Interesting concept the "Doomsday Clock"... I remember as a kid how terrified I was of nuclear war in the late 80"s and early 90"s.

At around "11:58" was about when my grandparents built a huge bomb shelter in their back yard (which was a common practice for some in the US) in the 1950's. It, of course, ultimately morphed into a recreational cave for my mom and her siblings, that reeked of mildew, but who knew...
 
I hope they do factor in climate change when determining how near we are to self-destructing, and that people do take it as a serious threat that needs to be addressed immediately.

p.s. no need to panic though...according to the date on today's LAM news ticker, we have an extra week folks...
