Flood risk to single-family rental housing remains poorly understood, leaving a large and increasing population underinformed to protect themselves, including regarding insurance. This research introduces a life-cycle benefit-cost analysis for the landlord, tenant, and insurer [i.e., (U.S.) National Flood Insurance Program (NFIP)] to optimize freeboard [i.e., additional first-floor height above the base flood elevation (BFE)] selection for a rental single-family home. Flood insurance premium; apportioned flood risk among the landlord, tenant, and NFIP by insurance coverage and deductible; rental loss; moving and displacement costs; freeboard construction cost; and rent increase upon freeboard implementation are considered in estimating net benefit (NB) by freeboard. For a 2,500 square-foot case study home in Metairie, Louisiana, a two-foot freeboard optimizes the combined savings for landlord and tenant, with joint life-cycle NB of $23,658 and $14,978, for a 3% and 7% real discount rate, respectively. Any freeboard up to 2.5 feet benefits the tenant and NFIP, while the landlord benefits for freeboards up to 4.0 feet. Collectively, results suggest that at the time of construction, even minimal freeboard provides substantial savings for the landlord, tenant, and NFIP. The research provides actionable information, supporting the decision-making process for landlords, tenants, and others, thereby enhancing investment and occupation decisions.

Net zero targets have rapidly become the guiding principle of climate policy, implying the use of carbon dioxide removal (CDR) to compensate for residual emissions. At the same time, the extent of (future) residual emissions and their distribution between economic sectors and activities has so far received little attention from a social science perspective. This constitutes a research gap as the distribution of residual emissions and corresponding amounts of required CDR is likely to become highly contested in the political economy of low-carbon transformation. Here, we investigate what function CDR performs from the perspective of sectors considered to account for a large proportion of future residual emissions (cement, steel, chemicals, and aviation) as well as the oil and gas industry in the EU. We also explore whether they claim residual emissions to be compensated for outside of the sector, whether they quantify these claims and how they justify them. Relying on interpretative and qualitative analysis, we use decarbonization or net zero roadmaps published by the major sector-level European trade associations as well as their statements and public consultation submissions in reaction to policy initiatives by the EU to mobilize CDR. Our findings indicate that while CDR technologies perform an important abstract function for reaching net zero in the roadmaps, the extent of residual emissions and responsibilities for delivering corresponding levels of negative emissions remain largely unspecified. This risks eliding pending distributional conflicts over residual emissions which may intersect with conflicts over diverging technological transition pathways advocated by the associations.

Climate change adaptation is a maturing field of research imbued with many complexities and tensions. In this article, we outline five tensions that we observe in our own adaptation research. These are between: adaptation as a research topic and practical challenge; uncertainty in adaptation research and decision-makers' desire for certainty; the global scope of adaptation research and its highly context-specific nature; the newness of climate adaptation research and its push to address old problems; adaptation as a specialization and the need for all researchers to engage. Our aim is to encourage critical discussion and reflection among researchers about how adaptation research is positioned within, shaped by and influences social and institutional settings. Given its emplaced character, adaptation research needs to attend to its content and context.

Increasing sea levels and water temperatures have been detected at several coastal locations worldwide with severe consequences on the communities and ecosystems. Coastal lagoons are particularly vulnerable to such changes due to their low land elevation and limited connections with the open sea. Here the recent and future climatic changes in the Lagoon of Venice (Italy) are investigated using in-situ observations and high-resolution hydrodynamic modeling. Trend analysis was applied to observed time series of meteorological and oceanographic climate essential variables to identify significant long-term changes in mean and extreme values. The mean relative sea level rose at a rate of 4.9 mm per year in Venice due to the combined action of eustacy and subsidence while air and sea temperatures increased on average by 1.8 and 1.1°C in 30 years, respectively. These rates, as well as climate projections, were used following a pseudo-global-warming approach to investigate the near future (up to 2050) evolution of the lagoon's dynamics focusing on sea level and temperature extremes. The lagoon will amplify the temperature changes expected for the Adriatic Sea, especially in the shallow tidal flats where the intensity of the marine heat waves will be more than four times larger than that in the open sea. Moreover, the model allowed us to perform “what-if” scenarios to explore to which extent the flood protection MoSE barriers will modify the lagoon's dynamics. According to the simulations, the number of floods and therefore of the MoSE closure strongly increases with sea level rise. In the most severe scenario, MoSE will have to close for more than 20% of the time in October, November, and December resulting in the reduction of water exchange with the open sea and exacerbation of marine cold spells. Some considerations on the implications of the expected changes on the lagoon's ecology are proposed.

