NASA Analysis Shows Irreversible Sea Level Rise for Pacific Islands

Climate change is rapidly reshaping a region of the world that’s home to millions of people.

Climate change is rapidly reshaping a region of the world that’s home to millions of people.

In the next 30 years, Pacific Island nations such as Tuvalu, Kiribati, and Fiji will experience at least 6 inches (15 centimeters) of sea level rise, according to an analysis by NASA’s sea level change science team. This amount of rise will occur regardless of whether greenhouse gas emissions change in the coming years.

The sea level change team undertook the analysis of this region at the request of several Pacific Island nations, including Tuvalu and Kiribati, and in close coordination with the U.S. Department of State.

In addition to the overall analysis, the agency’s sea level team produced high-resolution maps showing which areas of different Pacific Island nations will be vulnerable to high-tide flooding — otherwise known as nuisance flooding or sunny day flooding — by the 2050s. Released on Sept. 23, the maps outline flooding potential in a range of emissions scenarios, from best-case to business-as-usual to worst-case.
