The keepers of the "Doomsday Clock" plan to move its hands forward next Wednesday to reflect what they call worsening nuclear and climate threats to the world.

The symbolic clock, maintained by the Bulletin of Atomic Scientists, currently is set at seven minutes to midnight, with midnight marking global catastrophe.

The group did not say in which direction the hands would move. But in a news release previewing an event next Wednesday, they said the change was based on "worsening nuclear, climate threats" to the world.

"The major new step reflects growing concerns about a 'Second Nuclear Age' marked by grave threats, including: nuclear ambitions in Iran and North Korea, unsecured nuclear materials in Russia and elsewhere, the continuing 'launch-ready' status of 2,000 of the 25,000 nuclear weapons held by the U.S. and Russia, escalating terrorism, and new pressure from climate change for expanded civilian nuclear power that could increase proliferation risks," the release reads.

False Authority Fallacy:

This fallacy is committed when the person in question is not a legitimate authority on the subject. More formally, if person A is not qualified to make reliable claims in subject S, then the argument will be fallacious.

If I wanted to know how to initiate nuclear fusion, or how much energy a given reaction will release, I would certainly consult an atomic scientist.

But if I wanted to know how likely it was that some politician or terrorist, somewhere in the world, would choose to detonate an atomic weapon, a man who has spent his life in the lab thinking about atomic physics would be among the very last people I would ask.
