Indicative areas that will require risk analysis to establish their likely vulnerability to coastal inundation as a result of sea-level rise – either directly (eg, inundation during storm events) or by the impact of sea-level rise on the drainage of low-lying coastal lands. The shaded red and orange areas show approximate land levels less than 5 m and 10 m above sea level, respectively: they have been extracted from reprocessed topography data collected by the Space Shuttle Radar Topography Mission (NASA). Accuracy of the topography is around 5–8 m. Credit: Ministry for the Environment 2008
