The Bulletin of the Atomic Scientists [15] on Jan. 26 moved the minute hand [16] of its symbolic Doomsday Clock from three minutes [17] to two-and-a-half minutes to midnight. On this year that marks the 70th anniversary of the Doomsday Clock, the Bulletin notes (full text at PDF [18]; links added by CountrerVortex [19]): "The United States and Russia—which together possess more than 90 percent of the world's nuclear weapons—remained at odds in a variety of theaters, from Syria to Ukraine to the borders of NATO [20]; both countries continued wide-ranging modernizations [21] of their nuclear forces, and serious arms control negotiations were nowhere to be seen. North Korea conducted its fourth and fifth underground nuclear tests [22] and gave every indication it would continue to develop nuclear weapons delivery capabilities. Threats of nuclear warfare hung in the background as Pakistan and India faced each other warily across the Line of Control in Kashmir after militants attacked [23] two Indian army bases."
The Bulletin finds that the climate change outlook is "somewhat less dismal"—but only somewhat. "In the wake of the landmark Paris climate accord [24], the nations of the world have taken some actions to combat climate change, and global carbon dioxide emissions were essentially flat in 2016, compared to the previous year. Still, they have not yet started to decrease; the world continues to warm. Keeping future temperatures at less-than-catastrophic levels requires reductions in greenhouse gas emissions far beyond those agreed to in Paris—yet little appetite for additional cuts was in evidence at the November climate conference in Marrakech."
The moving of the Clock was clearly motivated by the rise of Donald Trump [25]: "This already-threatening world situation was the backdrop for a rise in strident nationalism worldwide in 2016, including in a US presidential campaign during which the eventual victor, Donald Trump, made disturbing comments about the use and proliferation of nuclear weapons and expressed disbelief in the overwhelming scientific consensus on climate change."
The Bulletin states that its Science and Security Board [26] takes a "broad and international view of existential threats to humanity, focusing on long-term trends" rather than "the statements of a single person." However, "wavering public confidence in the democratic institutions required to deal with major world threats do a ect the board’s decisions. And this year, events surrounding the US presidential campaign—including cyber offensives [27] and deception campaigns [28] apparently directed by the Russian government and aimed at disrupting the US election—have brought American democracy and Russian intentions into question and thereby made the world more dangerous than was the case a year ago."
