Decades after the US buried nuclear waste abroad, climate change could unearth it

A new report says melting ice sheets and rising seas could disturb waste from U.S. nuclear projects in Greenland and the Marshall Islands.
Ariana Tibon was in college at the University of Hawaiʻi in 2017 when she saw the photo online: a black-and-white picture of a man holding a baby. The caption said: “Nelson Anjain getting his baby monitored on March 2, 1954, by an AEC RadSafe team member on Rongelap two days after ʻBravo.’”
Tibon had never seen the man before. But she recognized the name as her great-grandfather’s. At the time, he was living on Rongelap in the Marshall Islands when the U.S. conducted Castle Bravo, the largest of 67 nuclear weapon tests there during the Cold War. The tests displaced and sickened Indigenous people, poisoned fish, upended traditional food practices, and caused cancers and other negative health repercussions that continue to reverberate today.
A federal report by the Government Accountability Office published last month examines what’s left of that nuclear contamination, not only in the Pacific but also in Greenland and Spain. The authors conclude that climate change could disturb nuclear waste left in Greenland and the Marshall Islands. “Rising sea levels could spread contamination in RMI, and conflicting risk assessments cause residents to distrust radiological information from the U.S. Department of Energy,” the report says.
