Sea-Level Rise and Its Impact on Coastal Zones

TLDR

Global sea‑level rise has accelerated in the 20th century and is projected to continue into the 21st century, but its magnitude is uncertain due to factors such as Greenland and West Antarctic ice sheets, regional variability, and local subsidence. The study seeks to evaluate the uncertainties surrounding the impacts of sea‑level rise and the effectiveness of adaptation measures.

Abstract

Global sea levels have risen through the 20th century. These rises will almost certainly accelerate through the 21st century and beyond because of global warming, but their magnitude remains uncertain. Key uncertainties include the possible role of the Greenland and West Antarctic ice sheets and the amplitude of regional changes in sea level. In many areas, nonclimatic components of relative sea-level change (mainly subsidence) can also be locally appreciable. Although the impacts of sea-level rise are potentially large, the application and success of adaptation are large uncertainties that require more assessment and consideration.
