While we have 'joked' about it in the past, Elliott Management's Paul Singer believes "there is one risk that stands way above the rest in terms of the scope of potential damage adjusted for the likelihood of occurrence" - an electromagnetic pulse (EMP).

Not a laughing matter....
Exceprted from Elliott Management's latest letter from Paul Singer,
EMP: THE MOST SIGNIFICANT DANGER
While these pages are typically overflowing with scary or depressing scenarios, there is one risk that stands way above the rest in terms of the scope of potential damage adjusted for the likelihood of occurrence. Even nuclear war is a relatively localized issue, except in its most extreme form. And the threat from asteroids can (possibly) be mitigated.
The risks associated with electromagnetic pulse, or EMP, represent another story entirely. It can occur naturally, from solar storms that send “coronal mass ejections,” which are massive energetic bursts of solar wind, tens of millions of miles in a mere few hours. Or it can be artificial, produced by a high-altitude (at least 15 miles) explosion of relatively low-yield (even Hiroshima-strength) nuclear weapons.
Different initiators of EMP have different pulses and different effects. But the bottom line is that EMP fries electronic devices, including parts of electric grids. In 1859, a particularly strong solar disturbance (the “Carrington Event”) caused disruption to the nascent telegraph network. It happened again with similar disruptions in 1921, before our modern power grid came into existence. A NASA study concluded these events have typically occurred around once per century. A repeat of the Carrington Event today would cause a massive disruption to the electric grid, possibly shutting it down entirely for months or longer, with unimaginable consequences.
Only two years ago, the sun let loose with a Carrington-magnitude burst, but the position of the earth at the time prevented the burst from hitting it. The chances of additional events of such magnitude may be far greater than most people think.
The artificial version of EMP, a kind of nuclear attack, would require between one and three high-altitude nuclear explosions to create its effect across all of North America. It would not cause any blast or radiation damage, but such an attack would have consequences even more catastrophic than a severe solar storm. It could not only bring down the grid, but also lay down a very intense, very fast pulse across the continent, damaging or destroying electronic switches, devices, computers and transformers across America.
There is no way to stop a naturally occurring EMP, and nuclear proliferation, combined with advances in weapons delivery systems, make the artificial version a distinct possibility, so the dangers are very real.
What can be done about this risk? Critical elements of the power grid and essential electronic devices can be hardened. Spare parts can be stockpiled for other, less critical hardware. Procedures can be developed as part of emergency preparedness so that the relevant government agencies and emergency response NGOs are ready to respond quickly and effectively to an episode large or small.
Why are we writing about EMP? Because in any analysis of societal risk, EMP stands all by itself. Congressional committees are studying this problem, and federal legislation is laboriously working its way through the process. We think that raising people’s consciousness about what should be an effort by both parties to make the country (and the world) safer from this kind of event is a good thing to do.
