NASA tool shows how rising sea levels will affect New York, London, other coastal cities

Small iceberg in an ice fjord is seen in southern Greenland. Sea levels are projected to rise by between one and four feet around the world by 2100.

A new tool developed by NASA scientists can pinpoint which glaciers and ice sheets are contributing to changing sea levels in almost 300 coastal cities.

The Gradient Fingerprint Mapping Simulation allows users to spin a virtual globe and select one of hundreds of coastal cities, which will then produce a small blurb about how much sea levels are projected to rise in the area and the name of the contributing glacier.

NASA launches a new tool that reveals projected sea level rise by coastal city.

The accompanying study analyzes 293 major port cities and aims to let coastal planners accurately calculate local sea level changes as well as know which melting parts of the Earth’s polar ice cap present the biggest risks to each region.

“This study allows one person to understand which icy areas of the world will contribute most significantly to sea level change [rise or decrease] in their specific city,” Eric Larour, the project lead for NASA JPL’s Ice Sheet System Model (ISSM) and lead author of the study, told CNN.
