The Bulletin of the Atomic Scientists has  posted the following on their website:

“For the last two years, the minute hand of the Doomsday Clock stayed set at three minutes before the hour, the closest it had been to midnight since the early 1980s. In its two most recent annual announcements on the Clock, the Science and Security Board warned: “The probability of global catastrophe is very high, and the actions needed to reduce the risks of disaster must be taken very soon.” In 2017, we find the danger to be even greater, the need for action more urgent. It is two and a half minutes to midnight, the Clock is ticking, global danger looms.”

Uh…  not great.  I already wrote about the Doomsday Clock earlier and remain optimistic about our future.  In the meantime, this is some of the data the “atomic scientists” are using to make their conclusions:

I understand why they are concerned.
