What if the World Ended?


There is no denying that the shadow of the atom bomb has been across all our lives. Vsauce, it is good to see you. Here just let me take this off real quick…gotta protect yourself from the UV rays. …it’s Jake,
remember, we were together in Could You Survive a Fallout. No worries, it’s fine, I’ll
put a link to that video down in the description. Huh, here I am talking like YouTube, let alone the internet is still a thing. But at least we survived the fallout…so we could live
in this. You know what’s happening out there right? Ah, don’t worry I’ll fill you in. They
say war is hell, but that doesn’t mean the aftermath is any better. I need a can opener. Do you have a can opener? Lets get a can opener! Now, we know the effects of nuclear fallout
but let’s consider something, which won’t be hard given what we’ve been through: a
relatively small nuclear war breaks out between two large countries, 100 nukes are dropped,
less than 1% that exist…20 million people would immediately die. BOOM – gone. And that
sounds like a lot, but in the grand scheme of things 20 million deaths, or 20 Megadeaths,
is only .3% of Earth’s population. But something worse happens. And it isn’t
the bombs, it isn’t the fallout, it’s what’s left for the over 99% of the population
that survives…what we are experiencing right now…Nuclear Winter. Nuclear Winter is a fairly recent term, having
been coined about 34 years ago. In the early 1980s, a team of scientists were assembled:
Turco, Toon, Ackerman, Pollack and Sagan. Together they wrote the scientific paper “Global
Atmospheric Consequences of Nuclear War”. And they discovered that nuclear war might
be devastating, but the shadow it casts is much larger, much more suffocating. Imagine entire cities in flames, hundred of
thousands of buildings, factories, parks and forests burning. All that smoke is heated
by the sun, lofted into the upper stratosphere, and the particles would blanket the Earth.
I’d love to give you an uplifting fact right now, some ray of sunshine, but unfortunately
all that soot would block enough sunlight that skies would be overcast, everywhere,
for a long time. And that’s just the start. Obviously, a lot of this research was based
on climate models because the only way to test this theory in the real world would involve
actually creating a Nuclear Winter and we know how well that turned out…but there
have been events in the past that were used to help determine what would happen. And one
of them was 140,000,000 miles away. In 1971, the U.S. Mariner 9 spacecraft, the
first vehicle to orbit another planet, arrived at Mars to find it completely covered in a
global dust storm. What scientists discovered was the dust had been brought high into the
atmosphere, absorbing the sunlight and preventing a lot of it from hitting the surface. This
brought the surface temperature down tens of degrees (put in F). But that happened far away on a completely
different planet, so it is hard to try and imagine temperatures dropping so drastically
here because of something as small as dust blocking out sunlight. Except we don’t have
to imagine, nor did researchers, because it had happened before …over 200 years ago. The Tambora volcano erupted in 1815 in Indonesia.
That eruption blotted out the sun and produced global cooling of about 0.5 degree C for a
year. Half a degree seems pretty insignificant…but it wasn’t. 1816 was called the “The Year
without a Summer” or “Eighteen Hundred and Froze to Death.” In New England, frosts
happened every month killing the crops, and this was during the summer. The price of grain
shot up, and with that farmers tried selling all of their livestock since they could no
longer feed them, and a mass migration began to the Midwest of America to flee the effects
of the temperature change. In Europe the stock market collapsed and widespread famine occurred. Using that information, they were able to
conclude what would happen but that study was done at the height of the Cold War when
a full on global Nuclear War was much more of a threat. Remember when I asked you to
consider an attack with 100 nukes? Well that would be a lot more likely and a lot more
relevant to our current situation so, in 2009, researchers used the original report as a
framework and estimated the effects of a war that used 100 nukes the size of Hiroshima’s.
Even with that relatively small number, it would still be globally devastating and it
all starts with tiny particles. At least 5 Teragrams, about 11 billion pounds,
of smoke would be produced because of the fires started by the bombs. Within two days
those tiny particles would rise 7.5 miles into our Troposphere. The sun would heat them
up and they would continue to rise. After 49 days the smoke would reach a height of
31 miles and fill the Stratosphere. By this point, the soot would cover the majority of
the planet, blocking sunlight and making the skies overcast. Unfortunately, precipitation never reaches
the stratosphere so the particles wouldn’t be washed away. And speaking of precipitation,
there would be a 10% decrease of it worldwide since the lack of sun would cause problems
with evaporation and the natural water cycle. Taking what we learned from Mars and from
the Tambora volcano, the sunlight being blocked would drop global temperatures by 1.25 degrees
C. The cold and lack of sunlight would obviously be bad for agriculture, with crops and farm
animals dying off. But something else would also be devastating to that…ultraviolet
radiation. Even though the surface of the Earth would
be colder, the black smoke in the stratosphere would absorb the sunlight, heating it up by
more than 50 degrees C. Because of that, nitrogen oxides would be lofted further up, destroying
our ozone. Over 17 months we’d go from this, to this. Not only would the UV radiation be incredibly
damaging to plant life but it is incredibly damaging to us. I’m not wearing this many
layers and covering my skin just for fun. It would take as little as 6 minutes for me
to get severely burned outside because of exposure. Which is why I need a can opener…I
mean, not because of the sunburns but because there are no crops, there are no fresh foods.
Only cans. There is enough grain stored to feed the planet’s population for 2 months.
After that…1 billion people could starve to death. 1 billion. Over 13% of everyone
alive just… This reminds me of poet T.S Eliot’s The
Hollow Men, “This is the way the world ends, not with a bang but a whimper.” After 10 years the cloud would be lifted,
the soot would have finally fallen from above and temperatures would start to rise. And
what would be left of us? You could call it the end of the world. You could say all hope
is lost. Or you could say something else… Where we stand is not destroyed, we are not
in ruins but in something waiting to be built. Waiting to begin again. From these ashes we
can rise and create beauty. The crumbling walls are not a representation of our failures
but a reminder of the lessons we have learned. So we continue on. Not because we want to
but because we have to. In the words of Carl Sagan:
“A new consciousness is developing which sees the earth as a single organism and recognizes
that an organism at war with itself is doomed. One of the great revelations of the age of
space exploration is the image of the earth finite and lonely. We are one planet.” And,
as always, thanks for watching.

