Atomic racism decimated Kiribati and the Marshall Islands; now climate change is sinking them
This is an extract from the Don’t Bank on the Bomb Scotland report “Nuclear Weapons, the Climate and Our Environment”.
Kiribati
In 1954, the government of Winston Churchill decided that the UK needed to develop a hydrogen bomb (a more sophisticated and destructive type of nuclear weapon). The US and Russia had already developed an H-bomb and Churchill argued that the UK “could not expect to maintain our influence as a world power unless we possessed the most up-to-date nuclear weapons”.
The governments of Australia and New Zealand refused to allow a hydrogen bomb test to be conducted on their territories so the British government searched for an alternative site. Kiritimati Island and Malden Island in the British Gilbert and Ellice Islands Colony in the central Pacific Ocean (now the Republic of Kiribati) were chosen. Nine nuclear weapons tests – including the first hydrogen bomb tests – were carried out there as part of “Operation Grapple” between 1957 and 1958.

After Grapple X, the UK’s first megaton hydrogen bomb test in November 1957, dead fish washed ashore and “birds were observed to have their feathers burnt off, to the extent that they could not fly”. The larger Grapple Y test in 1958 spread fallout over Kiritimati Island and destroyed large areas of vegetation.
Despite evidence that military personnel and local people suffered serious health problems as a result of the tests, including blindness, cancers, leukaemia and reproductive difficulties, the British government has consistently denied that they were exposed to dangerous levels of radiation and has resisted claims for compensation.
Like the Marshall Islands, the low-lying Republic of Kiribati is now bearing the brunt of the effects of climate change. Salt water washed in on king tides has contaminated the islands’ scarce freshwater resources. Pits that are used to grow taro plants have been ruined and the healthy subsistence lifestyle of local people is under threat.

The UK is set to spend £3.4 billion a year on Trident nuclear weapons system between 2019 and 2070. If Trident were scrapped, a portion of the savings could be provide to the Republic of Kiribati in the form of climate finance (see section 1.2.1). Scrapping Trident would also allow money and skills to be redirected towards measures aimed at drastically cutting the UK’s carbon emissions (see section 1.2.2) – action that Pacific island nations are urgently demanding.
The Marshall Islands
The most devasting incident of radioactive contamination took place 8,000 km from the US mainland during the Castle Bravo test in 1954. The US detonated the largest nuclear weapon in its history at Bikini Atoll in the Marshall Islands, causing fallout to spread over an area of more than 11,000km. Residents of nearby atolls, Rongelap and Utirik, were exposed to high levels of radiation, suffering burns, radiation sickness, skin lesions and hair loss as a result.

Compounding the injustice of nuclear weapons testing, the Republic of the Marshall Islands is now on the frontline of the climate emergency. The government declared a national climate crisis in 2019, citing the nation’s extreme vulnerability to rising sea levels and the “implications for the security, human rights and wellbeing of the Marshallese people”.

At Runit Island, one of 40 islands in the Enewetak Atoll, rising sea levels are threatening to release radioactive materials into an already contaminated lagoon. In the late 1970s, the US army dumped 90,000 cubic metres of radioactive waste, including plutonium, into a nuclear blast crater and covered it with a concrete cap. Radioactive materials are leaking out of the crater and cracks have appeared on the concrete cap. Encroaching salt water caused by rising sea levels could collapse the structure altogether. The Marshallese government has asked the US for help to prevent an environmental catastrophe but the US maintains that the dome is the Marshall Islands’ responsibility. Hilda Heine, then President of the Republic of the Marshall Islands, said of the dome in 2019: “We don’t want it. We didn’t build it. The garbage inside is not ours. It’s theirs.”

The nations that contributed most to the crisis are failing to cut their emissions quickly enough to limit further global heating, leaving the Marshallese at the mercy of droughts, cyclones and rising seas. A recent study found that if current rates of greenhouse gas emissions are maintained, the Marshall Islands will be flooded with sea water annually from 2050. The resulting damage to infrastructure and contamination of freshwater supplies will render the islands uninhabitable.
If the US scrapped its nuclear weapons programme, it could give a portion of the billions of dollars that would be saved to the Republic of the Marshall Islands to help the country mitigate and adapt to climate disruption (see section 1.2.1 on international climate finance). The US could also use the freed-up funds to invest in its own Just Transition away from a fossil-fuel powered economy.
