#nuclearwinter — Public Fediverse posts

Labour’s priorities are totally wrong

This week, the government published the long-delayed Defence Investment Plan, which increases military spending by a further £15 billion, with military spending planned to rise even more to nearly £80 billion per year by 2029. This will be at the expense of other much-needed projects.

Keir Starmer said that the government will be spending £64 billion on nuclear weapons over the next four years. This is 20% of our defence spending. It’s enough money to build 64 brand new hospitals or 18 massive offshore wind farms, which would make us much more self-reliant. 

Labour’s priorities are totally wrong. I acknowledge the threat of Russia, but what use are nuclear weapons against them? Relying on nuclear weapons drags the world closer towards a nuclear conflict. Should they ever be used, they won’t just kill millions, if not billions, of innocent people, but they would throw so much ash up into the atmosphere that it would lead to a nuclear winter, where the sun is blocked out. This would mean ecocide as well as genocide, and it would be impossible to grow food.

Using drones in warfare is deeply concerning. In Gaza, Israel has programmed drones to broadcast the sound of Palestinian babies crying or children shouting “I want my mother”. Of course, this brings out concerned residents, looking for the child, at which point the soldiers shoot them.

Defence spending should be directed to defence, not to weapons of mass destruction.  What we need are systems that can protect us from drone warfare.

Meanwhile, our greatest security threat is the climate crisis. We need our forces ready to set up emergency flood barriers, rescue flood victims, fight wildfires and support the NHS when heatwaves overwhelm it. Governments’ priority should be urgently reducing our reliance on fossil fuels and preparing our nation to cope with the more extreme weather just around the corner. 

Nuclear war is horrible and I hope it never happens. Yet, there are only a few countries that actually have nuclear weapons and the power to use them is concentrated in just a few individuals. This means the vast majority of the global population has no say on the question if nuclear weapons will be used.

However, due to a potential nuclear winter, which could follow a nuclear war, even countries on the other side of the globe could be directly affected by a nuclear war. This impact could be quite severe and as they have no direct measure to prevent it, these countries should think about how they would prepare. Also, many of the preparations that would be helpful for a nuclear winter would also help for the climatic consequences of large volcanic eruptions or asteroid impacts. So, they should be done anyway.

This is the gist of the argument I made in a new article in the Bulletin of the Atomic Scientists. You can read the full article here: https://thebulletin.org/2026/05/how-nuclear-war-would-impact-the-global-food-system-and-how-to-prepare-for-it/

The Season of the #Daleks is after #nuclearwinter on Skaro.
I missed the first episode, watched the second from behind the sofa.

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

#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.

Missing that nuclear winter yet?

@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!"

* 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!

Nowhere to hide: How a nuclear war would kill you — and almost everyone else.

October 20, 2022
By François Diaz-Maurin

"Since Russia’s war in Ukraine started, President #Putin and other Russian officials have made repeated nuclear threats, in an apparent attempt to deter Western countries from any direct military intervention. If Russia were to ever start—voluntarily or accidentally—nuclear war with the United States and other NATO countries, the number of devastating nuclear explosions involved in a full exchange 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.

"Stratospheric soot injections associated with different nuclear war scenarios would lead to a wide variety of major climatic and biogeochemical changes, including transformations of the atmosphere, oceans, and land. Such global climate changes will be more long-lasting than previously thought because models of the 1980s did not adequately represent the stratospheric plume rise. It is now understood that soot from nuclear #firestorms would rise much higher into the stratosphere than once imagined, where soot removal mechanisms in the form of 'black rains' are slow. Once the smoke is heated by sunlight it can self-loft to altitudes as high as 80 kilometers (50 miles), penetrating the mesosphere."

#FACTCHECK:

This program upgrades old #Nuclear Fission #warheads into newer Nuclear Fusion warheads, and generally maintains the current arsenal. It does NOT increase the supply of #NuclearWeapons, and newer Fusion warheads actually have FAR LESS #NuclearFallout than the old ones: this decreases the risk of #civilian exposure to nuclear elements, and #NuclearWinter.

This is an alternative to #Putin attempting to fire a #missile recently which malfunctioned and destroyed the entire launch site.

While nuclear weapons are a dangerous thing to have, and preferably should NEVER be used, #NATO keeps a supply for retaliatory purposes: Russia alone has more nuclear weapons than all of NATO combined.

NATO's nuclear weapons are only usable in specific, retaliatory and existential circumstances, such as a full-scale nuclear first-strike by Putin.

Either way, as having nuclear weapons is neither new nor exclusively #US policy, the claim that it increases the likelihood of #NuclearWar is FALSE.

Se avremo una apocalisse nucleare, il vostro nazionalismo, l’oscena esaltazione bellica, gli attacchi alla sfera politica che potenziano quella militare, la cieca corsa al riarmo di un blocco che ha già abbastanza armi da distruggere più volte il pianeta, passeranno alla storia come il contributo occidentale all’escalation che ha seppellito l’Europa e il mondo sotto il #nuclearwinter.

E le vittime dell’ultima guerra mondiale vi malediranno e odieranno quanto Putin.

If VEI 8 is reached, apart from human and ecological disaster in🇮🇹#Italy, we will face a #NuclearWinter.Fortunately, the last eruption released 285 km3, far from 1,000 km3.

"We find seaweed can be grown in tropical oceans, even after nuclear war. The simulated growth is high enough to allow a scale up to an equivalent of 45% of the global human food demand (spread among food, animal feed, and biofuels) in around 9–14 months, while only using a small fraction of the global ocean area."

Let's not go there.

#Neoliberalism decreases trust in scientific findings. Human caused events need #Regulations to not be harmful for us and the #Environment. However, the idea of neoliberalism is to have a small, non interfering #Government. This often has lead to neoliberal governments ignoring, defunding and even distorting #Science. In my newest post on #ExistentialCrunch I explore the history of this #ScienceDenial and how it relates to #ClimateChange and #NuclearWinter. https://existentialcrunch.substack.com/p/science-denial-and-nuclear-winter

"...atmospheric scientists Paul Crutzen and John Birks (in 1982) suggested a nuclear war would produce a [massive] smoke cloud [causing]...a nuclear winter [which] would devastate agriculture and...civilization."
https://phys.org/news/2023-08-nuclear-war-devastating-earth-climate.html

"With the largest possible nuclear exchange...new models suggest... that the world would be thrust into a "nuclear little ice age" lasting thousands of years."

"A global nuclear war...could result in 360M people dead and [starve] 5.3B people" #NuclearWinter

Today I'm as #optimistic as in "Don't worry about #GlobalWarming, it will be fixed with the #NuclearWinter that will come right after a #NuclearWar".
