Global survey shows planners use widely varying sea-level rise projections for coastal adaptation

Uneven distribution of the application of sea-level science

We gained important insights at the global, continental, regional, and country scales about whether and to what degree coastal managers are using SLR projections in their coastal planning. Working closely with partners and using a snowball sampling approach⁴² 253 coastal managers completed our questionnaire. This sample represents the first global data collection on SLR use in decision making⁴³ (Supplementary Table 1, Supplementary Table 2 and Supplementary Fig. 1). Our respondents all identified as planners working primarily…
