Climate change is predicted to have an extremely destructive effect on Bangladesh. Natural disasters may take place even more frequently and be greater in magnitude. A rise in sea levels could submerge a considerable proportion of the country. The legal regulations per specific aspects of maritime law are the priority of lawyers as natural risks like rising sea levels, storm surges, or tsunami waves, the pollution of the marine environment all represent a severe threat to coastal inhabitants. Global climate change will thus not only cause environmental degradation but will drive massive social changes as innumerable people migrate from devastated areas. This might further overstretch inadequate infrastructure and governance mechanisms and will lead both to a collapse in living standards and a rise in social disorder. Thus, the article contributes to the expansion of the current regime whereby using the bay water cooling atomic energy plants prevents its use for fish farming purposes, or an oil spill on the high seas pollutes beaches that are essential for tourism within the coastal zone. Such activities destroy our natural climate and change the water level, and promote ocean acidification, ocean stratification, coral bleaching, change species; distributions and make other biological changes to the sea and littoral including the discharge of ballast wastewater which may carry alien invasive species.

Ports constitute a significant influence in the economic activity in coastal areas through operations and infrastructures to facilitate land and maritime transport of cargo. Ports are located in a multi-dimensional environment facing ocean and river hazards. Higher warming scenarios indicate Europe’s ports will be exposed to higher risk due to the increase in extreme sea levels (ESL), a combination of the mean sea level, tide, and storm surge. Located on the west Iberia Peninsula, the Aveiro Port is located in a coastal lagoon exposed to ocean and river flows, contributing to higher flood risk. This study aims to assess the flood extent for Aveiro Port for historical (1979–2005), near future (2026–2045), and far future (2081–2099) periods scenarios considering different return periods (10, 25, and 100-year) for the flood drivers, through numerical simulations of the ESL, wave regime, and riverine flows simultaneously. Spatial maps considering the flood extent and calculated area show that most of the port infrastructures' resilience to flooding is found under the historical period, with some marginal floods. Under climate change impacts, the port flood extent gradually increases for higher return periods, where most of the terminals are at high risk of being flooded for the far-future period, whose contribution is primarily due to mean sea-level rise and storm surges.

AbstractImportant aspects for understanding the effects of climate change on tropical cyclones (TCs) are the frequency of TCs and their tracking patterns. Coastal areas are increasingly threatened by rising sea levels and associated storm surges brought on by TCs. Rice production in Myanmar relies strongly on low-lying coastal areas. This study aims to provide insights into the effects of global warming on TCs and the implications for sustainable development in vulnerable coastal areas in Myanmar. Using TC records from the International Best Track Archive for Climate Stewardship dataset during the 30-year period from 1983 to 2012, a hot spot analysis based on Getis-Ord (Gi*) statistics was conducted to identify the spatiotemporal patterns of TC tracks along the coast of Myanmar. The results revealed notable changes in some areas along the central to southern coasts during the study period. These included a considerable increase in TC tracks (p value < 0.01) near the Ayeyarwady Delta coast, otherwise known as “the rice bowl” of the nation. This finding aligns with trends in published studies and reinforced the observed trends with spatial statistics. With the intensification of TCs due to global warming, such a significant increase in TC experiences near the major rice-producing coastal region raises concerns about future agricultural sustainability.

Security Issues

There is an international consensus that climate change is caused by human activities which substantially increase the atmospheric concentration of greenhouse gases.The ill-effects of climate change are droughts which adversely affect the global poor who are engaged in agriculture; storm surges which destroy local infrastructure, housing and crops; and the rise of sea levels which adversely affect the inhabitants of small island states which could eventually be totally submerged. Military strategists and intelligence analysts are preparing for future conflicts likely to be caused by environmental security issues.The objects of this article are: (i) to evaluate the ill-effects of climate change as a matter of global justice, (ii) to consider whether future generations have the right not to suffer from the ill-effects of climate change, and if so, (iii) to evaluate the relevant conceptions of global justice, and (iv) to assess critically whether international law provides effective preventive responses to climate change and environmental security threats.Finally, a monist-naturalist conception of global justice privileging human dignity as one of its guiding principles is proffered as a solution to the problems raised by the mechanisms of dealing with the ill-effects of climate change and the attendant environmental security issues under international law.

The Past

The vertical telescopic breakwater(VTB), which is a new breakwater that permits the navigation of ships, remain at the bottom of the sea during calm and rise to the surface during tsunamis or storm surges. Kawai et al. (2017) and Arikawa et al. (2019) found that it is effective not only for swell waves, but also for long-period waves simulating tsunamis and storm surges by previous experiments and numerical analyses. However, there have been few studies on the performance of VTB by numerical calculations in actual ports using actual typhoons. In addition, sea levels and changes in characteristics of typhoon due to climate change are predicted to occur; hence, we are concerned about the damage in all quarters caused by storm surge inundation, especially at Tokyo. Therefore, in this study, we used hypothetical typhoons under worst-case scenarios and quantitatively evaluated the protection performance of VTB against hypothetical typhoons with different aperture rates of VTB in Tokyo Bay by the numerical simulation.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/qof5ixKqIiA

Abstract Higgason, K. D., and Brown, M. 2009. Local solutions to manage the effects of global climate change on a marine ecosystem: a process guide for marine resource managers. – ICES Journal of Marine Science, 66: 1640–1646. The marine environment plays an important role in controlling the amount of CO2 that remains within the earth’s atmosphere, but it has not received as much attention as the terrestrial environment regarding climate-change effects, mitigation programmes, and action plans. Potential physical effects of climate change within the marine environment, including ocean acidification, changes in winds that drive upwelling and ocean circulation patterns, increasing global sea surface temperatures, and sea level rise, can result in dramatic changes within marine and coastal ecosystems. Often, marine resource managers feel overwhelmed by the magnitude of this issue and are therefore uncertain how to begin to take action. It may seem that they do not have the time, funding, or staff to take on a challenge as large as climate change, and fail to act as a result. Using NOAA’s Gulf of the Farallones National Marine Sanctuary as a case study, this paper outlines the need to act now and presents an easy-to-use process guide, providing managers options to incorporate effectively the influences of climate change into management strategies, as well as mitigate these influences through community outreach and a reduction in workplace emissions.
