Halfway between Hawaii and Australia, smack dab in the Pacific Ocean, is the Kwajalein Atoll, part of the Marshall Islands. It’s home to one of the U.S. military’s most crucial bases and infrastructure: the Ronald Reagan Ballistic Missile Defense Test Site

This base has been critical to the United States since World War II, but now it’s under threat from climate change. Sea levels are rising faster in this part of the Pacific than anywhere else in the world. One study, led by the U.S. Geological Survey, suggests that islands in the Kwajalein Atoll could be uninhabitable by the middle of this century.

This will be devastating to the nearly 40,000 people who call the Marshall Islands home. As sea levels continue to rise, salt water intrusion means some islands will lose fresh water supplies and all drinking water will need to be shipped in. 

How will our military respond to this existential threat? And what do rich countries and major carbon emitters like the U.S. owe the people and nations bearing the brunt of the climate crisis? In this episode, host Kai Ryssdal spends time on these remote, tropical islands.
