"The time on the Doomsday Clock represents the judgement of leading science and security experts about the threat to human existence, with a focus on man-made threats." - Bulletin President and CEO @RachelBronson1
"As UN Secretary-General Antonio Guterres warned this past August, the world has entered 'a time of nuclear danger not seen since the height of the Cold War.'" - Bulletin President and CEO @RachelBronson1
"There is no clear pathway for forging a just peace [...] The US government, its NATO allies and Ukraine have a multitude of channels for dialogue; we urge leaders to explore all of them to their fullest ability." - @RachelBronson1
"We move the Clock forward, the closest it has ever been to midnight. It is now, 90 seconds to midnight." #DoomsdayClock

"Nuclear dangers increased significantly last year, due largely to Russia’s unprovoked invasion of Ukraine." - Bulletin Science and Security Board Member  @sfetter
"From almost every prospective, the risk of nuclear catastrophe is higher today than last year." - Bulletin Science and Security Board Member  @sfetter #DoomsdayClock
"Nearly three years after the onset of the COVID-19 pandemic, the world continues to experience the fallout from this disease with no clear end in sight." - Science and Security Board Member @drsuzet #DoomsdayClock
"Strategies for risk assessment and risk mitigation, and the establishment of agreed upon norms for scientific pursuit lag further and further behind, as biological science and technology advance faster and faster." - Science and Security Board Member @drsuzet #DoomsdayClock
"Debilitating illness, widespread death, and disease-induced disaster can be avoided if countries around the world cooperate on global health emergency strategies" - Science and Security Board Member @drsuzet #DoomsdayClock
"With emissions still rising, weather extremes continue, and are even more clearly attributable to climate change." - Science and Security Board Member Sivan Kartha #DoomsdayClock
"The invasion of Ukraine [...] has opened up a geopolitical fissure, weakening the global will to cooperate." - Science and Security Board Member Sivan Kartha #DoomsdayClock
"We live today in a series of interlocking crises, each illustrating the unwillingness of leaders to act in the true long-term interest of their peoples." - Former President of Ireland Mary Robinson @TheElders
"We need urgent multilateral action, and bold, ethical leadership. Frankly, we're not seeing it." - Former President of Ireland Mary Robinson @TheElders
"And whilst these challenges may seem insurmountable, we have no choice but to act. As Nelson Mandela himself said, 'it always seems impossible until it is done.'"
- Former President of Ireland Mary Robinson
@TheElders
"The existential threats outlined today should be a cause for alarm for every citizen on Earth, and even more alarming is the continued failure of decisionmakers to rise to the challenge."
- Former President of Mongolia Elbegdorj Tsakhia
@elbegdorj
#DoomsdayClock
"The urgency of the interconnected existential threats we face requires a crisis mindset from our leaders." - Former President of Mongolia Elbegdorj Tsakhia
@elbegdorj
"The U.S. and Russia have a strong shared interest in avoiding nuclear war...we should be able to pursue this shared interest despite the war in Ukraine." - Bulletin Science and Security Board Member @sfetter #DoomsdayClock
"We're in a situation now where leaders aren't doing what they need to, and we need the public, desperately, to make sure they focus on these key issues about advancing technologies, not only the benefits, but the risks as well." - Bulletin President and CEO @RachelBronson1
"No one can do this alone, but everyone can do something. [...] We all need to pay attention to these key issues." - Bulletin President and CEO @RachelBronson1
"Wake up, leaders! That's the call." - Former President of Ireland Mary Robinson @TheElders
"Renewable energy is set to be the largest group of energy sources in the fairly near future, in the next five years. [...] That's something to take heart in." - Science and Security Board Member Sivan Kartha #DoomsdayClock
"Climate change is in some ways a generational problem. There's a generation growing up now that will be our leaders in the future, that's fired up about climate change." - Science and Security Board Member Sivan Kartha #DoomsdayClock
"I think that our leaders need to not become complacent, but continue to recognize and understand the devastating effects of biological threats." - Science and Security Board Member
@drsuzet #DoomsdayClock1
"The advancement of science brings such potential, but if we don't figure out how to manage the risks associated with them, it's the risks that will lead us rather than the benefits." - Bulletin President and CEO
@RachelBronson1
"With the #DoomsdayClock now, thoughtfully and intentionally, at #90SecondsToMidnight, there really is no time to waste."
- Bulletin President and CEO @RachelBronson1

THREAD: In a nuclear war, hundreds or thousands of detonations would occur within minutes of each other. Smoke from mass fires after the detonations would inject massive amounts of soot into the stratosphere.
As this simulation from @AlanRobock illustrates, a nuclear war between the US & Russia, could waft more than 150 Tg of soot into the stratosphere, leading to a nuclear winter that would disrupt virtually all forms of life on Earth over several decades.
Injecting this much soot into the stratosphere could make global temperatures drop by 8 degrees Celsius—3 degrees lower than Ice Age values.

THREAD: Here's how this 1998 thriller novel helped jumpstart the creation of the US Strategic National Stockpile ⬇️ Image
The Cobra Event is a novel by Richard Preston that tells the story of a madman who engineered a virus called “brain-pox” and unleashed it on New York City.

It was widely criticized when it published.

However, at least one high-profile reader was a fan: Bill Clinton. Image
After reading the book, Clinton asked a tech entrepreneur if terrorists could engineer a worse version of the smallpox virus.

The entrepreneur told him they could and recommended Preston’s book.
