Asian cities will be particularly badly affected. These stripes represent the change in temperature measured in North Carolina from 1895-2019. Many cities around the world are exposed. When averaged over all of the worlds oceans, absolute sea level has risen at an average rate of 0.06 inches per year from 1880 to 2013 (see Figure 1). Coastal cities at risk (CCaR) : building adaptive capacity for managing climate change in coastal megacities. Climate change will affect certain groups more than others, particularly groups located in vulnerable areas and the poor, young, old, or sick. Using the city of Doha as a case study to highlight how sea level rise represents a critical threat to many Arab coastal cities and a national security challenge to Gulf Arab nations, this article underscores the need for greater Many coastal cities have defined minor or nuisance flooding thresholds.

Cities have a unique capability to address climate change. The National Park Service protects natural resources, cultural resources, and facilities in over 120 coastal and parks that are vulnerable to changes in sea and lake levels, saltwater intrusion, ocean acidification, inundation during coastal storms, and the impacts of changing temperature and precipitation regimes. Coastal cities at risk (CCaR) : building adaptive capacity for managing climate change in coastal megacities. This article highlights how the lesser-known issue of sea level rise makes Arab states increasingly vulnerable to climate change. As the pace and extent of coastal flooding and erosion accelerate, climate change impacts along our coasts are exacerbating preexisting social inequities, as communities face difficult questions about determining who will pay for current impacts and future adaptation and mitigation strategies and if, how, or when to relocate. However, coastal and inland cities did not differ in their readiness scores.