Traditionally, local communities have relied on practical observations accumulated over extended periods to inform their decision-making. This knowledge is now recognized as a viable solution for communities to adapt to climate change effectively. The impact of climate change brings an extra layer of complexity to local communities' detection- and decision-making processes, which needs to be better comprehended.Our study builds on the foundation of conflict resolution and examines the knowledge systems and corresponding decision-making processes of local communities living in urban, rural, and tropical forest regions of Suriname, South America.The mixed-method study showed that the autonomous decision-making processes of these communities are guided by their knowledge systems, intertwined with values and interests. Forest communities in remote locations rely solely on their robust knowledge base for crafting adaptation solutions, while urban and rural communities near the administrative centers develop adaptation strategies primarily considering their access to social networks and relative power.The study highlights local knowledge as the primary determinant for the direction communities take in adaptation, with tradeoffs becoming evident as communities navigate the broader social context. The recognition and integration of this knowledge emerge as a critical factor in enhancing climate change adaptation at the local level.

The water disponibility of Lake Titicaca is important for local ecosystems, domestic water, industry, fishing, agriculture, and tourism in Peru and Bolivia. However, the water level variability in Lake Titicaca (LTWL) still needs to be understood. The fluctuations of LTWL during the 1921–2018 period are investigated using continuous wavelet techniques on high- and low-pass filters of monthly time series, ERA-20C reanalysis, sea surface temperature (SST), and water level. We also built multiple linear regression (MLR) models based on SST indices to identify the main drivers of the LTWL variability. LTWL features annual (12 months), biennial (22–28 months), interannual (80–108 months), decadal (12.75–14.06 years), interdecadal (24.83–26.50 years), and multidecadal (30–65 years) signals. The high- and low-frequency components of the LTWL are triggered by the humidity transport from the lowland toward the Lake Titicaca basin, although different forcings could cause it. The biennial band is associated with SST anomalies over the southeastern tropical Atlantic Ocean that strengthen the Bolivian High-Nordeste Low system. The interannual band is associated with the southern South Atlantic SST anomalies, which modulate the position of the Bolivian High. According to the MLR models, the decadal and interdecadal components of the LTWL can be explained by the linear combination of the decadal and interdecadal variability of the Pacific and Atlantic SST anomalies (r > 0.83, p < 0.05). In contrast, the multidecadal component of the LTWL is driven by the multidecadal component of the North Atlantic SST anomalies (AMO) and the southern South Atlantic SST anomalies. Moreover, the monthly time series of LTWL exhibits four breakpoints. The signs of the first four trends follow the change of phases of the multidecadal component of LTWL, while the fifth trend is zero attributable to the diminished amplitude of the interdecadal component of LTWL.

To effectively monitor and verify carbon dioxide removal through enhanced weathering (EW), this study investigates the use of soil electrical conductivity (EC) and volumetric water content (θ) as proxies for alkalinity and dissolved inorganic carbon (DIC) in soil water. EC-θ sensors offer a cost-effective and straightforward alternative to traditional soil and water sampling methods. In a lab experiment, three different substrates were treated with NaHCO3 solutions to increase the alkalinity of the soil water and analyze the response. The combination of EC and θ to track the increase in carbonate alkalinity due to EW, and therefore CO2 consumption, is applicable for low cation exchange capacity (CEC) soil-substrates like the used quartz sand. However, the presence of organic material and pH-dependent CEC complicates the detection of clear weathering signals in soils. In organic-rich and clay-rich soils, only a high alkalinity addition has created a clear EC signal that could be distinguished from a non-alkaline baseline with purified water. Cation exchange experiments revealed that the used soil buffered alkalinity input and thereby might consume freshly generated alkalinity, initially mitigating CO2 uptake effects from EW application. Effective CEC changes with pH and pH buffering capacity by other pathways need to be considered when quantifying the CO2 sequestration potential by EW in soils. This should be estimated before the application of EW and should be part of the monitoring reporting and verification (MRV) strategy. Once the soil-effective CEC is raised, the weathering process might work differently in the long term.
为了有效监测和验证通过强化风化作用（EW）去除二氧化碳的情况，本研究调查了土壤电导率（EC）和体积含水量（θ）作为土壤水碱度和溶解无机碳（DIC）替代物的使用情况。EC-θ 传感器为传统的土壤和水取样方法提供了一种经济、直接的替代方法。在实验室实验中，用 NaHCO3 溶液处理了三种不同的基质，以增加土壤水的碱度并分析其反应。结合 EC 和 θ 来跟踪 EW 导致的碳酸盐碱度的增加，从而跟踪二氧化碳的消耗，适用于低阳离子交换容量（CEC）的土壤基质，如所用的石英砂。然而，有机物的存在和与 pH 值相关的 CEC 使检测土壤中明确的风化信号变得复杂。在富含有机物和粘土的土壤中，只有添加高碱度后才能产生清晰的导电率信号，并能通过纯水与非碱性基线区分开来。阳离子交换实验表明，使用过的土壤可以缓冲碱度的输入，从而消耗新产生的碱度，初步缓解了施用 EW 所产生的二氧化碳吸收效应。在量化 EW 在土壤中封存二氧化碳的潜力时，需要考虑有效的 CEC 随 pH 值的变化以及其他途径的 pH 缓冲能力。这应在施用 EW 之前进行估算，并应成为监测报告和验证 (MRV) 策略的一部分。一旦土壤有效 CEC 提高，风化过程可能会以不同的方式长期发挥作用。

