Whether the world is prepared for it or not, climate change will drive large-scale migration. The impacts of climate change—both slow-onset changes, such as sea-level rise and drought, and sudden-onset events, such as extreme storms and wildfires—push people from their homes. Managed well, migration can yield enormous benefits, offering greater opportunities for those who relocate and injecting new talent and energy into receiver communities. But climate change threatens to unleash “disruptive migration,” that is, sudden migration that could strain social, economic, and political stability. The task ahead in the face of climate change is to encourage managed, gradual migration that minimizes disruption, moves people out of harm’s way, and turns displacement into economic opportunity. This chapter outlines the strategies and tools that exist to make this possible.

"Dwelling" basically means living in a place. However, Dwelling itself has a broader meaning when we understand how humans decided to inhabit. In the book The Nature of Order, Christopher Alexander says "Dwelling is Living-Structure" which means to live is a life participating in a living-structure. This quote directly describes a relationship between nature and humans in the process of living. Seeing the conditions that exist in the world today, there are many aspects that can affect the way humans will live in the future. One of the problems that humans have to face is climate change which causes sea level rise. Realizing that humans must face these events and know that in reality, humans cannot be separated from their natural surroundings, "The Dynamic of Adaptive Shelter" was designed with the aim of wanting to unite aspects of habitation (especially nature and humans) as well as provide solutions for buildings that are adaptive to sea level rise. Located in Kamal Muara, North Jakarta, this project begins by studying the selected site, community activities, the shape of the buildings around the site, as well as the natural characteristics around the site, as a method that refers to a quote from Martin Heidegger's book about "the thing It-self". Referring to the results of the selected site, this project is complemented with programs that are suitable for the activities of the residents of the area and have been developed with systems which can adapt to the issue of sea level rise. Keywords:  Adaptive-Dynamic; Coastal; Dwelling; Fishermen ; Sea Level Rise Abstrak“Dwelling” atau Berhuni pada dasarnya memiliki arti hidup pada suatu tempat. Namun Dwelling sendiri memiliki arti yang lebih luas saat kita memahami awal mula manusia memutuskan untuk berhuni. Dalam buku The Nature of Order Christohper Alexander mengatakan “Dwelling is Living- Structure” yang berarti berhuni adalah hidup berpartisipasi dalam Struktur-kehidupan (Living- structure). Kutipan tersebut secara langsung menggambarkan sebuah keterkaitan antara alam dan manusia dalam menuju proses berhuni. Melihat kondisi yang ada didunia saat ini banyak aspek yang dapat mempengaruhi cara manusia berhuni dimasa depan. Salah satu permasalahan yang harus dihadapi manusia adalah perubahan iklim yang menyebabkan kenaikan permukaan air laut. Menyadari bahwa manusia harus menghadapi peristiwa tersebut dan mengetahuni bahwa pada dasarnya dalam proses berhuni manusia tidak terlepas dari alam sekitarnya, “Wadah Adaptif- Dinamis” dirancang dengan tujuan ingin mempersatukan aspek-aspek berhuni (khususnya alam dan manusia) dan juga memberikan solusi akan bangunan yang adaptif akan kenaikan permukaan air laut. Berlokasi di Kamal Muara, Jakarta Utara proyek ini diawali dengan mempelajari site terpilih, aktivitas masyarakat, bentuk bangunan sekitar tapak, dan juga karakteristik alam sekitar tapak, sebagaimana metode yang mengacu pada kutipan buku Martin Heidegger tentang “the thing It-self”. Mengacu pada hasil analisis tapak terpilih, proyek ini dilengkapi dengan program-program yang sesuai dengan aktifitas penduduk daerahnya dan telah dikembangkan dengan sistem-sistem yang mana dapat beradaptasi dengan kondisi alam sekitar dan menjawa isu akan kenaikan permukaan air laut.

