As discussed briefly in Nuclear War Survival Skills, which also came from Oak Ridge, the real trick is food starting not long after the event, but it's not that difficult.
The summary [1] is worth reading. Apart from protecting against fallout radiation exposure, the most urgent need is transportation, to deliver food.
<excerpt>
... the location of people as planned with the current program and the location of grain stocks indicates a possibility that millions may perish from food shortages unless food shipments are begun within two or three weeks after the attack.
Sufficient grain to feed the entire population of the U.S. for several months to more than a year, depending on the season, exists in storage in the local areas where it is produced.
When the quantity of grain in storage is less than a year's supply, there is adequate grain growing in the fields, much of which can be harvested with little radiation hazard to agricultural workers if appropriate precautions are taken.
If the attack occurs in June, when crops are on the average most vulnerable to fallout radiation, about one-third to one-half of the annual crop yield could be destroyed. Additional crop failure could occur due to increased ultraviolet radiation resulting from depletion of the ozone layer. ...
Citizens' Band radios will probably survive in numbers adequate for critical civilian communications e In 1973, there were approximately 4 million CB transmitters in the U.S., and this number may double by 1977.
Shipment of food and other crucial supplies wi.11 use primarily trucks and trains, of which at least 60% may be expected to survive because of relocation measures taken during the crisis period. Ships and barges may not be very useful in the first few weeks after the attack because of fallen bridges and destroyed locks and docks, although the vessels themselves may survive because of crisis period action.
Oil pipeline terminals will be damaged or destroyed in crucial locations, and most of the refineries will be destroyed. However, about two billion gallons of diesel and about three billion gallons of gasoline would survive in tank storage outside of the major risk areas, which would be more than adequate for the trains and trucks to carry out survival missions during the first few weeks after the attack.
At least 20 million gallons of aircraft fuel will survive in tanks at lesser airports, which may be available to light aircraft of the Civil Air Patrol. First priorities should be given for reconnaissance of transportation routes, surveying blockages by debris and fallen bridges, and monitoring radiological hazard with aerial survey meters.
Very few large interconnected power plants are expected to be operating in the first few weeks after an attack because of disruption of the transmission grid by blast and fire. It is anticipated that electrical power will not be essential :for basic survival in the first few weeks after the attack and will gradually be restored during the recovery period.
A lot has changed in 50years. Number, size, accuracy of weapon impacts. Farming's reliance on mechanization, pesticides, fertilizer. Way more food is manufactured/processed. How many people even know what to do with a sack of flour and a firepit. Transportation changes, trucking vs rail. I'm not sure but the general push for efficiency, JIT warehousing, I wonder if our food stocks on hand is the same. Also, I'm guessing the fall of USSR, rise of Terrorism as new bugaboo. I wonder how much study, effort, and prepardness USA government has put into full scale nuclear war "defense" of late.
Well, we're also turning a substantial fraction of our corn output into ethanol to burn for fuel. Stop that, and the feed used for animals, factor in a much reduced population, and the numbers probably work out.
How many people even know what to do with a sack of flour and a firepit.
That's where things start getting really sticky. Nuclear War Survival Skills has a simple design for a pestle made out of three pipes bound together, in this scenario people are not likely to get anything as refined as flour. Then boil it into porridge.
If you get fallout into my sough dough starter I'm going to to be pissed. There is a small amount of evidence that brewers yeast may be helpful - mostly from sites like the link below.
Simultaneously awful design and alarming advice. Check these highlights.
"Apple Pectin Capsules
This can force strontium through the body, without its being absorbed.
Sunflower Seeds
Eat for radiaiton[sic] poisoning. Source of pectin to attract, bind and eliminate radiation from the system."
This is really interesting, but if I was planning a nuclear attack on a country, I would attack twice: once for the initial effect and secondly to take out whatever support is built in its aftermath, which is what this document talks about building.
I don't see this report tackling that. They assume only one large-scale attack.
Doing that would require both serious reconnaissance to know where to attack, and enough weapons surviving our counter-stroke. And of course we could play the same game, or at least continue hunting and knocking out their weapons.
The study has to make some simplifying assumptions, and you could evolve it yourself by assuming some fraction of those surviving get zapped in due course. But not likely all.
The plan was, though, to put us down for good, Western Europe was the prize, the US an obstacle to taking it, and too far away to seriously occupy and extract value from.
You assume that you're not retaliated against. This is the essence of MAD, a kind of bizarre gentleman's agreement. The general opinion was that as soon as the nukes start flying, you can pretty much assume that your country is going to get decimated as well. When you nuke someone, there's a good chance they'll do exactly the same to you. Both sides planned for automatic counter strikes even in the event that the command chain was broken, though whether the capability was actually there is uncertain.
Not to mention that you will probably have allies. There is a good chance that if Russia had bombed the US, most of NATO would have turned on Russia. The Cold War wasn't exactly peacetime, but it wasn't open war either. An act of such extreme aggression as a nuclear strike would have had far-reaching consequences. You wouldn't have been able to sit on your hands, waiting for the person you bombed to set up the field hospitals before bombing them again.
