Can anyone tell me as much as they can about a nuclear winter?

Question

like how long it is, how it can start, a way to survive, the environmentall change and anything else you could think of....

Answer 1

IT'S THE THIRD FAZE OF A NUCLEAR FALL OUT  WHERE EVERY THING  DIE MEN WOMEN PLANTS AND ANIMALS I  SEEN A DOCUMENTARY ON THIS AND THEY SAY A NUCLEAR WINTER COULD LAST FOR SEVERAL YEARS

Answer 2

nobody knows for sure. anybody that says they do is wrong. the theory is that if there were mutual annihilation by nuclear weaopns it would block the sun out from the Earth. it could be 1 year. 3 years. 100,000 years nobody knows until we are actually stupid enough to try to find out.  Let us all hope humanity never has to find out!

Answer 3

A flawed idea created by scientists, such as the late Carl Sagan, that a nuclear war would result in blocking sunlight and creating a world-wide cooling of the planet. Basically a way to get the West to disarm, this idea was based on the thought that ALL nuclear weapons owned by every country would be used at the same time and ALL would be ground-bursts, as opposed to air-bursts (the best way to take out "soft" targets such as metropolitan areas and large industrial sites.) Ground bursts would put large amounts of garbage into the atmosphere since the central fireball scoops out a large crater, later returning to earth as fallout. This type of weapon would normally be used to destroy underground targets such as missile silos, command and control facilities, etc. Air bursts, such as used on Hiroshima and Nagasaki, result in relatively small amounts of fallout since the central fireball doesn't normally touch the ground. Since weapons and tactics are based on the types of targets to be destroyed and the country being targeted, any "nuclear winter" effects would most likely be a localized event rather than a global event. Just my brief .02 worth.

tons... & tons of info on it right their.

Answer 5

The people living in tropical regions would probably survive a nuclear winter. The temperature drop is estimated at 50 degrees Fahrenheit in that region. In an area that regularly sees temperatures of 100 degrees Fahrenheit in summer there would be a short growing season. The real problem is a nuclear summer, which may occur immediately after the nuclear winter. The Earth will keep heating and heating until it is too hot for any life to survive.

Answer 6

While Nuclear winter is a theoretical concept, it is not a flawed idea. In short, many scientists, other than the late Carl Sagan) believe that a large scale nuclear war would change the global climate in great proportion.

Most scientists agree that a full scale nuclear exchange would likely catapult large amounts of soot and smoke (aerosal particles) into the Earth's stratosphere. Along with this, the ash and dust ( which could settle in the stratosphere for months or even years ) would likely travel by wind over a great distance to create a wall between the Earth and sun.  While it may not take as little as 100 megatons of detonations as Sagan projected, the idea of a nuclear winter would impact the biosphere if a full scale exchange took place.

While nuclear winter may not wipe out life on earth as the early computer models suggested, it will have global climatic impact.  Most likely it will speed up the global climatic change that we're already experiencing without the help of nuclear detonations.

As far as surviving in prolonged cold, look to the example of our northerners in Alaska and Canada, how do they survive in cold weather for most of the year... alot of common sense would be needed, but that's just my opinion.

Answer 7

A nuclear winter is caused by a numerous amount of nuclear bombs detonating and spewing contaminants into the atmosphere and it blocks the sun for up to 2 years killing all vegitation and animals. To survive you need a shelter underground radiation proof with supplies for at least 2 years. The environmental change would turn everything we know into poison and deadly everything,even if you lived you wish you wouldn't have.

Answer 8

Nuclear Winter is a failed environmental theory from the 1980s.

The theory was that the amount of smoke produced by fires in urban areas would block enough sunlight to reduce global temperatures.  This theory had several problems.  Not only did it assume that both the US and USSR would use nonsensical strategies (wasting nuclear missiles on cities that are irrelevant from a strategic standpoint) but the predictions made by the theory were shown to be wrong when the effects from the Kuwait oil fires after the first Gulf war were several orders of magnitude less than the theory predicted.
