The Bulletin of the Atomic Scientists will host a live virtual news conference at 10:00 a.m. EST/1500 GMT on Thursday, Jan. 20 to announce the 2022 Doomsday Clock time and commence the 75th anniversary of the iconic Clock.

The announcement can be viewed on the Bulletin’s website or its Facebook page.

For 75 years, the Doomsday Clock has acted as a metaphor for how close humanity is to self-annihilation. Since 1947, it has also served as a call-to-action to reverse the hands, which have moved backwards before. The Doomsday Clock is set annually by the Bulletin’s Science and Security Board in consultation with the organization’s Board of Sponsors.

The 2022 Doomsday Clock program will feature remarks from:

• Hank Green, science communicator, vlogger, and New York Times best-selling author (An Absolutely Remarkable Thing). Hank is known for producing the popular YouTube channel Vlogbrothers with his brother, author John Green (The Fault in Our Stars, Paper Towns, Turtles All the Way Down);
• Rachel Bronson, PhD, president and CEO, Bulletin of the Atomic Scientists;
• Asha M. George, DrPH, executive director, Bipartisan Commission on Biodefense, and member, Science and Security Board (SASB), Bulletin of the Atomic Scientists;
• Herb Lin, PhD, senior research scholar for cyber policy and security at the Center for International Security and Cooperation and Hank J. Holland Fellow in Cyber Policy and Security at the Hoover Institution at Stanford University, and member, Science and Security Board (SASB), Bulletin of the Atomic Scientists;
• Sharon Squassoni, research professor at the Institute for International Science and Technology Policy, Elliott School of International Affairs, at the George Washington University, and co-chair, Science and Security Board (SASB), Bulletin of the Atomic Scientists;
• Scott D. Sagan, PhD, Caroline S.G. Munro Professor of Political Science, the Mimi and Peter Haas University Fellow in Undergraduate Education, and Senior Fellow at the Center for International Security and Cooperation (CISAC) and the Freeman Spogli Institute (FSI) at Stanford University, and member, Science and Security Board (SASB), Bulletin of the Atomic Scientists; and
• Raymond Pierrehumbert, PhD, Halley Professor of Physics at the University of Oxford, lead author on the IPCC Third Assessment Report, and member, Science and Security Board (SASB), Bulletin of the Atomic Scientists.

The Doomsday Clock’s 75th anniversary will also be memorialized in a coffee table book that explores how the powerful symbol has impacted culture, politics, and global policy—and helped shape discussions and strategies around nuclear risk, climate change, and disruptive technologies.
