Between 1946 and 1958, the United States conducted nuclear testing in the Pacific Ocean and detonated over 60 atomic bombs in the Marshall Islands. Many of these tests occurred over the Enewetak atoll in the north west of the country, and once they were over, American workers dumped the resulting nuclear waste into a crater that they sealed with concrete in 1979. The Runit Dome, as it is termed, is now leaking. Scientists are concerned that rising sea levels brought about by climate change could inundate the structure, and cause thousands of cubic metres of nuclear waste to flow into the Pacific Ocean.
