A few days ago the Bulletin of Atomic Scientists moved the nuclear clock forward to 11:55PM, which means that we are five minutes from nuclear annihilation.  I find this kind of alarmist brinkmanship surprising, coming from scientists, though it has been moved seventeen times before since 1945, all the way up to 11:58PM. So I suppose in the scheme of things, we are fine — in fact twice as fine as before, when we were not fine.