This chapter discusses what constitutes adaptation responses by firms in the face of climate change. There are four integral components of adaptation activities undertaken by firms: assessment of risk, understanding of vulnerability, understanding the regulatory barriers to overcome the vulnerability, and, finally, adoption of policies to overcome the vulnerability. While it is easy to understand these components separately, their interdependencies make the overall picture more complicated. Also complicating the issue is the fact that most small and medium firms do not have the capacity and resources to predict the impact of such changes on their operations, and hence, to quickly make the adjustments necessary to overcome them. The response of firms also depends on the nature of the climate risk they face, whether it is sea-level rise, or temperature rise.

AbstractCoastal wetlands are large reservoirs of soil carbon (C). However, the annual C accumulation rates contributing to the C storage in these systems have yet to be spatially estimated on a large scale. We synthesized C accumulation rate (CAR) in tidal wetlands of the conterminous United States (US), upscaled the CAR to national scale, and predicted trends based on climate change scenarios. Here, we show that the mean CAR is 161.8 ± 6 g Cm−2 yr−1, and the conterminous US tidal wetlands sequestrate 4.2–5.0 Tg C yr−1. Relative sea level rise (RSLR) largely regulates the CAR. The tidal wetland CAR is projected to increase in this century and continue their C sequestration capacity in all climate change scenarios, suggesting a strong resilience to sea level rise. These results serve as a baseline assessment of C accumulation in tidal wetlands of US, and indicate a significant C sink throughout this century.

The Maldives, with one of the lowest average land elevations above present-day mean sea level, is among the world regions that will be the most impacted by mean sea-level rise and marine extreme events induced by climate change. Yet, the lack of regional and local information on marine drivers is a major drawback that coastal decision-makers face to anticipate the impacts of climate change along the Maldivian coastlines. In this study we focus on wind-waves, the main driver of extremes causing coastal flooding in the region. We dynamically downscale large-scale fields from global wave models, providing a valuable source of climate information along the coastlines with spatial resolution down to 500 m. This dataset serves to characterise the wave climate around the Maldives, with applications in regional development and land reclamation, and is also an essential input for local flood hazard modelling. We illustrate this with a case study of HA Hoarafushi, an atoll island where local topo-bathymetry is available. This island is exposed to the highest incoming waves in the archipelago and recently saw development of an airport island on its reef via land reclamation. Regional waves are propagated toward the shoreline using a phase-resolving model and coastal inundation is simulated under different mean sea-level rise conditions of up to 1 m above present-day mean sea level. The results are represented as risk maps with different hazard levels gathering inundation depth and speed, providing a clear evidence of the impacts of the sea level rise combined with extreme wave events.

It is essential to monitor accurately current sea level changes to better understand and project future sea level rise (SLR). This is the basis to support the design of adaptation strategies to climate change. Altimeter sea level products are operationally produced and distributed by the E.U. Copernicus services dedicated to the marine environment (CMEMS) and climate change (C3S). The present article is a review paper that intends to explain why and to which extent the sea level monitoring indicators derived from these products are appropriate to develop adaptation strategies to SLR. We first present the main key scientific questions and challenges related to SLR monitoring. The different processing steps of the altimeter production system are presented including those ensuring the quality and the stability of the sea level record (starting in 1993). Due to the numerous altimeter algorithms required for the production, it is complex to ensure both the retrieval of high-resolution mesoscale signals and the stability of the large-scale wavelengths. This has led to the operational production of two different sea level datasets whose specificities are characterized. We present the corresponding indicators: the global mean sea level (GMSL) evolution and the regional map of sea level trends, with their respective uncertainties. We discuss how these products and associated indicators support adaptation to SLR, and we illustrate with an example of downstream application. The remaining gaps are analyzed and recommendations for the future are provided.

