(AP)  American scientists have determined that a regional nuclear war would put the world in havoc for at least a decade by shredding large areas of Earth's protective ozone layer.

The countries involved would be devastated as well as fall victim to the ozone disaster, the scientists' analysis says.

Massive fires resulting from even a limited conflict would blast enough soot into the atmosphere to create an ozone hole over heavily populated areas, the researchers warned in a paper published Monday in the online edition of Proceedings of the National Academy of Sciences.

A region of depleted ozone over the Antarctic, known as an ozone hole, has been a worry to scientists for years as it allows damaging ultraviolet radiation from the sun to reach Earth's surface. Some chemicals have been banned from use to help eliminate that hole.

Unlike the Antarctic, a nuclear-induced ozone hole would affect much of the world, causing damage to plants and animals and adding to skin cancer, eye damage and other effects in millions of people, according to researchers led by Michael J. Mills of the University of Colorado.

Mills' team used complex computer programs to model what would happen in the atmosphere in the event of a war between India and Pakistan in which each detonated 50 Hiroshima-sized nuclear explosives.

They calculated that the blasts would send as much as five million metric tons of soot as high as 50 miles into the atmosphere.

The soot and the heat from solar radiation would cause a series of chemical reactions that would break down the stratospheric ozone layer that protects Earth from harmful ultraviolet radiation, they said.

"We would see a dramatic drop in ozone levels that would persist for many years," Mills said in a statement. "At mid-latitudes the ozone decrease would be up to 40 percent, which could have huge effects on human health and on terrestrial, aquatic and marine ecosystems."

They calculated that a 40 percent ozone decrease would result in a 132 percent increase in light damage to plants and a 213 percent increase in DNA damage associated with skin cancer.

The mid-latitudes are the regions between the tropics and the Arctic and are home to the largest numbers of people.

Well, let''s have one then.

We''ve been angling for Israel to have a nuclear confrontation with Iran for years now (or has Israel been angling for it? either way, no matter). And we already have a well-establish global warming denying infrastructure in place as well as the requisite sociopaths in power to do it.

Genocide AND global environmental damage - it''s a conservative Republican wet dream. They''ll do it just to show the CAN, that''s how perverse these nutjobs are.

Seems like the US, USSR, China, France, UK have done enough atmospheric testing from 1945-1975 (or so) to either prove or disprove this theory... assuming that someone was monitoring the atmosphere. Those were some pretty big bombs in the 1950s and 1960s (when poor guidance systems were compensated with large yields), but we''re still here.

Coppertone save us!!!

Yes, both the US and the former USSR did a large number of above ground testing in the early days.Fortunately (to use the term loosely) they were done over either ocean or in desert areas where there weren''t a whole lot of flammable things (trees, plants, houses, people.) Its the resultant ashes from burned life forms which will cause the destruction of the ozone, not the kilotonnage or megatonnage of the explosive devices themselves.

My god environmental scientist say the dumbest things. If the sky is filled with soot do you need an ozone layer? No. Why do they never tell you how Ozone is made? Well its made from the interaction of UV light with oxygen. So if you have a hole and more UV light gets through to the oxygen it makes more ozone and pluggs the hole. As if nuclear war wasn''t enough deterant.

connapa, that makes sense. I guess most of those tests were in places like the Bikini atoll... and I guess events like Hiroshima and Nagasaki the Japanese wouldn''t have cooperated with an effort to monitor the atmoshpere. Still, this prediction would be a lot more effective if there were some such proof.

I fear that one day in our lifetimes we will have our proof (India/Pakistan, Iran/Israel, North Korea/??).

It is easy to call something dumb when you do not have the education to understand it. I will try to keep this simple.
The soot in the sky would block the visible light to some extent, but would do little to block the UV. Certain frequencies of light can penetrate one material easily and not be able to pass through another. So a sky of soot with no ozone would pass UV down to the ground. Yes, more UV in the lower atmosphere would mean more ozone created, but the old ozone and new ozone react with the soot in the upper atmosphere and become other molecules that do not absorb UV. It would take a long time for the ozone to be restored.
It always shocks me how many people with a high school education think they know better than phds.

