I've studied nuclear war for 35 years -- you should be worried. | Brian Toon | TEDxMileHigh

  • Published on Jan 31, 2018
  • For the first time in decades, it's hard to ignore the threat of nuclear war. But as long as you're far from the blast, you're safe, right? Wrong. In this sobering talk, atmospheric scientist Brian Toon explains how even a small nuclear war could destroy all life on earth -- and what we can do to prevent it. A professor in the Department of Atmospheric and Oceanic Sciences at the University of Colorado-Boulder, Brian Toon investigates the causes of the ozone hole, how volcanic eruptions alter the climate, how ancient Mars had flowing rivers, and the environmental impacts of nuclear war. He contributed to the U.N.’s Nobel Peace Prize for climate change and holds numerous scientific awards, including two NASA medals for Exceptional Scientific Achievement. He is an avid woodworker. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx

    It is a good thing we had people like Stanislav Petrov. A man who may have saved the world in 1983.
    It was his job to report if there was an attack on USSR. The system reported an attack and he didnt report to supervisors, due to thinking it would be an error of the system and it turnend out, it was.
    The right man at the right place at the right time. Respect for this man.

      In the late 1970's, General Hartinger, called Loring Maine, to verify it was in exhistance when a test header on a computer disc pack had not been written correctly, that was a simulation, of inbound ICBM's for Cheyanne Mtn. (N.O.R.A.D.). Similar to "War Games",
      The movie. Many persons have shown great restraint from removing volumes of O2 and N2H3 from the atmosphere. Most flight officers are engineers and scientists, then political survivalists. Several have had to tell Mr. Trump, NO I won't do what you say it's an unlawful order. Familiarize yourself with the U.C.M.J. ( uniform code of military jurisprudence).

      I don’t really care about how many offspring one creates. I’m 71 and really don’t have a vote on what humans do. I have 2 children and only one crated 2 children. So that just replaces my wife and I. But I disagree that anyone has a right. I just agree to disagree. My father by the way was also in the navy and was in WWII. He is still alive at 101.

    We can all agree that the threat is great. Whether it is accidental or intentional makes little difference. We die just the same. Now, all we must do is convince our adversaries of the dangers. No small job. Then if we successfully achieve that we can turn our attention to the next danger. That chunk of rock with our name on it. We still face the same probability of demise as the dinosaurs. There's no end to the worry if we think about it enough. And... there is very little if anything we as individuals can do about it.

      Honestly, there is nothing you or I can do once the nuclear missles are launched. It’s hard to accept but I’d rather be taken out by the blast because surviving them and once the mushroom clouds have settled, you’re left with ashes and fallout. If the radiation doesn’t kill you then dehydration, malnutrition, or even psychological effects can go against you.

The flash from the H-bombs will be hundreds of times larger than what he shows. The blast shock wave will be hundreds of times larger, also. A good movie to see that shows what the H-bombs do, is, believe it or not, is War Games with Matthew Broderick. There are different scenarios that can trigger all out Global Thermo Nuclear war. When one missel launches, they all go up.

      @Abu Chai all religions are trying to point to salvation, maybe in different ways but still the flow is generally in the same direction. Fault here is everyone thinks they are right, from the subtle to the radical….different religions tend to argue and fight, even amongst themselves.
      Yet somehow, some way the mystics ALL talk about the same thing, from Sufi, Tibetan Monks, Christian Mystics, Hindi Advaita, Buddhist Monks, sages, gurus etc.. teach the inward path. A path devoid of the mind, a path of the heart. Until people can see, then lessons will continue to be taught through pain and suffering.

    My dad was an NCO in the USAF. We lived in a trailer park outside Moody AFB GA. The Cuban Crisis of 1962 is the closest we ever came to nuclear war. He was on stand by and sleeping at the hanger for 3 days. It was a Russian submarine commander who during the fog of war with no communication decided to 'stand down' and await to see if the USA had really launched before launching on Miami.... that's how close....

