#NuclearWinter

New post about the state of research around nuclear war and nuclear winter, with a focus on the food system.

This one's a bit different, as it was originally an invited contribution to the United Nations Independent Scientific Panel on the Effects of Nuclear War. I also wanted to share it publicly, because I think there just aren't that many summaries of the state of nuclear winter research out there.

It also discusses the most important gaps and unanswered research questions in the field. So, if you are interested in the topics in general or plan to work in the area, I think it could be an interesting read.

I woke up to my dog sneezing and my skin itching because it’s FUCKING COLD outside. I filled the humidifier, set the heat to the daytime setting, and then checked the weather network. I currently reside in Brockville, and it’s damn cold, but I also saw the temperature in my childhood hometown of Marathon. Comparison may be the thief of joy, but it also gives incredible context and reminds me that I have experienced much worse than this moment. Im also glad to see proof that I’m not making shit up when I tell people I’ve experienced-50°.

Hey Canadians on Mastodon, what hashtag are we using for this fucked up weather weekend? #NuclearWinter? #FuckItsCold? #LongerShortWeather?

It’s currently -24°, feels like -30°. Tomorrow’s high is -20° and then we get 20cm snow the next day.

Another question: does an extreme cold warning justify #StormChips? It’s not a STORM so to say, but we’re in a Yellow warning for the cold so I feel like it’s a good excuse for chips.

Suppose a Totalitarian World Order built on the genocide of indigenous people and the theft of their resources can obtain peace. What happens next? The great nuclear powers turn on their own people. Well it’s already happening, so Trotsky will get his world revolution or heat death? He just got the timing wrong as Marx foresaw? Does all have to turn to shit first so the Orange Turd can text, the words that lie, “I told you so!”. With weak and MAD despots, oligarchs, plutocrats, theocrats and their techno fascist celebrity cults, only a barren Earth covered in toxic ash can be promised. #ResistWeakMen #TheGreatICEDeath #NuclearWinter #UnitedSpaceShip ? #LiarsPromises #FateOfEmpires #EcocideEmpires #BiosphereCollapse #UnitedShitHoleEnforcement #TWO #TheFederation #USSEnterprise

22/25 🧵 He said I looked too relaxed. Why shouldn't I be? When you understand that the train to Berlin and the train to the apocalypse share the same platform, you stop worrying about being late. Putin knows this. He’s family. My family knows the rhythm of the rails.

Survivors 2070 Part Four: Signs of Change Below

A New Discovery

Three years into the mission, AI sensors detected a temperature rise over the equator. It was small, less than one degree. But it was the first shift in a frozen world.

Alina ran simulation models.

“If this trend continues, surface thaw begins in twelve years.”

Marcus looked at the hologram. “We cannot survive up here indefinitely.”

Rajan said, “Then Earth is our only future.”

The news spread. People cheered. Some cried. Others became anxious.

New Concerns

The outer panels began to degrade. Micrometeoroid strikes increased. Replicators could not replace certain alloy composites. Engineers predicted structural failure in fifteen years.

Elias brought the issue to the council.

“We need a long-term plan. If Earth recovers, we must be ready. If not, we need alternative habitats.”

Rajan replied, “We return home. That is the only path.”

Later, in private, Marcus admitted to Alina,

“We may not have a choice. Halo Arc is aging faster than expected.”

Preparing for Descent

Teams began mapping possible landing zones. Temperatures were lowest in the northern hemisphere. Some equatorial regions looked survivable. Radiation levels remained high in certain areas but were manageable.

Lila told her students,

“One day you will walk on Earth. Our goal is to keep you ready for that moment.”

A boy asked, “Will it still look like the pictures?”

Lila paused. “Different. But still ours.”

Survivors 2070 Part One: The Launch Before the Freeze

The Beginning

The station called Halo Arc had been circling Earth for four years before the first missile was launched. Every nation involved understood they had built the only safe place left for humanity. Europe, America, Canada, Australia, the Netherlands, Finland, Iceland, New Zealand, and the UK. They all contributed people and technology. They selected scientists, doctors, nurses, physicists, engineers, agricultural specialists, and a small group of cultural scholars.

The final selection came down to 3000 people. Each candidate passed genetic screenings, psychological tests, and political neutrality checks. Every person had to work. No passengers. No celebrities. No politicians other than one representative, whose job was negotiation and conflict resolution.

Inside the briefing room in Geneva, Dr. Alina Varga looked at the panel of world leaders.

“We are cutting it close,” she said. “Satellite data shows the first Arctic detonations within six months.”

President Collins of the United States leaned forward. “Then we move today. We cannot wait for a perfect moment. We need the launch sequence ready.”

Prime Minister Henriksen of Iceland nodded. “Every extra day on Earth increases the chance of failure.”

