WASHINGTON – Atomic scientists on Jan 23 kept their “Doomsday Clock” set as close to midnight as ever before, citing Russia’s actions on nuclear weapons amid its invasion of Ukraine, nuclear-armed Israel’s Gaza war and worsening climate change as factors driving the risk of global catastrophe.
The Bulletin of the Atomic Scientists, as they did last year, set the clock at 90 seconds to midnight – the theoretical point of annihilation. Scientists set the clock based on “existential” risks to Earth and its people: nuclear threats, climate change and disruptive technologies such as artificial intelligence and new biotechnology.
“Conflict hot spots around the world carry the threat of nuclear escalation, climate change is already causing death and destruction, and disruptive technologies like AI and biological research advance faster than their safeguards,” Dr Rachel Bronson, the Bulletin’s president and chief executive officer, told Reuters, adding that keeping the clock unchanged from the prior year is “not an indication that the world is stable.”
The Chicago-based nonprofit created the clock in 1947 during the Cold War tensions that followed World War II to warn the public about how close humankind was to destroying the world. It said on Jan 23 that ominous trends continue to point toward catastrophe, including the fact that China, Russia and the United States all are spending large amounts of money to expand or modernise their nuclear arsenals, boosting the risk of nuclear war through mistake or miscalculation.
Russia’s full-scale invasion of Ukraine, set to reach its second anniversary in February, has escalated tensions with the West to their most dangerous levels since the Cold War.
“A durable end to Russia’s war in Ukraine seems distant, and the use of nuclear weapons by Russia in that conflict remains a serious possibility. In the past year Russia has sent numerous worrying nuclear signals,” Dr Bronson said.
Dr Bronson cited Russian President Vladimir Putin’s February 2023 decision to suspend Russian participation in the New Start treaty with the United States that limited the strategic nuclear arsenals of the two countries. The United States and Russia together hold nearly 90 per cent of the world’s nuclear warheads, enough to destroy the planet many times over.
Dr Bronson additionally cited Mr Putin’s March 2023 announcement of Russia’s deployment of tactical nuclear weapons in Belarus and the Russian parliament’s October 2023 passage of a law withdrawing ratification of the global treaty banning nuclear weapons tests. Russian analyst Sergei Karaganov in 2023 also spoke of the need to threaten nuclear strikes in Europe in order to intimidate and “sober up” Moscow’s enemies.
Traditional nuclear arms control has come to an end for now even as a three-way nuclear arms race is shaping up among China, Russia and the United States, said Professor Alexander Glaser of Princeton University, a member of the Bulletin’s board of experts on nuclear technology and climate science.
“The picture is quite bleak on the nuclear side this year,” Prof Glaser added.
