Summary: Modeling suggests that coastal regions will experience rapid erosion due to climate-change-induced sea level rise. However, earthquakes can also contribute to coastal cliff retreat, and this factor is often overlooked in forecasting models. This study focuses on the contribution of earthquakes to multidecadal coastal cliff retreat and finds that large earthquake-induced landslide-triggering events significantly contribute to cliff-top retreat rates. The findings highlight the underestimation of true retreat rates in seismically active regions when relying solely on historical records to predict cliff-top retreat.

Summary: The response of coastal barrier islands to relative sea-level rise (SLR) has long been debated. This study finds that while the rate of SLR along the USA East Coast has increased by over 200% in the last 100 years, the retreat rate of barrier islands has only increased by about 45%. It is shown that the modern retreat rate is not controlled by recent SLR but rather by the baseline SLR of the past centuries.

Summary: Erosion plays a crucial role in the activity of coastal landslides. Quantitative characterization of the feedbacks between erosion and landslide advance is essential, suggesting an inversely proportional relationship between landslide volume and magnitude of advance. Additionally, landslide geometry has a secondary control on the sensitivity of advance to coastal erosion.

Summary: For too long, implicit acceptance and assumptions about colonial property rights have guided adaptation policy pathways. The challenges posed by private property rights for effective adaptation planning are increasingly recognized, but there is yet to be sustained and systematic attention to how property rights entrench maladaptive tendencies.

Summary: Airborne LiDAR datasets were used to measure erosion and retreat along 866 km of California coastal cliffs between 2009-2011 and 2016. The results showed that erosion exceeding the level of detection was observed at 55% of cliffs, with more erosion in northern California compared to southern and central California. Retreat rates were higher for unarmored cliffs and cliffs fronted by sandy beaches. The average cliff top retreat rates were lower than in previous studies, but the average cliff face retreat rates were similar for different time periods.

Summary: The vulnerability of coastal wetlands to sea level rise is influenced by processes of vertical accretion and landward migration. Wetlands respond to these factors by trapping sediments and migrating to more preferred inundation conditions, with their responses depending on water flow and sediment distribution within the wetland. Neglecting these factors in wetland response analysis can lead to inaccurate estimates of wetland resilience.

Summary: Shoreline erosion in Point Hope, Alaska, USA has caused significant loss of tundra behind the beach. Analysis of data suggests that local beach slopes and wave runup are important factors influencing tundra retreat. The erosion rates primarily depend on local beach erosion and tidal waves. Future changes in sea level and wave energy are expected to further accelerate tundra erosion.

Summary: Thermodenudation on the Kara seacoast of the Yugorsky Peninsula, Russia, was studied through analyzing remote-sensing data. The formation of thermocirques, resulting from the thaw of tabular ground ice due to polycyclic retrogressive thaw slumps, was monitored over the last decade (2010-2020). The retreat rates of thermocirques were found to have very low correlation with summer warmth, rainfall, and wave action.

Summary: The study finds that Indigenous communities have autonomously implemented a generational retreat strategy to respond to coastal hazard risks, drawing on local resources and processes to adapt to local sociopolitical, cultural, and environmental contexts. This locally conceived and driven retreat form provides an adaptive and sustainable response to coastal change.

Summary: Despite the widespread promotion and international investment in livelihood diversification projects, the outcomes in terms of improved resource management and rural development are inconsistent. This can be attributed to a lack of understanding of the complexity of livelihood diversification. Therefore, utilizing a diversity framework can help clarify this ambiguity.

Summary: Climate change has led to various hazards affecting coastal areas and communities, resulting in increased displacement of people. Managed retreat, as an adaptation strategy, has faced challenges such as social impacts and top-down planning. To address these challenges, a co-production approach is suggested, which involves incorporating local knowledge, establishing connections between local knowledge and institutional mechanisms, and facilitating community-led processes of retreat and redevelopment to achieve a more environmentally just approach to managed retreat.

Summary: Sea-level rise and coastal flooding have significant impacts on residents' daily lives. Understanding who will be affected and when is crucial for inclusive and cost-effective adaptation planning. This study evaluates the effects of sea-level rise on residents' access to key amenities and finds that accessibility loss may occur before parcel inundation, indicating a need for earlier retreat. The study also highlights the importance of consensus on future planning scenarios.

Summary: High and accelerated sea-level rise due to Antarctic ice sheet instability and retreat in this century poses challenges for coastal investment planning in densely populated coastal zones like the Netherlands. New technologies, experiments, strategies, and governance are needed to address this challenge. Strategic choices, such as closing estuaries, managing high river discharges, and adapting agriculture to saline coastal areas, along with no-regret measures, are essential for long-term adaptation to high sea-level rise.

However, there may be adaptation limits by the end of this century, indicating the need for further greenhouse gas emissions mitigation.

Summary: Sea level rise is a long-lasting consequence of climate change, and despite uncertainties, climate model-based projections are used to support decision-making. A community effort has been made to quantify high-end global sea level rise, providing additional information on potential future scenarios. The timing of ice shelf collapse in Antarctica is emphasized as a critical factor for sea level rise.

Summary: Sea-level rise increases the likelihood of exceeding local protection infrastructure, and the authors propose a method to determine when the degree of local protection decreases. This study projects the timing of extreme sea level frequency amplification relative to estimated local flood protection standards. Results show that within the next 30 years, the frequency of exceeding protection standards will significantly increase at a high proportion of tide gauges under different emissions scenarios.

Summary: The state of global coastal adaptation is currently halfway towards its full potential, with urban areas generally scoring higher than rural areas. Efforts in adaptation are unbalanced across different dimensions and strategizing for long-term pathways is limited. This assessment provides a multi-dimensional and locally grounded perspective on global coastal adaptation, highlighting the need to refine global adaptation targets and identify priorities transcending development levels.

Summary: Reducing the risk of maladaptation is crucial for successful climate adaptation. The authors propose a framework, Navigating the Adaptation-Maladaptation continuum (NAM), to assess adaptation outcomes. The NAM framework includes criteria related to ecological, climate, and social outcomes, as well as equity-related outcomes for disadvantaged groups. By applying the framework to different adaptation options, variations in potential adaptation and risk of maladaptation are identified. Decision-makers are encouraged to prioritize responses that minimize the risk of maladaptation based on the NAM framework.

Summary: The study introduces a stepwise approach for identification of socio-economic tipping points (SETPs), which can support decision making under uncertain climate and socio-economic conditions. Through a stylized case study on the collapse of house prices in a coastal city due to increasing flood risk, the research finds that proactive strategies and rapid implementation of flood protection measures are necessary to avoid tipping points in real estate prices under scenarios with high and rapid sea level rise.