On the other hand if you'd just nuked a superpower, you'd have started a world war. Odds are you're going to go back and bomb them some more anyway, and they're going to try and bomb you back.
It's true though, these reports tend to assume that a nuclear strike is the end of the conflict rather than the start of a protracted war. Although maybe they tend to focus on the civilian side and assume that the military is going to be off doing its thing.
The TTAPS study is bullshit (more details on request); if you do thorough 3D atmospheric simulations, as was done later at LLNL, you get at worst a season or two of cooler temperatures, but hardly the end of the world.
And I wouldn't really characterize the following period as "a bit more serious about arms reduction", compared to the glory days of détente in the '70s. All you really have for that period is the Intermediate-Range Nuclear Forces Treaty, which returned Europe to the situation before the USSR started deploying SS-20s in major quantities (per Wikipedia, eventually 405, each with 3 MIRVed warheads). After that, it's START I, which was signed a few months before the USSR dissolved at the end of 1991.
There are known global climate impacts linked to single volcanic events e.g. Tambora in the 19th century, Krakatoa, etc.
"All" you have is START 1, which resulted in an 80% reduction of nuclear weapons. In addition there was a fair amount of behind the scenes assistance from the US in helping clean up the somewhat precipitous situation the USSR left itself in with the nuclear weapons - granted they started removing them months before the collapse.
The public debate changed subtly after that report. The folks arguing - as you appear to be - that a nuclear war wouldn't be that big a deal, got a lot quieter.
"I’m not afraid of nuclear war. There are 2.7 billion people in the world; it doesn’t matter if some are killed. China has a population of 600 million; even if half of them are killed, there are still 300 million people left." Mao Tse Tung, 1957
In short, the study uses a 1 dimensional model of the atmosphere, a particle of soot can go up or down, but there are no winds, no oceans, etc. These models are said to be especially prone to failing hard when given extreme inputs, and the second part is the soot they claimed would be lofted into the air, sizes and quantities, which they did not justify, or justify well (can't remember, it's been decades since I read the paper).
Their excuse for using such a model was a lack of computing resources, and they were indeed dear back then. But that made their running a massive propaganda campaign based on this inadequate at best "science" all the worse.
Anyway, LLNL, which had serious supercomputer resources for designing nuclear warheads and such, ran 3D simulations with more plausible inputs, and indeed found effects were possible, but they weren't a big deal. Certainly not on the scale of some of the bigger volcanic events. (It's a bit arrogant to automatically humans are so capable of changing the earth that much, especially that quickly; compare, as you do, to events like Tambora.)
The folks arguing - as you appear to be - that a nuclear war wouldn't be that big a deal, got a lot quieter.
Not that I noticed. Especially since we never argued that, only that it wouldn't be "the end of the world". Maybe we just got more thoroughly ignored by the media, after all, the sainted Carl Sagan was wielding SCIENCE! and we were nobodies. Note Sagan and Turco of the TTAPS team should have been a little more modest when the prospect of Kuwait's oil wells getting set on fire in the first Gulf War came up, their theorizing did not match the reality to soon follow.
Of course, to the extent this might be an issue (and even modest effects would be less than welcome in the aftermath of a major nuclear exchange), it made SDI/BMD all the more important, to prevent city busting in the first place....
I go two ways on that one. As you point out, on the one hand it is hard to beat Mother Earth when it comes to massive climate impacts, up to and including two eras where the world was a complete snowball, and multiple wipe out of anything bigger than a rodent by asteroids. On the other, the Russians got up to 50Megatons before the test ban treaty kicked in - and while you may wish to argue that a few of those flying around wouldn't be the end of the world - I on the other hand would wonder what would happen if some evil bastard targeted the north pole/greenland with them, thereby changing the albedo of the entire planet. (Yes, I know you couldn't melt the entire glacier, but dump enough soot on it, and I wouldn't want to predict the short term consequences.)
I agree the Gulf War thing was entertaining for anybody paying attention. It is more than a little irritating that in so many areas of science, there's no follow-up on prophecies like that. Some kind of this day last year, X predicted Y, which didn't happen would make a fun end of the news item.
If they didn't care about fallout, the Tsar Bomba would have had probably twice the yield, by substituting depleted uranium for the lead or whatever that was used for the fusion tampers.
What I've read is that, aside from bragging rights, and the occasional extremely hard target like Cheyenne Mountain Complex, somewhere slightly above 1 Mt you reach diminishing returns, because more and more of the energy released radiates out into space (note how "small" the normal size of nuclear warheads is nowadays, several hundred Kt times many and more accurately targeted warheads is generally the way to go). But there's fortunately a lot we don't know about would be planet-busters, so let's not find out any time soon....
As for melting lots of water, you'd probably be better off with the Antarctic ice pack, per Wikipedia it's a order of magnitude larger, or 58 meters of ocean rising vs. a much more manageable 7.2.