    Nothing he said s new, but likely new to people that don't ever think about these things. Saying we should do away with nuclear weapons is oversimplifying a very complex problem that statesmen have wrestled with for decades. Just how do you put the genie back in the bottle? Asking your congressman to do away with Launch On Warning without understanding the ramifications is also oversimplifying and dangerous. Doing something that sounds less threatening can actually have the opposite effect. Today the best protection we have against nuclear war is the knowledge both sides have that retaliation will be swift and certain, before the party being attacked will lose the ability to. History shows us time and time again that weakness (perceived or otherwise) triggers wars. Peace is kept through strength. It will be great when we have the technology to verify with certainty there are no more nukes. Until then it is what it is. MAD

      @Counter Culture Holy cow. That is super interesting and scary. Our house was built and a few years later they were about to convert it to a bomb shelter. It wouldn't do anything for that type of strike. I'm in automation and scratch my head at false alarms. That is a real head scratcher. Soviet mentality is evident today and probably the same for back then. Every once in a while a free mind is shown but definitely not rewarded. So sad. Ukraine already understands this. I think and hope the big ones are not used. I think they all understand this as end of civilization would happen.

      One man saved the world. Stanislav Petrov, a colonel in the Soviet Air Defense Forces, was instructed to tell his superiors if one of their early satellite warning systems had detected a nuclear attack. On the morning of Sep. 26, 1983 they had. The new system detected 5 nuclear missiles launched from the U.S. and were thought to be headed for Russia. It was later determined to be a false alarm due to an unusual alignment of high altitude clouds reflecting sunlight and ultimately signaled a catastrophic flaw in the new system design. Had Petrov reported the detected launch to his superiors, as he was ordered to do in case of such an event, the Soviets would have launched a massive nuclear counterstrike. Petrov held off in great anxiety because, for all he knew, the missiles could have been launched at the Soviet Union. However, he reasoned that because it was a new system and because it didn't make sense for the U.S. to just launch just 5 missiles (instead of a massive first strike) that he didn't want to be the man responsible for starting WWIII and causing the end of civilization. Petrov also noted that had some of his colleagues been on duty that morning they would have surely sent the notification to superiors because they were military men through and through. Stanislav credited his civilian training for making such a wise yet unconventional decision to not react. Petrov was never rewarded for his world saving decision. He died in 2017. You and your loved ones might want to send his two children a thank you card. We likely wouldn't be here if it weren't for him.

    The first school I attended was a 4 room stone school house in Baltimore County, Md. The school had a center hall with coat closets for each room. During the nuclear drills we would go into the coat closet and felt protected. The following year at the newly opened elementary school there were no coat closets. That’s when I found out that your desk would save your life.
    Half way thru the 2nd grade we were shown the effects of nuclear explosions. That’s when I realized why worry, if we are attacked, we lived 9miles from the city and 35 from DC, the end will be quick.

  • Diche Bach
    Diche Bach 2 months ago

    A great message, but of course there are many entanglements of reality for which it does not offer sound insights or suggestions.
    I for one would love to see all nuclear weapons and all human ability to build them *poof* instantly puffballed into non-existence. Of course, we all would; probably even the despots and tyrants who lead countries with existing nuclear arsenals would agree. But that is never going to happen. This is the key flaw with this approach to anti-nuke activism, too much focus on the fearful consequences and not enough consideration of real processes which might lead to the progressive reduction to lower levels and perhaps eventually to zero. But even in a world with "zero" nuclear weapons achieved by some amazing form of global consensus and shared interests, what would prevent someone in the future from rebuilding a nuclear weapon, perhaps even an arsenal?
    There are only two means for humanity to be relatively safe from the threat of nuclear Armageddon, one of which has been in effect for some 70 years, the other of which is what this speaker is hoping for and which realistically may take 1,000 years of cultural evolution to achieve, if not more.
    The latter, we might term "Mutual Shared Identity and Global Collectivism," the latter goes by the title of "Mutually Assured Destruction."
    IF humanity ever evolves to the point where there are no nations, no contentious ethnic divisions, no inter-group hatred, fear or hostility, and effectively no need for "military forces" beyond police, then this speaker's mission will be a real possibility and the entire world may indeed willingly decommission all its military weapons, including nukes. But I question if people who have not studied humanity closely really understand what all of that would really mean, or how problematic it might actually prove to be. In any event, it is some heady science fiction stuff, and I don't think it will be happening any time soon. Moreover, the steps to achieving it are not really promoted by harping about nuclear weapons, no matter how true all the points are.
    Mutually Assured Destruction on the other hand, is already doing its work and has been since sometime in the early 1950s. It does its work on the India-Pakistan border, it did its work to keep both the U.S. and U.S.S.R. from ever even considering the use of nukes in combat, and as long as leaders who control these weapons are always relatively sane and rational, it will continue to do its work conceivably forever. It is of course, not a perfect solution, it is indeed no "solution" at all, but merely an observed ecology of deterrence being exerted in two or more directions simultaneously. It is perhaps terrifying to realize that the only reason the world was not brought to an end already, decades ago in the 1960s or even the 1950s is fear, but such is the world as it really exists.
    While I agree with your assessments of the probably consequences of nuclear war, and I applaud your plea for 'better,' I also have to point out that, what you are calling for and apparently expecting is fantastic and very likely unrealistic. Still, Godspeed . . .

