2007 Doomsday Clock Time: 5 Minutes To Midnight
In 2007 the doomsday clock was set forward by two minutes to 5 minutes to midnight due to the United States and Russia being poised for a nuclear attack in spite of their declining nuclear stockpiles.
In 2007, North Korea also conducted a nuclear test of their own, causing great worry internationally. By 2008 North Korea had accumulated 8 nuclear capable weapons.
The worry of polar ice caps melting, and increase of natural disasters also caused concern for some and played a part in the 2007 increase.
