Dooms Day Clock

The so called Dooms Day Clock has been moved back one minute. All that I can say is, "Huh?" It all seems very arbitrary. In 2007 they moved the Clock forward two minutes because there was an increased threat from nuclear weapons and global warming. Now they moved it back one minute because progress is being made to reduce those threats. Really? In just two years? I find that very hard to believe. Colour me doubtful.