Tidal inundation, flood and land subsidence are the problems faced by Semarang city related to climate change. Intergovernmental Panel on Climate Change (IPCC) predicted the increase of sea level rise 18-59 cm during 1990-2100 while the temperature increase 0,6°C to 4°C during the same period. The Semarang coastal city was highly vulnerable to sea level rise and it increased with two factors, topography and land subsidence. The purpose of this study was to map the adaptive capacity of coastal areas in the face of the threat of disasters caused by climate change. The parameters used are Network Number, Employee based educational background, Source Main Livelihoods, Health Facilities, and Infrastructure Road. Adaptive capacity of regions classified into 3 (three) classes, namely low, medium and high. The results of the study showed that most of the coastal area of Semarang have adaptive capacities ranging from low to moderate, while the village with low capacity totaling 58 villages (58.62%) of the total coastal district in the city of Semarang.

Abstract. Nearshore slope, defined as the cross-shore gradient of the subaqueous profile, is an important input parameter which affects hydrodynamic and morphological coastal processes. It is used in both local and large-scale coastal investigations. However, due to unavailability of data, most studies, especially those that focus on continental or global scales, have historically adopted a uniform nearshore slope. This simplifying assumption could however have far reaching implications for predictions/projections thus obtained. Here, we present the first global dataset of nearshore slopes with a resolution of 1 km at almost 620,000 points along the global coastline. To this end, coastal profiles were constructed using global topo-bathymetric datasets. The results show that the nearshore slopes vary substantially around the world. An assessment of sea level rise (SLR) driven coastline recession (for an arbitrary 0.5 m SLR) with a globally uniform coastal slope of 1:100, as done in previous studies, and with the spatially variable coastal slopes computed herein shows that, on average, the former approach would under-estimate coastline recession by about 40 %, albeit with significant spatial variation. The final dataset has been made publicly available at https://doi.org/10.4121/uuid:a8297dcd-c34e-4e6d-bf66-9fb8913d983d.

The Race to Zero is the largest credible alliance aiming to reduce twice emissions by 2030, with the main goal of moving towards a carbon-zero economy by 2050. Zero emission technologies can reduce the greenhouse gas concentrations in Atmosphere that can help to slowdown the Global Warming but for making the Earth’s climate system more stable we need implement Negative emission technologies. Negative emission technologies can significantly reduce the greenhouse gas concentrations in Atmosphere that can getting down the global average temperature to the pre-industrial level and prevent Global Warming and future Sea Level Rise. The currently observed climatic changes cannot be completely explained by the increase in the concentration of carbon dioxide in the atmosphere. Taking into account the impact of methane emissions, including the Polar Regions and the World Ocean, it will be possible to explain rapid changes in the Earth's climate. For getting the Earth’s climate system stable and predictable we need to reduce greenhouse gas concentrations in the atmosphere and the global average temperature to the pre-industrial levels. If this aims cannot be achieved then Climate Change and associated with Global Warming future Sea Level Rise in the nearest future would be the most important Risk factors in the Global World and World Economy, that can provide the world massive losses and economic crisis.

<p>Climate change is widely regarded as the leading global issue of the 21st century. There is now a general international agreement, supported by an overwhelming amount of scientific evidence, that the global climate is changing at an accelerated rate and that human-driven emissions of greenhouse gases into the atmosphere is the main factor driving this trend. Arguably the most devastating impact of climate change on the human civilisation will be a rapidly increasing rise in global sea levels, which are currently rising at an unprecedented rate, placing hundreds of millions of people at serious risk of inundation in coastal communities across the globe. In the case of New Zealand’s capital city, Wellington, over ten percent of the city’s residents are at risk of displacement by the end of this century. This thesis aims to find a solution to resident displacement in the coastal city, addressing the question, How can a resilient residential dwelling be designed for the coastal city, in response to the encroaching pressures of climate change driven sea level rise? This research question and its subsequent design aims have been achieved through a highly iterative design process resulting the development of a connected network of amphibious dwelling solutions which provide the residents of the selected focus community of Kilbirnie, a coastal suburb in Wellington city, with the capacity to accommodate, adapt and thrive in the face of sea inundation. Hereby ensuring the social sustainability of the coastal community, currently at serious risk of displacement as a direct result of climate change driven sea level rise.</p>