  2. Tambora explosion was indeed terrifying, nearly 100% of Sumbawanese and middle Indonesian (Sumbawa is where Tambora located, middle Indonesia, and Sumbawa is also my hometown though) burried alive and killed, and the effect affected the planet as well..

  3. I watched this video 2 years ago
    I really wish that some Indians who are asking for the war could see and understand this video

  4. those who die by the first shot of war is truly fortune, for they know not the agony of the aftermath of war

  5. Detonating a Nuclear Bomb to win a war is like trying to win a game show by killing the Audience..Its madness it is truly M.A.D

  6. If the bombs fell, you would see me wandering the wastes, trying to trade for bottlecaps, and shooting ghouls/muties in their faces with a trusty hunting rifle.

  7. I was playing xbox around a week ago and someone told me, “a long time ago a prediction was made. Everything is adding up, something very bad is coming to America for the next couple months and years. God bless you and your family, stay safe.” And know I’m really freaked out

  8. 1:10 – how, and I mean how, did you not use the phrasing "war…war never changes" at this point. This is such a missed opportunity it hurts me.

  9. Oh god I hope it happens. Let's see what happens….it is only the possible extinction of humans. My guess is a billion will survive, unfortunately.

  10. The likes of Trump would love that, wouldn't they? Get rid of all the poor people and pretend global warming isn't happening for another 10 years. Expect them to start harping on about "overpopulation" soon, that's how it begins…

  11. If you're still alive, the world didn't end yet. . .it maybe just became more difficult to live, that's all.
    As long as your mutant kids still have a chance of breeding healthy kids several generations down the road, you're doing fine.

  12. well,im not planning to end it yet as there are me and my people still on the planet….also resources

  13. "Where we stand is not destroyed, we're not in ruins, but in something waiting to be built, waiting to begin again. From these ashes we can raise and create beauty. The crumbling walls are not a representation of our failures, but a reminder of the lessons we've learned. So we continue on, not because we want to, but because we have to."

  14. yep. this is the video that got me into the 80's aesthetic and vhs video creation. i have a vhs camcorder and after messing with it i realized how accurate the vhs effect is. also unlike the obsolete geek jake actually adjusted his tracking

  15. Nuclear winter, unlike human-made climate change, is not settled science. There needs to be a considerable study on the amount, height, type and timing of materials that would come from (a very very bad euphemism) the targets. Many of the cities studied regarding the formation of firestorms were from World War 2 where construction was considerably different from today. These studies just assume as a starting point, a certain amount and type of material will be in the atmosphere and then start their calculations using their atmospheric models.
