Did Anyone Even Know That There Was a Doomsday Clock?

Personally, it came as a big surprise that there actually is a real-life doomsday clock that scientists use. In 2002, the group moved the clock two minutes closer to midnight to represent that time was running out even faster toward the end of time. The group is expected to do the same again this wednesday evening, even though no formal statement saying so has been made.
A news release sent out by the group that are in charge of the clock stated: "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."
This statement has prompted the scientific community to believe that the clock's hand will once again be moving closer to midnight aka "doomsday" on wednesday evening.
I personally think this is the dumbest idea that I have ever heard of. Why is their a clock telling us when we will probably all die due to some catastrophic event? Anyone is their right mind can already tell that their is growing nuclear hostility and global warming is knocking at our back door. We do not need some silly group with a big clock to tell us.
