The time to panic is half-past nigh.

Hold onto your loved ones, little buddies! We’re now only two and a half minutes away from the apocalypse. This morning, the Bulletin of the Atomic Scientists announced its decision to move the Doomsday Clock 30 seconds closer to midnight. In its opening statement, Bulletin’s Editor-in-Chief, John Mecklin, wrote:

“Over the course of 2016, the global security landscape darkened as the international community failed to come effectively to grips with humanity’s most pressing existential threats, nuclear weapons and climate change.”

A little history: Manhattan Project scientists first created the Doomsday Clock in 1947 to function as an indicator of the likelihood of dangerous nuclear conflict. Over time, it has evolved to include other threats, such as climate change, cyber threats and biological weapons.

In 2015, the clock jumped two notches, to three minutes before midnight. Now we’re the closest we’ve been to midnight?—?the hour of the apocalypse?—?since the era of below-ground bunkers and soda-pop shops.

While it’s easy to blame this new development on Trump, it’s slightly more nuanced than that. Other factors that contributed are: Putin.