I suspect there is a much better chance that Israel will use nukes against Iran than there is of India duking it out with Pakistan. Israel has the big ones. Not the WWII style Iran is trying to build. And if someone is stupid enough to provoke Israel into using them, they might not stop until they''ve eliminated everyone that ever threatened them.

I thought of some examoples that might make this concept understanable to those of lesser education.
You should know you can get a sun burn on a cloudy day. That is because the UV passes through the cloud while the visible light is absorbed, just as it would be with the soot, except with more UV dud to no ozone.
Another example, consider three pairs of glasses. One is a clear pair of prescription lenses that has a UV coating. The lenses block most of the UV, but pass all the visible light. The second pair is sunglasses with a UV coating and the third pair is sunglasses with no UV coating. The second pair blocks most of the UV and most of the visible light, like the atmosphere on a cloudy day. The third pair blocks visible light, but passes the UV, like the atmosphere with no ozone and lots of soot.
The point of all this is that a regional nuclear war (say India and Pakistan for example) may have severe consequences all over the world. So we have an added incentive to try to avoid such a war.

True enough that I cannot spell very well. I think Mark Twain said something like it takes a very unimaginitive mind to think of only one way to spell something. I maintain it is the English language that is messed up, not me. I am systematic and logical. English uses spelling rules from many languages and has no reason to it. Any combination of vowels can have any pronunciation. I''m also a poor typist.
I have a BS in Physics and an MS in electrical engineering. I was explaining some concepts on absorbtion of UV and visible light. That does not mean that I accept this study is correct. But it cannot be dismissed simply because people like cbscrash07 do not understand that soot is not a good UV shield. Would exploding a few nuclear weapons really have a big effect on the environment? I say, we should not try that test. I do, on the other hand, believe that man would survive a global thermal nuclear war and nuclear winter. The few survivers could make green houses and use sun lamps and such. I also think that is an experiment we should not try.

Posted by HoosierMoon

You mean until WE''VE eliminated anyone who threatens them. Israel doesn''t have the resources to "eliminate" anyone without our support. Again it''s an open question of whether we''re driving Israel''s agenda or they''re driving our - but we seem to be unable to separate their interests from our.

And no one is provoking Israel, unless you define provocation or arming in self-defense as simply existing.

Any news related to science, facts, reality, ozone layer or war is to them a sign of gay communism because it distracts them from preparing for their massive suicides and the rapture that will take place in their child molseting compounds.

Scientists have stated that even a "small" nuclear war (how do you define "small" when it comes to a nuclear war?) will destroy the ozone layer for at least a decade or more.

The Great Emperor Bush and his older clone, John "The Great Prentender" McCain, together with every neocon Fascist Nazi out there, disregard these predictions as nothing more than a bunch of crazy scientists influenced by the evil, cowardly Whimpo-crats. Such "doomsday" predictions do not influence either the Great Emperor Bush II or "Bagdad John" in the slightest as both of them intend to go ahead with plans to create a new neocon empire, to be called "The Fourth Reich" and starting with Iraq and Afghanistan.

More countries which the Great Emperor believes belongs to him, will be added later, if not by him, then by "Bagdad John", when he takes over the throne in the Oval Office. It is assumed that the cowardly, stupid Whimpo-crats will have self-destructed by then and be of no consequence!

However, to be on the safe side, the Great Emperor has ordered NASA to push plans to improve the quality of their space suits, supposedly be developed for when astronauts of the USSA return to the moon (HA!) and move on to Mars (HA! HA!). The real purpose of the suits, however, is to protect those select neocon Fascist Nazis from being BROILED on THIS planet in the event the scientists are right!

SIG HEIL, BUSH!!!!

It''s like asking a fat person to only eat a couple of potato chips!
