Global leaders have managed to keep the world from experiencing a nuclear explosion for eight years, four months and 21 days since September 2017. This milestone is notable given that it marks the longest period without a nuclear test in over 80 years.
Historically, scientists questioned whether these tests were necessary at all after Hiroshima and Nagasaki bombings. Robert Oppenheimer declined to attend the first US nuclear test in 1946, citing the lack of new data from "simple laboratory methods." In reality, most nuclear tests were done above ground, producing iconic mushroom clouds, a visual reminder of the devastating effects of these explosions.
It's hard for people today to imagine constant nuclear detonations like they did during the first decades after Hiroshima. The era saw dozens of nuclear tests taking place every year in the late 1950s and early 1960s. Rising fears of civilization-ending nuclear war were prevalent at that time, with many fearing an inevitable catastrophe.
Nuclear testing has led to health issues such as cancer, autoimmune disorders, and other conditions among "downwinders" living near testing sites. The effects of these tests have been estimated to be even broader-reaching, resulting in up to 4 million premature deaths from cancer and other conditions.
The world gradually phased out nuclear testing after the Partial Test Ban Treaty was signed in 1963, which prohibited above-ground detonations. The Comprehensive Nuclear Test Ban Treaty (CTBT) was ratified by 178 countries but not formally ratified by the United States until now.
With increasing tensions between major powers, particularly China and Russia, there are signs that this pause may not last long. In October, President Donald Trump called for US nuclear testing to resume, which could lead to a renewed era of nuclear testing.
Experts warn that such a return would likely benefit adversaries rather than the US, while potentially sparking an even broader arms race. The recent withdrawal of Russian ratification of the CTBT by Vladimir Putin and possible Chinese nuclear tests have added to concerns about the future of the pause in nuclear testing.
The eight-year hiatus without a nuclear explosion serves as a good news story but raises questions about whether this luck will last.
