The end is nigh? Climate, nuclear crises spark fears of worst

But Benedict also faulted the Biden administration's nuclear posture review which reserved the right for the United States to use nuclear weapons in "extreme circumstances."

For thousands of years, predictions of apocalypse have borne little fruit. But with dangers rising from nuclear war and climate change, does the planet need to at least begin contemplating the worst?

When the world rang in 2022, few would have expected the year to feature the US president speaking of the risk of doomsday, following Russia’s threats to go nuclear in its invasion of Ukraine.

“We have not faced the prospect of Armageddon since Kennedy and the Cuban missile crisis” in 1962, Joe Biden said in October.

And on the year that humanity welcomed its eighth billion member, UN Secretary-General Antonio Guterres warned that the planet was on a “highway to climate hell.”

In extremes widely attributed to climate change, floods submerged one-third of Pakistan, China sweat under an unprecedented 70-day heatwave and crops failed in the Horn of Africa, all while the world lagged behind on the UN-blessed goal of checking warming at 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels.

– Biggest risk yet of nuclear war? –

The Global Challenges Foundation, a Swedish group that assesses catastrophic risks, warned in an annual report that the threat of nuclear weapons use was the greatest since 1945 when the United States destroyed Hiroshima and Nagasaki in history’s only atomic attacks.

The report warned that an all-out exchange of nuclear weapons, besides causing an enormous loss of life, would trigger clouds of dust that would obscure the sun, reducing the capacity to grow food and ushering in “a period of chaos and violence, during which most of the surviving world population would die from hunger.”

Kennette Benedict, a lecturer at the University of Chicago who led the report’s nuclear section, said risks were even greater than during the Cuban Missile Crisis as Russian President Vladimir Putin appeared less restrained by advisors.

While any Russian nuclear strike would likely involve small “tactical” weapons, experts fear a quick escalation if the United States responds.

“Then we’re in a completely different ballgame,” said Benedict, a senior advisor to the Bulletin of the Atomic Scientists, which in January will unveil its latest assessment of the “doomsday clock” set since 2021 at 100 seconds to midnight.

Amid the focus on Ukraine, US intelligence believes North Korea is ready for a seventh nuclear test, diplomacy has been at a standstill on Iran’s contested nuclear work and tensions between India and Pakistan have remained at a low boil.

But Benedict also faulted the Biden administration’s nuclear posture review which reserved the right for the United States to use nuclear weapons in “extreme circumstances.”

“I think there’s been a kind of steady erosion of the ability to manage nuclear weapons,” she said.
