This interactive data visualization looks at changes in The Bulletin of the Atomic Scientists’ Doomsday Clock between 1947 and 2017. Upon being set at “7 minutes to midnight in 1947”, the hands on the clock have changed position 22 times for various reasons. Most recently, the clock changed to 2.5 minutes to midnight in January 2017; this is the closest to midnight the clock has been since 1953.
The end user can hover over any data point in the visualization to see the year, minutes to midnight during that year, the change from the previous position, and the reason the clocked moved position that year. The clock, nor this visualization, are meant to be political. You can read FAQs about the clock by clicking the link in the top right corner of the visualization. I was interested in visualizing this story to quickly see the history of nuclear and other global threats.
