Detailed
impacts, however, will vary strongly from region to region and coast to coast and therefore can not be easily
generalized, as
changing mean and extreme coastal water levels depend on a combination
of near shore and offshore processes, related to climatic but also non-climatic anthropogenic factors, such as natural land movement arising from tectonics, volcanism or compaction; land subsidence due to anthropogenic extraction
of underground resources; and
changes in coastal morphology resulting from sediment transport induced by natural and / or anthropogenic factors.
• Improved understanding
of climate thresholds and vulnerabilities,
impacts, and adaptive responses in a variety
of different local contexts across the country • Improved understanding
of vulnerable populations (e.g., urban poor, native populations on tribal lands) that have limited capacities for responding to climate
change • Ways to build adaptive capacity that can be
generalized across individuals, communities, and countries • Decision support tools for entities responsible for hazard mitigation and management • Collection
of socioeconomic research to inform
impact, vulnerability, and adaptation research
