If all atomic weapons in the world are exploded at a time, what are the chances of survival of Human Race?

Answer 1

Survival of the human race? About 100%. However, about 98% of humans would die in the first few years. That still leaves about 120 million, they would be mostly in the southern hemisphere. It would take about 150 or 200 years for the world to get back to today's population.

Answer 2

Actually quite good. Of the nations possessing nuclear weapons all are in the northern hemisphere. (note: South Africa may have built a weapon but it hasn't been proven. ) I don't think anybody has targeted Australia, New Zealand, Southern Africa or the nations of southern South America. Who would want to blow up Santiago Chile or Buenos Aires. The wind systems of the planet are pretty much separate above and below the equator. While there is some mixing the amounts of radioactivity reaching the southern hemisphere should be minimal. Increased cancer risk for a number of decades but thats about it. The Northern hemisphere would be pretty much toast, but the southern hemisphere would probably pull through fairly easily.

Answer 3

Absolutely zero. We and virtually, if not entirely all other life would be decimated.
They wouldn't even have to be spread out to cover the surface, even though we could. I do believe the current theory is, if even just 20 were detonated even just in the same place, the radioactive fallout world wide would be fatal.
Though that may be slightly inacurate, it is true that there is a limit to the number of atomic weapons that can be detonated before fallout will certainly kill us.

Answer 4

There was a myth pushed in the Cold War to try to avoid a nuclear war that we had enough nukes to kill the world several time over. It was not true. We could certainly devastate the population of the world, but people would live on in a far less habitable world and certainly cancer rates would skyrocket.

Answer 5

People can survive in space and under the sea for limited time.

Answer 6

the human race would not survive only roaches could live through something like that.

Answer 7

There may be survival! But it will no more be human.

Answer 8

pretty done deal. maybe some people in space might come back and repopulate...along with the inbred hillbillies who are so ingrained with white trash that they are immune. thats our future.

Answer 9

zero

Answer 10

zero