The room fell silent as Colonel Yasmin Rajan entered.

“Launch initiates in nine hours,” she said.

No one argued. Humanity was out of time.

Why the Mission Existed

Two decades of rising tensions and retaliations pushed nations into defensive stockpiles. The final blow came from a failed peace agreement in 2068. By early 2069, Earth’s surface temperatures had started falling. Nuclear winter projections grew worse every month. The Halo Arc program became the only insurance policy.

Politicians did not get to choose who entered Halo Arc. A coalition of scientists and AI evaluators made the final list. People selected had to rebuild civilization if Earth became uninhabitable.

Departure

As the shuttles lifted, the chosen watched the world glow beneath them. Clouds spread like a white blanket across the continents. The air already showed signs of cooling. Alina gripped the seat handles.

“Goodbye,” she whispered.

Beside her, Dr. Marcus Finn adjusted his visor. “If we do this right, we come back.”

“If Earth lets us,” she replied.

The Halo Arc opened its docking ring. The future of humanity began with a quiet click of magnetic locks.

#ClimateChange, #NuclearWinter, and #StratosphericAerosolInjection are all human-made interventions in the climate system. They share the potential to be massively disruptive to the habitability of this planet. Usually, we see them as separate catastrophes, but this does not have to be the case. It could easily happen that we face two of them at the same time, or even all three if we get really unlucky. In my newest post, I explain all three of them and what interactions we might face if we end up in the unfortunate timeline where we have to face several of them at the same time.

The louder you play it, the better it is. Eve of Destruction, a Vietnam protest song. Considering the times in which we live, fascism, autocracy, nuclear winter, this song seems as appropriate now as it was then. #NuclearWinter #EveOfDestruction #TraitorTrump #86TACO

Each time a nuclear bomb goes off, debris is spewed into the air. As many bombs go off, sunlight is cut off, resulting in a nuclear winter. In a nuclear winter, all life dies. When Trump refuses to yield power in 2028, he might use nuclear devices against blue states. #86TACO #NuclearWinter

@br00t4c There we go, the 🖤 blackmailers present their last or desperate call: ‘Billionaire Donald Trump Backer Warns America Of 'Self-Induced Economic Nuclear Winter'’?

Will the people’s response be: if we go down, so do you! Playing the #TheRedDeath game. Do the oligarchs really desire a gunfight at the O.K.

Nuclear Winter Series I-V by Bobby Akart, 2021

Post Apocalyptic Survival Thriller

Nuclear fallout circled the Earth like a blanket of death. Temperatures plummeted. Crops and livestock died. Man turned on man in a desperate attempt to survive. And it was just the beginning.

"Masterful and suspenseful!"

@bookstodon



This is how the world ends. Not with a bang, but with many nuclear bombs detonated around the planet. It was no longer a topic of conversation around the dinner table as in years past. Nobody was prepared, including the world's governments. Yet the threat was always real and the devastation was predictable. "Bobby's uncanny ability to take a topic of what could happen and write an epic story about it is short of preternatural!" The damage was incalculable. Millions died at the points of impact. Nuclear Winter spread across the globe. A rapidly cooling climate shocked humanity and all living things ... to their death. Akart's new Nuclear Winter series depicts a world on the edge of nuclear Armageddon. Nuclear Armageddon became reality and ordinary Americans are paying the price. "I never would have believed that Mr. Akart could outdo himself! Well, he has! This series is quite possibly the best he has ever written. 
" This is more than the story of nuclear conflict. It's about the devastating effects wrought by Nuclear Winter. Our possible future is seen through the eyes of the Albright family whose roots stretch back to the early settlement of the Florida Keys. While they fight for survival, they trek across a rapidly deteriorating landscape wrought with danger from both the elements and their fellow man. It was not our fight, but it became our problem. "I am speechless. By far the most edge of your seat, acrylic nail biting book ever. E V E R." Bobby Akart has delivered intense, up-all-night thrillers that have you whispering just one more chapter until the end.

* Evgeny P. Velikhov * 1935 - 2024

One brilliant Russian Physicist who probably stopped WWIII ... so far.

#NuclearWinter #BlackHoles #Russia #USA #ColdWar #Memoriam #Moskva

Velikhov and three colleagues testified at a US Senate forum on the possibility of nuclear war causing a “nuclear winter.”[5] In June 1984, Velikhov published a critique of the feasibility of space weapons in the Washington Post.

February 1987, Velikhov organized eight parallel international forums in Moscow to discuss how to achieve “A Nonnuclear World for the Survival of Mankind.”

As Velikhov told one of us in 1990, when the hard-liners were beginning to mobilize against Gorbachev, “You should not fall dead before you are shot.”

@acm_redfox Also -- some idiots actually believe that #NuclearWinter will solve #GlobalWarming. I came across a number of those articles a few hours ago!
