focus on review of Intergovernmental Panel on Climate Change (IPCC) Assessment Reports. The review process has received little scrutiny, although review comments and author responses are public. Here we analyse review documents from the Fourth and Fifth Ass…
News media coverage of Covid-19 public health and policy information
During a pandemic, news media play a crucial role in communicating public health and policy information. Traditional newspaper coverage is important amidst increasing disinformation, yet uncertainties make covering health risks and efforts to limit transmission difficult. This study assesses print and online newspaper coverage of the coronavirus disease COVID-19 for March 2020, when the global pandemic was declared, through August 2020 in three c…
A systematic global stocktake of evidence on human adaptation to climate change
A framework for complex climate change risk assessment
Real-world experience underscores the complexity of interactions among multiple drivers of climate change risk and of how multiple risks compound or cascade. However, a holistic framework for assessing such complex climate change risks has not yet been achieved. Clarity is needed regarding the interactions that generate risk, including the role of adaptation and mitigation responses. In this perspective, we present a framework for three categorie…
Equity in human adaptation-related responses
Promoting equity in retreat through voluntary property buyout programs
Voluntary property buyouts have been the most prevalent form of managed retreat in the USA to date. Tens of thousands of households have sold their flood-prone homes to the government, and after the structures are demolished, the land becomes open space. Concerns have been raised about the equity of buyout processes and outcomes, spanning distributive, procedural, and interactional dimensions of social justice. In this policy analysis, we first p…
The role of international organizations in equitable and just planned relocation
Since 2010, States party to the United Nations Framework Convention on Climate Change have recognized planned relocation as a viable adaptation to climate change. Planned relocation has been attempted in many communities globally and has raised serious issues of equity in some cases. Implementation driven by principles of equity is crucial in ensuring successful planned relocations that decrease loss and damage. In this Policy Analysis, we put fo…
Climate mobility and the pandemic
Societies were underprepared for the COVID-19 pandemic. This is also the case for climate change. Art may have a greater role to play in advancing societal resilience across these different categories of shocks and risks. In this Intervention, we deploy and evaluate art as a social practice supporting societal responses to sea level rise and its impacts. Our evaluation is focused on the ways in which the open-ended, deliberately unusual juxtaposi…
Whose voices, whose choices? Pursuing climate resilient trajectories for the poor
Climate Resilient Trajectories are routes to development progress that take into account aspects of climate change adaptation and mitigation in a sustainability context, offering a way to explicitly consider impacts of development and climate change choices on different sectors, scales, and socio-economic effects. Due to their scope and relevance, Climate Resilient Trajectories are of great interest to climate scientists, governments and the priv…
A “precariously unprepared” Pentagon? Climate security beliefs and decision-making in the U.S. military
Increasing evidence suggests that climate change poses direct and indirect threats to national and human security. However, the degree to which such knowledge of the risks informs decision-making remains poorly understood for key security communities, including the U.S. Department of Defense. Here, through document analysis and interviews with climate security researchers and practitioners from the U.S. military community, we evaluate perceptions…
Science-policy dimensions of research on climate change and conflict
A large body of research now indicates that climate likely matters for conflict. This climate-conflict scholarship, however, has involved divergent findings, sometimes strident disagreement, and resulting limits to the usability of the scholarship for policymakers and practitioners. This viewpoint essay draws from recent expert assessments of climate-conflict linkages to position the research field among climate change research and assessment mor…

To co-produce or not to co-produce
Actionable knowledge and the art of engagement
Great expectations? Reconciling the aspiration, outcome, and possibility of co-production
Unleashing expert judgment in assessment
Assessment evaluates accumulated knowledge and its limits. It informs and ideally empowers decisions and actions on complex, contested issues with persistent uncertainties. Applying rigorous expert judgment is an important dimension of assessment. Here we evaluate advances and challenges in approaches to expert judgment in the Intergovernmental Panel on Climate Change's Fifth Assessment Report (IPCC AR5). We find that revised guidance for author …

Summary for Policymakers
This Summary for Policymakers presents key findings from the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX). The SREX approaches the topic by assessing the scientific literature on issues that range from the relationship between climate change and extreme weather and climate events ("climate extremes") to the implications of these events for society and sustainable development. The…
Flood risk and climate change
A holistic perspective on changing rainfall-driven flood risk is provided for the late 20th and early 21st centuries. Economic losses from floods have greatly increased, principally driven by the expanding exposure of assets at risk. It has not been possible to attribute rain-generated peak streamflow trends to anthropogenic climate change over the past several decades. Projected increases in the frequency and intensity of heavy rainfall, based o…

Net-zero emissions energy systems
Path to zero carbon emissions Models show that to avert dangerous levels of climate change, global carbon dioxide emissions must fall to zero later this century. Most of these emissions arise from energy use. Davis et al. review what it would take to achieve decarbonization of the energy system. Some parts of the energy system are particularly difficult to decarbonize, including aviation, long-distance transport, steel and cement production, and …

Factors influencing adoption and rejection of fire hazard severity zone maps in California
Community wildfire preparedness programs are an important means of protecting residents living in hazardous areas like the wildland-urban interface. Different programs rely on various sets of drivers, such as legal enforcement or engaged citizens. Here, sociopolitical motivations and barriers for participation are evaluated in a state-recommended, though not legally required, local program in California (Very High Fire Hazard Severity Zones).
