Summary: The Earth's changing climate is causing ice sheets and glaciers to melt, leading to rising coastal hazards and sea levels. Coastal areas with a total population of over 300 million people, including 20 megacities, are among the most vulnerable to climate change impacts. Sea-level rise, combined with other factors, could lead to the displacement of hundreds of millions of people, with significant global impacts.

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: Carbon sequestration and storage in coastal ecosystems such as mangroves, salt marshes and seagrass meadows play a significant role in climate change mitigation, contributing nearly $200 billion annually to global blue carbon wealth. By utilizing a country-specific social cost of carbon, it is possible to calculate each country's contribution to and redistribution of global blue carbon wealth, with countries like Australia, Indonesia and Cuba generating the largest positive net benefits for the rest of the world through coastal ecosystem carbon sequestration and storage.

Summary: This study provides a comparative assessment of uncertainties and biases in global to world-regional scale assessments of coastal flood risks, identifying human adaptation as the largest bias contributing to potential overestimation of coastal flood risk in 2100. Even with adaptation considered, uncertainties in how societies will respond to sea-level rise dominate all other uncertainties. Quantified global uncertainties include socio-economic development, digital elevation data, ice sheet models, and greenhouse gas emissions.

Summary: Land subsidence is causing relative sea-level rise and impacting coastal populations in Asia, particularly in China. This study assesses the risks and suggests response strategies. It finds that people are concentrated in subsiding areas, leading to higher sea-level rise rates compared to climate-induced rise. If the current subsidence rates continue, the areas, population, and assets exposed to coastal flooding by 2050 will be significantly higher than those caused by climate change alone. Realistic subsidence control measures can mitigate a large portion of the additional risks, but adaptation measures are still needed to address the remaining risks.

Summary: Climate change-induced sea-level rise will lead to increased internal migration, with the intensity and spatial patterns depending on the amount of sea-level rise, future socioeconomic development, and adaptation strategies. Using a spatially-explicit model, researchers found that without adaptation policies, there could be up to 20 million sea-level rise-related internal migrants in the Mediterranean region by 2100, with higher migration in southern and eastern countries. However, adaptation policies can reduce the number of migrants by a factor of 1.4 to 9, with different effects depending on the strategies pursued.
