Summary: This study investigates the flood mitigation capabilities of coastal wetlands by simulating wetland features and storm characteristics. The results show that the tidal channel area and storm scales have non-linear effects on peak water level attenuation. A multivariate scaling relationship is proposed to integrate the combined impacts of wetland geometry and storm scales on water level attenuation.

Summary: Tropical aquatic ecosystems are impacted by warming, leading to a decrease in connectivity between terrestrial and aquatic habitats, as well as a reduction in the flux of aquatic resources to terrestrial ecosystems and variable effects on the breakdown of terrestrial resources in aquatic ecosystems. This could potentially impact consumers in both ecosystem types and disrupt cross-ecosystem dynamics in an interconnected tropical landscape.

Summary: The study found that levee openings in coastal Louisiana have limited impact on reducing storm surge in adjacent basins, mainly due to complex interactions between the surge and the flow of the Mississippi River. The openings were not effective in reducing storm surge during Hurricane Isaac due to diversion of river water into adjacent basins, essentially defeating their intended purpose.

Summary: Despite overall warming, many regions in the Northern Hemisphere have been cooling in autumn. This cooling has led to an increase in the release of net CO2, as primary production decreased more than respiration in cooling areas and respiration increased more than production in warming areas. Despite opposite temperature trends, there has been a systematic increase in ecosystem carbon release across the Northern Hemisphere middle and high latitudes.

Summary: This study provides a consistent estimation of projected changes in global storm surges and ocean waves, showing that the trend in annual maximum sea surface heights and wave heights is predominantly driven by changes in tropical cyclone frequency. Future projections suggest a decrease in tropical cyclone frequencies in the western North Pacific, leading to decreasing trends in annual maximum sea surface heights and wave heights.

Summary: The ability of plants to respond to environmental fluctuations is achieved through adaptive adjustments in plant form and function. While land plants require extensive acclimation to light and temperature variations, floating aquatic plants like duckweed are less dependent on acclimation and can thrive in different light conditions. This is due to their high growth rates, photosynthetic capacities, and ability to produce photoprotective compounds without compromising efficiency. This contrast highlights the importance of land plants experiencing light fluctuations before inducing acclimatory adjustments.

Summary: The vulnerability to coastal disasters resulting from storm surges and wave overtopping is increasing due to rising sea levels. This study used a unified modeling system to simulate the vulnerability to wave overtopping in the Northwest Pacific Ocean. The results showed that vulnerability to wave overtopping intensifies with rising sea levels. The integrated model can be used for long-term coastal protection design and short-term storm surge early warning systems.

Summary: Nature-based solutions, specifically managed realignment (MR), are suggested for mitigating coastal flood risks. However, MR projects often face opposition from local communities due to concerns about returning land to the sea and skepticism about their coastal protection capabilities. It is crucial to improve the scientific knowledge base and involve local communities and stakeholders in decision-making to optimize the success of coastal nature-based solutions and gain community acceptance.

Summary: In this study, the authors used a high-resolution typhoon model to simulate and analyze 49 typhoons that made landfall in Japan between 2000 and 2017. The study revealed an increasing trend in typhoon intensity under future climatic conditions, both at peak and landfall times. Furthermore, the degree of change in typhoon intensity was found to be influenced by the elapsed time from genesis to landfall and the radius of maximum wind speed at landfall. By establishing statistical formulas, future changes in central pressure and radius of maximum wind speed can be predicted, providing guidance for disaster prevention and mitigation measures in coastal regions and ports.

Summary: The sedimentation rate in tidal marshes increases with water depth, and elevation is negatively correlated with accretion rate while positively correlated with total organic carbon content. Spatial patterns of cross-sectional morphology in wetlands conform to typical forms in estuarine areas, but differ in riverine reaches. Channel perimeter and surface area exhibit high variability between estuarine and riverine reaches.

Summary: A recent report from the National Academies addresses the cumulative effects of large-scale restoration projects and the challenges in monitoring and assessing these effects in the context of long-term environmental change. The report highlights gaps in data collection, data accessibility issues, and the lack of synthesis and analysis as obstacles to understanding the impacts of restoration efforts on ecosystem health and productivity in the Gulf of Mexico. The proposed approach includes using emerging monitoring technologies, devising an adaptive management framework, reassessing restoration goals, and conducting rigorous synthesis and analysis to overcome these challenges and achieve large-scale environmental recovery.

Summary: Subsidence caused by subduction zone earthquakes can significantly impact estuarine bathymetry. Through using a hydrodynamic and habitat model, we quantified the effects of earthquake-induced subsidence on hydrodynamics and habitat distributions in the lower Columbia River Estuary, a major system. The model results show that coseismic subsidence increases tidal range, with the largest increase occurring in areas of topographic convergence. Intertidal habitat is reduced by 24%-25% in all scenarios, and about 93% of estuarine wetlands are shifted to lower-elevation habitat bands. Considering the dynamic effects of tidal changes from subsidence leads to higher estimates of remaining habitat, depending on the habitat type.

Summary: This study examines the changes in water temperatures in the lower Columbia River by analyzing historical temperature measurements since the 1850s. The results show an increase in annual averaged water temperature by 2.2℃ since the 1850s, with a rate of 1.3℃/century. The increase in water temperature is primarily driven by warming air temperatures (29%), altered river flow (14%), and water resources management (57%).

Summary: Using archival research methods, this study developed a statistical regression model to analyze the changes in water temperature in the lower Willamette River over a 140-year period. The results showed a consistent increase in temperature, with the largest shift occurring in winter months. The duration of high temperatures and the decrease in cold-water days have also been observed. These changes are primarily attributed to increases in air temperature and alterations in the river system.
