Figures & data

Figure 1. Storyline framework – Discrete storylines within a continuum of future system states. The grey and black line indicate possible storylines, which connect the choices in the remote climate drivers to sea level rise, the choices in infrastructure adaptation and the choices in infrastructure expansion. Individual choices can be made with regards to adaptation and expansion for different infrastructure types.

Flooded areas are indicated in shades of blue, according to the water depth. Right panel: The spatial distribution of locations that suffer damages to CI along the coastline of Western France.
