If the end of the world were nigh, and the world’s biggest brains trying to stop it.

Some of Britain's finest minds are drawing up a "doomsday list" of catastrophic events that could devastate the world, pose a threat to civilisation and might even lead to the extinction of the human species.

Leading scholars have established a centre for the study of "existential risk" which aims to present politicians and the public with a list of disasters that could threaten the future of the world as we know it.

Lord Rees of Ludlow, the astronomer royal and past president of the Royal Society, is leading the initiative, which includes Stephen Hawking, the Cambridge cosmologist, and Lord May of Oxford, a former government chief scientist.

The group also includes the Cambridge philosopher Huw Price, the economist Partha Dasgupta and the Harvard evolutionary geneticist George Church. Initial funding has come from Jaan Tallinn, the co-founder of Skype.

"Many scientists are concerned that developments in human technology may soon pose new, extinction-level risks to our species as a whole," says a statement on the group's website.

Lord Rees said in his closing speech to the British Science Festival in Newcastle this evening that the public and politicians need the best possible advice on low-risk scenarios that may suddenly become reality, with devastating consequences.

"Those of us fortunate enough to live in the developed world fret too much about minor hazards of everyday life: improbable air crashes, carcinogens in food, low radiation doses, and so forth," Lord Rees told the meeting.

"But we are less secure than we think. It seems to me that our political masters, should worry far more about scenarios that have thankfully not yet happened – events that could arise as unexpectedly as the 2008 financial crisis, but which could cause world-wide disruption," he said.

Professor David Spiegelhalter, an expert in risk at Cambridge University, said that our increasing reliance on technology and the formation of complex interconnected networks is making society more vulnerable.

"We use interconnected systems for everything from power, to food supply and banking, which means there can be real trouble if things go wrong or they are sabotaged," Professor Spiegelhalter said.

"In a modern, efficient world, we no longer stockpile food. If the supply is disrupted for any reason, it would take about 48-hours before it runs out and riots begin," he said.

"Energy security is also an issue, as we import much of our fuel from abroad, so a conflict over resources in the future is possible," he added.

According to Lord Rees, the threat of nuclear war was the main global risk we faced in the last century, but in the fast-developing 21st Century there are new concerns over risks such as deadly bioterrorist attacks, pandemics accelerated by global air travel, cyberattacks on critical infrastructure and artificially intelligent computers that turn hostile.

"In future decades, events with low probability but catastrophic consequences may loom high on the political agenda," Lord Rees told the science festival.

"That's why some of us in Cambridge – both natural and social scientists – plan, with colleagues at Oxford and elsewhere, to inaugurate a research programme to compile a more complete register of these existential risks, and to assess how to enhance resilience against the more credible ones," he said.
