Scientists Join Sen. Markey to Oppose Resumption of Nuclear Testing

Senator Markey

by Jerry Ross and Jonathan Alan King

On the 75th anniversary of the first nuclear test explosion in the New Mexico desert, leading scientists from across the country joined Senator Edward J. Markey at a virtual press conference to express their strong opposition to the Trump Administration’s threats to resume the US nuclear testing program. The scientists endorsed the PLANET Act, S.3886, legislation introduced by Sen. Markey and 13 other senators, that would prohibit the use of federal funds for nuclear weapons testing.  

The July 16th press conference, organized by Massachusetts Peace Action, announced the publication of an Open Letter in the July 17th issue of Science magazine warning that a resumption of testing would pose major public health hazards, fuel a new nuclear arms race, and possibly lead to accidental or intentional nuclear war. Seventy scientists and other experts, including several Nobel laureates, signed the letter. 

“Last month, the Trump Administration made the terrifying announcement that it won’t carry out a nuclear test at this time,” said Boston University Prof. Sheldon Glashow, 1979 Nobel Prize for Physics. “To do so would be an act of madness. Rather…we must strive to reduce and at last eliminate the world’s vast accumulation of these infernal and unnecessary nuclear warheads.” 

Over several decades, the United States conducted 1,030 nuclear weapons test explosions, more than the combined total of tests by all other countries. The US government stopped its atmospheric testing of nuclear weapons in 1962, shortly before signing the Partial Test Ban Treaty of 1963. It halted underground nuclear tests in 1992 and signed the Comprehensive Test Ban Treaty in 1996. (A Republican-controlled Senate blocked ratification of that treaty, but the US and 183 other countries have adhered to its provisions anyway.) 

But the Trump Administration is now engaging in serious discussions about resuming nuclear testing. Sen. Tom Cotton, a Republican Trump supporter from Arkansas, has inserted an amendment into the National Defense Authorization Act (NDAA) that allocates “no less than $10 million” for resumption of nuclear weapons testing “if necessary.” The NDAA is currently under debate in Congress. 

Sen. Markey, the leading proponent of nuclear arms control and disarmament in the US Senate, said, “Trump’s advisors think that threatening to restart testing…will somehow lead China and Russia to the negotiating table. In reality, it will open the floodgates to parallel tests by those countries and by others, fueling a 21st century nuclear arms race.” 

The senator highlighted the environmental and public health dangers new testing would pose. “A return to US nuclear testing would…expose a whole new generation of Americans to the horrors of radiation sickness,” Markey said. Prior to the 1963 atmospheric test ban, nuclear tests were carried out aboveground, releasing radioactive isotopes that were carried into the atmosphere and slowly returned to the ground. The campaign in the US to stop the testing was led by chemist Linus Pauling, his wife Ava Helen, and thousands of scientists. The effort revealed that radioactive strontium-90 from fallout was accumulating in milk, bones, and even baby teeth. This campaign, which mobilized mothers across the nation, together with President John Kennedy’s effort to pull back from the 1962 Cuban Missile Crisis, led the US Senate to ratify the atmospheric test ban treaty in 1963. 

Tufts Prof. Sheldon Krimsky, a leading public health expert, noted that continued research has shown even underground nuclear testing results in significant leakage of radioactivity into both underground water systems and into the air. 

The wide-ranging comments by scientists at the press conference were sobering and insightful. Nobel Laureate in Physics Jerome Friedman noted that Trump’s resumption of testing would give other nuclear powers the excuse to begin testing again, expand their arsenals, and disregard the few remaining nuclear treaties. Rutgers climate scientist Alan Robock described the “nuclear winter” that a nuclear exchange would bring about, when smoke from fires would be lofted into the atmosphere, blocking the sunlight and causing global famine and death. Others linked the issue to the Covid-19 pandemic. Max Tegmark, MIT physics professor, said the pandemic has shown that very low-probability but enormously destructive events can and do occur, and reminded the press that the world has had several close calls with accidental nuclear catastrophe. 

Catherine Royer, a biologist at Rensselaer Polytech and president of the Biophysical Society, noted that nuclear testing would devour funds needed for legitimate scientific research, such as prevention and cure of pandemics like Covid-19. Bill Hartung, of the Center for International Policy, pointed out that major corporations have an interest in the resumption of testing, which would lead to the development and manufacture of new, highly profitable weapons systems. 

Harvard Prof. of Aesthetics Elaine Scarry, author of Thermonuclear Monarchy, wrapped up the presentations with a succinct summary of the moral implications of the US President’s ability to unilaterally incinerate millions: “The current nuclear architecture in the United States arranges for a solitary person – the president – to launch a nuclear weapon without authorization from Congress or the population or any advisors. Similar arrangements exist in the other nuclear states. Given the extraordinary danger of nuclear catastrophe, any step that further enables nuclear warfare – such as the resumption of testing – should be morally unthinkable.”
