This is no scoffing matter. The accelerating proliferation of advanced nuclear weapons is bringing ‘end times’ closer by the day

Humankind has fearfully and sometimes joyfully anticipated the end of the world ever since it began. The Bible’s Book of Revelation speaks of “end times”, a period of tribulation, war, famine, plague, floods and environmental catastrophe that may seem a less absurd prospect today than perhaps it once did. Islam, too, posits a fateful day of judgment or day of reckoning. Christian evangelicals believe that, in the final rapture, a chosen few – the righteous or the “elect” – will be saved while sinners burn. It’s a minority view. Matthew’s gospel predicts most people will defy, ignore or ridicule warnings of imminent Armageddon. Peter, another of Jesus’s disciples, agreed: “In the last days, scoffers will come, scoffing and following their own evil desires.” Yet such worldly scepticism does not mean a universal cataclysm is less likely. It may make it more probable.

Donald Trump’s blanket denials of the dangers ostensibly posed by artificial intelligence, whose uncontrolled development is seen by some as the latest harbinger of apocalypse, could be interpreted as fulfilling Peter’s prophecy. This US president, the nearest thing the world has to a one-man doomsday machine, is a great one for scoffing and evil desires. In Robert Harris’s 2019 novel, The Second Sleep, a worried scientist lists half a dozen ways the world might end. They include devastating climate change, pandemic disease, a giant asteroid collision with Earth, or some other overwhelming calamity. Few heed the fictional scientist’s fears. In the event, what destroys him and almost everybody else is a disturbingly plausible cyber crash – a global digital and internet meltdown.

Newly established commission identifies 17 catastrophic threats to human health but says ‘realistic route to act’ on each exists

Humans could become extinct by the year 2100 due to malicious use of AI or nuclear conflict, according to a new global risk assessment.

They top a list of 17 major threats to human health over the next 75 years, which also includes cuts to aid spending by wealthy countries, the climate crisis and childhood malnutrition.

The International Atomic Energy Agency voices ‘serious concerns’ over expansion of Yongbyon facility to enrich uranium

The International Atomic Energy Agency (IAEA) has voiced “serious concern” over evidence that North Korea has built a facility capable of enriching weapons-grade uranium to bolster its nuclear arsenal.

The new building, located at the the country’s main Yongbyon nuclear facility, can house up to 28 centrifuge cascades – machinery commonly used to enrich uranium – according to a report by the nuclear watchdog released this week.

Chief of nuclear watchdog says secret Assad-era facility would have been able to produce fissile material

A nearly complete nuclear reactor built secretly during the rule of the toppled Syrian leader Bashar al-Assad would have been able to produce fissile material for possible use in nuclear weapons, the chief of the UN nuclear watchdog has revealed.

Inspectors from the International Atomic Energy Agency (IAEA) last month visited two sites, one in Deir ez-Zor and a second in an undisclosed location identified to them by Syrian authorities.

Exclusive: Tobias Ellwood says he gave MPs inaccurate information in 2018 provided by his department, the MoD

• I inadvertently misled parliament over a British nuclear scandal. Now I’m demanding justice

A former defence minister has admitted misleading parliament over the existence of crucial medical records relating to nuclear bomb test veterans.

Tobias Ellwood has said he unwittingly gave MPs incorrect information in 2018 when he told them he had been unable to locate information on veterans’ blood tests after being given incorrect information by officials at the Ministry of Defence (MoD).

The vast majority of the global public wants international cooperation on human rights, climate and AI. Like-minded countries must stand together to deliver

Britain’s new prime minister, Andy Burnham, is already having to make one of his gravest decisions. He has to issue the instructions that he alone gives to the military, setting out the UK response in a doomsday scenario of a nuclear weapons attack on us. He will, as I did two decades ago, sign a piece of paper telling commanders whether or not to retaliate and, if so, whether through targeting civilian conurbations or military sites. These instructions are written down in the aptly named “letter of last resort”.

Now, more than at any time since the 1960s Cuban missile crisis, the European public fears a third world war. With the nuclear Doomsday Clock developed by atomic scientists moving ever closer to midnight, and Japan, South Korea, Saudi Arabia, the UAE, Egypt, Poland and Germany contemplating either acquiring nuclear weapons or siting them on their soil, our world is descending from a rules-based order to a power-based one, where might is deemed right and brute force dominates.

Lee Jae Myung has long pushed for stronger homegrown defences, yet Donald Trump’s move has sparked alarm in some quarters

At their first summit, in August last year, the South Korean president, Lee Jae Myung, told Donald Trump: “If you, Mr President, become the peacemaker, then I will assist you as the pacemaker.”

The remark at the Oval Office captured the thrust of Lee’s approach to North Korea: dial down the military posturing and make repeated peace overtures to revive dialogue, even if they have been consistently rejected by Pyongyang largely over Seoul’s insistence on denuclearisation.