Numerous dams are currently being built, many of them in transboundary basins. This can lead to disagreements and conflicts between riparian states, compromising not only environmental and social sustainability, but also regional stability and peace. Addressing such conflict risks, states have developed legal and governance mechanisms to address the conflict potential around dams, ranging from international water law principles to dam-specific provisions in basin treaties and from basin management plans to environmental impact assessment approaches. This paper assesses whether, how and to what extent such institutionalized governance mechanisms can prevent or mitigate conflict through both a global perspective (based on global datasets on international water treaties and basin organizations) and a case study perspective (conducting an in-depth analysis of three basins the Mekong, Zambezi, and Senegal river basins). It finds that globally there is a shortcoming in institutionalized cooperation mechanisms preventing and mitigating conflict risks over dams, but in those albeit rather few basins where they do exist, they can reduce conflict risks and thus benefit riparian people, ecosystems, and countries. These findings contribute to the broader discourse on the role of international water law and basin organizations in sustainably managing shared water resources and support calls for the strengthening of those.

Whether and under what conditions scientific knowledge provided by experts actually leads to political action is a question that academic research in various fields have focused on at length, without reaching a definitive answer. The position of expertise is especially delicate within the global environmental governance sphere containing multiple values, worldviews and epistemological standpoints.Firstly, we developed a theoretical model to examine how contextual factors, like institutional design and boundary work dynamics, contribute to expertise influencing global environmental governance. Secondly, we applied this model to the case of the Science Policy Interface to the United Nations Convention to Combat Desertification (UNCCD SPI), using data from semi-structured interviews with SPI stakeholders and participant observation of meetings.We identified specific dimensions of the SPI mandate that enabled expertise to matter: inclusive membership of practitioners, close interaction between experts and political actors, coordination with other advisory bodies, regular reviews, and a small group size. However, after underpinning the prevailing differences in power between SPI experts and member states in their interactions, we found that international environmental decision-making and its national-level implementation remain ultimately and inevitably subordinated to political actors, making it less likely for expertise to have a significant impact.International expertise for sustainable development can only take advantage of the rare “windows of opportunity” that intergovernmental processes concede for experts to influence policy.

In the assessment of climate policies, the social sciences are sometimes assigned a restricted instrumental role, focused on understanding and mitigating social and political “constraints” seen to impede the fullest achievement of a particular technological imaginary. The work presented in this paper draws on an alternative intellectual tradition, in which the technical, social and political dimensions of the problem are seen as closely intertwined, shaped by values and interests specific to each jurisdiction. The Greenhouse Gas Removal Instruments and Policies Project (GRIP), applied this approach to the design of policies for carbon dioxide removal (CDR) in the United Kingdom. GRIP explored what policy incentives and pathways might improve the societal assessment of different CDR technologies for further development and potential deployment. Here we analyze the views of UK policy actors questioned on different CDR options, and outline policy pathways to incentivize the research and demonstration processes necessary to determine what role CDR techniques should play in climate policy. We conclude by discussing recent policy developments in the UK, and the contours of a research agenda capable of supporting a responsible evaluation of CDR options.