    "The end is nigh" Only madmen in power would threaten the planet because they are criminals.
    Ordinary people in every country on this planet deplore the actions of a few megalomaniacs.
    The quicker we get a one world goverment the better,without polititians but a group of planet
    caretakers. Sir David Attenborough has, through the decades has been telling all of us
    to look after the planet, but it seems to have fallen on deaf ears.

      are you overlooking human nature by any chance?? A "one world government" is essentially a brilliant idea to tackle "one world" problems like climate change and global food supply etc but it would undoubtedly attract egotists and narcissists who crave that kind of power............. i fear those kind of leaders would be even worse than the arseholes we have now

    From the perspective of a small, relatively insignificant country (New Zealand) resident in the South Pacific amongst a system and general populous seeming to act as though it is trying to be everything to everyone, It might all be a matter of space, compression and a larger numbers game. Perhaps masses around the globe might be considered "nuclear dispensable" by both pro and anti-capitalist, hawks and doves, as the enormity of population increase of human beings firmly sets in. Has anyone taken a closer look at David Harvey?

    Imagine what would happen if we weren't in constant competition with each other and we used this nuclear research to better understand and optimize energy through nuclear fusion/fission. Nuclear research is one of the most fascinating things in the world. And I honestly believe it is our path to reaching the next level of understanding our universe. It's sad that competition and money has driven this research so far off course. Crazy thought, what if everyone just worked together to advance our species, rather than focusing so hard on competing with each other. It's kinda pathetic really to think about how much more advanced we could be without the needless competition.

    "In retrospect, it seems completely logical that once a weapon is invented it will be used. But we forget the blindness and obsfucation of the late 20th and early 21st centuries, when the most destructive weapons were regarded as walls of protection, and when the horror of Armageddon was seen as a deterrent no sane society would risk. But the nations were not sane - rational, composed, aware, but not sane...the Death, when it came, was completely earnest and open. Every weapon was used as it had been designed to be used."

    A few points here. Nuclear weapons certainly are a scary thing, but it would be MUCH more scary if only the bad countries had them, and none of the good (or less bad) did. Mutual Assured Destruction has been the primary reason we've not turned the earth into a glass factory yet. What is truly the scary issue is considering the fanatics/extremists of the world. If someone is willing to blow themselves up just to kill or injure a dozen or so people, why would they care about the consequences from detonating a nuclear weapon?
    But, despite how scary nuclear weapons are, we still live in the best (not perfect) time in human history, especially in the west. Thousands of years ago you could step out of your cave and be eaten by a tiger, or killed by a rival over your dinner. Just a few hundred years ago you could die a horrible death from crapping your guts out after taking a drink of water or eating poorly prepared food. We're living longer and more comfortably than ever before thanks to medicine and technology. Despite how scary things may seem now, they always have been scary. Don't lose site of how fantastic things are, too.
    As long as their are bad people on the planet we'll have to retain these and other types of scary weapons. Unfortunately, there will always be bad people on the planet.