Dumping soot on any of these would take a trick or three, since nuclear warheads are, if anything, I'm pretty sure way too energetic to directly do the chemistry, but I haven't really thought about it yet. You'd need to create soot upwind, which might be possible for Greenland, but wouldn't it be a trick for either pole?
As for directly, if http://www.onlineconversion.com and my use of it is correct, 50 or even 100 Mt, perfectly applied to a cubic mile of ice, wouldn't even come close to melting it, you'd need more than 334 Mt. Mt -> joules and cubic mile -> cubic centimeters are astonishing close to equal, like within 0.4%, and 334 joules are required to convert a cubic centimeter at 0C to water at the same temperature, you got to love hydrogen bonding.
Yeah, the Earth is big, and we're pretty puny. If only the bi-coastals who fly over fly-over country were inclined to do math when they looked down....
Salted bombs have always been the weapon of choice for evil bastards who wanted extinction level events. Salted bombs are designed to maximize radioactive fallout and render an area uninhabitable for 20+ years by "salting the earth" so to speak.
Salted bombs were considered for use as a deterrent and were speculate to be the doomsday weapons that was central to the plot in Dr. Strangelove due to the potential to wipe out all terrestrial life on the planet bigger than a rabbit. Smaller devices were also considers as a method to permanently close an choke point to invading troops such as the Fulda gap. Russia "leaked" plans last year for a drone controlled submarine that carried a large salted (cobalt) bomb which would surface at a port and depopulate anything down wind.
I had a friend in college who's Dad worked who helped test or design nuclear weapons. I guess the minimum number of weapons required for an extinction level event had been calculated at some point. The weapons would need to be positioned correctly but eight salted weapons were the minimum needed for an extinction level event. My friend said her Dad was always proud that he knew the exact number.
We've had the capability to wipe humanity off the planet since the late 50's. Kind of warms your heart that we haven't done so.
Slightly off topic: I'll have to dig it out - they started making the casing (I think, or whatever the outer shell is called) of SS-20s into tourist tat which you could pick up in the 80s and 90s. I have a badge and some other stuff made of it I picked up somewhere.
The report seems to rely on the then-widespread usage of CB radios to preserve post-attack civilian communications, but that technology seems to have largely been abandoned except by truckers.
Would we have a harder time today in a post-attack scenario maintaining communications as compared to the late 1970s and the CB craze?
That's a question that I'm pretty fascinated with personally. When it comes to communications after a major disaster, we continue to plan to rely primarily on 'conventional' radio via e.g. clear-channel AM radio stations and other major commercial broadcasters which have worked with the government to prepare solid contingency plans. For this reason, it's a good idea to own a portable radio or two even though you wouldn't normally use them, and to familiarize yourself with an AM news station (e.g. KCBS 740 KHz in the bay area).
Of course, for two-way communication we are all quite dependent on our cellphones. The cellular networks own mobile equipment and other provisions for providing service in a contingency situation, and ideally there could be no interruption in service (as the generators at many cell sites could hold them until service crews arrive, in the case of loss of electricity, for example). But in practice it's easy to imagine a few scenarios that would have the cellular network significantly deteriorated in a region for days, such as a major earthquake that damaged infrastructure and made it difficult to get equipment and fuel to the area. In the short term, I wouldn't count on it. In the long term, the effort involved in restoring cellular service could be enormous but it would be a reasonably high priority.
It'd be a good idea for more people to own accessible point-to-point radio equipment with a decent range. I don't know how to achieve this though. CB equipment is bulky and now relegated to its own particular subculture. The amateur radio industry has produced a lot of high-quality handhelds but they're designed to be the opposite of accessible. There have been some ideas based on peer-to-peer relay between mobile phones but the range remains very limited. Maybe someone could come up with a good product in this space.
Back then they could wave their hands and correctly say there were so many CB radios they'd be enough for post-attack civilian communications, at least at shorter ranges.
But that doesn't mean you couldn't get by with many fewer working radios, and FRS and GMRS equipment is out there in some quantities, in addition to hams, many of whom are set up for emergency communications
And as noted by jcrawfordor cell phones are a zillion times more ubiquitous than CB radio sets ever were. In fact, noting the pattern that many less developed 3rd World counties leapfrogged over land lines straight into cell service, following that pattern in the rebuilding would probably work out pretty well.
ADDED: and WiFi equipment is also ubiquitous, and with directional antenna can travel pretty far. So we'll have quite a bit of stuff to work with, and people are pretty good at cobbling together solutions for problems like this.

A few do. And she/he would have some very motivated students :-)
Otherwise, yes, it's kind of fuzzy mapping the situation of the early 70s to the current day.

I suppose food reserves for the year have to still be somewhere between harvests, but industrial supplies like fuel? No idea.
It may be that food reserves are elsewhere in the world, which is why I can have blueberries on any day of the year.
I don't see this report tackling that. They assume only one large-scale attack.
