While it’s unknown by exactly how much, sea levels are expected to rise during this century, thanks to climate change.
The U.N.’s Intergovernmental Panel on Climate Change (IPCC) estimates the sea level could rise by as much as , or just over 3 feet.
The IPCC came up with this estimate based on an emissions scenario of RCP 8.5 (RCP stands for representative concentration pathway), which models based on what will happen if emissions continue to rise in their current trajectory—the scenario. And this IPCC estimate does not take ice sheet melting into account, which some studies suggest could make the sea-level rise even greater.
Even with an aggressive global reduction of carbon emissions, some scenarios still predict a sea-level rise of a 0.5 metre. If either of these scenarios come to pass, it will have numerous and grave consequences for communities and infrastructure around the world.
Resource Watch, a research platform run by the World Resources Institute, conducted a study in February 2020 to analyze how this sea-level rise would impact one type of infrastructure in particular: .
It did this by taking on how sea level rises of both 0.5 metre and 1 metre would impact different parts of the world. They then combined that data with altitude, elevation, and geographic data from . This gave it a list of 80 airports threatened by rising sea levels. Out of these 80 airports, 44 will be impacted with a sea-level rise of just a 0.5 metre. The other 36 won’t be under threat until sea level reaches 1 metre or more.
chose 30 of the 80 airports highlighted by the Resource Watch study. Some of these airports are big, like Amsterdam’s Schiphol Airport, the 11th busiest in the world.
Some are small, like Edward Bodden Airfield, located on Little Cayman Island. Many are located on islands, which are naturally vulnerable to sea-level rise.
Three of these airports are in the Netherlands, a country with a significant amount of land below sea level. A number are located in China. Many others are situated on island nations, which are already struggling with the impacts of climate change. Some are naval airports.
What they all have in common is that by 2100, they may no longer exist.

(AMS) is the 11th busiest airport in the world, with more than 71 million travellers flying in or out or transferring through it in 2019. (Numbers dropped precipitously in 2020 due to the pandemic). With just a 0.5 metre of sea-level rise, it could be flooded by the North Sea. However, this does not take into account flood prevention strategies, and the Netherlands is one of the world leaders in water management.
