Topic: Nuclear winter


  
  Nuclear winter
Nuclear winter is a hypothetical global climate condition that was predicted to be a possible outcome of a large-scale nuclear war.
It was thought that severely cold weather would be caused by detonating large numbers of nuclear weapons, especially over flammable targets such as cities, large amounts of smoke and soot[?] would be injected into the Earth's stratosphere.
One effort to predict the metereological effects of a large-scale nuclear war was the 1983 "TTAPS" study (from the initials of the last names of its authors, R.P. Turco, O.B. Toon, T.P. Ackerman, J.B. Pollack, and Carl Sagan).

 Nuclear winter: science and politics, by Brian Martin
Nuclear winter is an extremely complex area scientifically, laced with major uncertainties[77], and this allows a freer range of assumptions and interpretations than many other areas.
Nuclear winter is also an area which has considerable potential policy implications, and this means that the impact of 'politics' on the development of nuclear winter 'science' is likely to be much more apparent that in other, more esoteric, research fields.
Nuclear winter is a prime case of a challenge to traditional political elites -- whose power is rooted in established bureaucratic machinery -- by a group of outsiders whose demands are based on claims to special knowledge and expertise.

Nuclear winter creates the conditions of an ice age in the continental interiors in a matter of a few days.
The end of the Cold War, the fall of the Soviet Union, and a highly publicized attempt to discredit the 'theory' of nuclear winter by groups with a vested interest in preserving nuclear weapons: these events led to a decade of silence on the subject of nuclear winter.

 Carl Sagan / The Nuclear Winter
In "The Nuclear Winter" (1983), Sagan explored the unforeseen and devastating physical and chemical effects of even a small-scale nuclear war on the earth's biosphere and life on earth.
The amount of dust and soot generated depends on the conduct of the war, the yields of the weapons employed and the ratio of groundbursts to airbursts.
Scientists initially underestimated the effects of fallout, were amazed that nuclear explosions in space disabled distant satellites, had no idea that the fireballs from high-yield thermonuclear explosions could deplete the ozone layer and missed altogether the possible climatic effects of nuclear dust and smoke.

 Nuclear winter - Wikipedia, the free encyclopedia
In 1982 a special issue of the journal Ambio was devoted to the possible environmental consequences of nuclear war; it included an article by Paul Crutzen and J. Birks on atmospheric effects.
They re-assessed and re-affirmed the consequences for the ozone layer noted in the 1975 National Academies of Science report (up to 70% of the ozone layer might be destroyed); and drew attention for the first time to the likelihood that large amounts of smoke and dust would be created.
SCOPE figures for winter smoke injection: Temperature drops of 3° to 4° C. Following 1 to 3 years: 25 to 40 % of injected smoke is stabilised in atmosphere (NCAR).

 SGR - Does anybody remember the Nuclear Winter?
During the 1980s, one of the major concerns of the effects of a potential nuclear war was the possibility of it causing a 'nuclear winter' - a catastrophic change in climate caused by the ejection of massive amounts of dust and smoke into the atmosphere during the course of such a war.
In the case of an (e.g.) accidental nuclear exchange between the USA and Russia, the main effects would be felt in the northern hemisphere, as the dust and smoke would quickly circulate across this area.
Altogether, nuclear winter would be an ecological disaster of a similar magnitude to the major extinctions of the past, such as that at the end of the Cretaceous period 65 million years ago when 75% of all species died out, including the dinosaurs.

 WorldNetDaily: Is nuclear war survivable?
Nuclear war would not bring about the end of the world, though it would be horribly destructive.
McElroy said that nuclear winter researchers "stacked the deck" in their study, which was titled "Nuclear Winter: Global Consequences of Multiple Nuclear Explosions" (Science, December 1983).
Nuclear winter is the theory that the mass use of nuclear weapons would create enough smoke and dust to blot out the sun, causing a catastrophic drop in global temperatures.

 nuclear winter
The severities of some predictions of temperature drops and losses of sunlight have been revised downward, but the overall consequences of a large, 5000 megaton exchange of nuclear weapons is still believed to be devastating to the human population of this planet, including huge numbers of people outside the borders of the warring nations.
The potential indirect effects of a large-scale nuclear war could greatly exceed the direct effects, and the substantial majority of the human population would be at risk of global famine resulting from severe reductions in agricultural productivity throughout at least the Northern Hemisphere.
When I first started studying this issue, I was concerned that the dire predictions for global environmental impact were based upon quite a high level of nuclear exchange, 5000 Megatons of nuclear explosives, a significant portion of the current world inventory of nuclear weaponry, delivered in as many as 10,000 separate blasts.

Later models, which took into account additional variables, confirmed the basic conclusions of the TTAPS report and suggested that the detonation of 100 megatons (the explosive power of 100 million tons of TNT) over 100 cities could produce temperature drops ranging from 5 to 15 degrees.
Even a mild 'nuclear winter' could have devastating ramifications for feeding those who survive a nuclear war.

 Preventing an Accidental Nuclear Winter, by Dean Babst, June 28, 2001
Nuclear explosions can also lift an enormous quantity of fine soil particles into the atmosphere, creating more than l00,000 tons of fine, dense, radioactive dust for every megaton exploded on the surface.
A nuclear warhead is far more destructive than is generally realized.

It was thought that severely cold weather would be caused by detonating large numbers of nuclear weapons, especially over flammable targets such as cities, where large amounts of smoke and soot would be injected into the Earth's stratosphere.
This layer of particles would significantly reduce the amount of sunlight that reached the surface, and could potentially remain in the stratosphere for weeks or even years.

 NUCLEAR WINTER AND OTHER MYTHS OF SELF-DETERRENCE
Turco, Toon, Ackermann and Pollack announced their nuclear winter theory to the world in the fall of 1983, they received such an incredible amount of publicity for such an extended period of time that they managed to convince many people that in the event of a nuclear war, nuclear winter would be a reality.
Stu- dies of the discharge rates of manmade and natural smoke and observa- tions of the average amounts of smoke found in the atmosphere, done prior to and since the promulgation of the nuclear winter theory, have shown that smoke particles have an average residence time of one week or less.
One of the main reasons for the proliferation of the belief that a nuclear war cannot be survived is that people who are well known to the public and rightfully respected for their in one area of endeavor, sometimes get involved in other areas about which they know very little.

 Nuclear autumn - new research on the nuclear winter theory Discover - Find Articles
In 1982 atmospheric scientists Paul Crutzen and John Birks warnedthat the pall of smoke from a nuclear war might drastically cool the climate of the earth and lead to the extinction of mankind.
But in February, at a meeting sponsored by the Defense Nuclear Agency, which conducts research on the effects of nuclear weapons, atmospheric scientists suggested that nuclear winter might not be quite so chilling after all.
Schneider calls it ''nuclear fall, not nuclear winter.'' Although Thompson says the consequences of nuclear fall would be ghastly, especially in the Northern Hemisphere, the new research ''doesn't point to human ex- tinction; it wouldn't be the end of the world.''

Voted "other", because I think the million-year ice age model does not take into account the fact that the cloud that causes the nuclear winter will be largely composed of CO from the global firestorms.
Without a more detailed description of what the nuclear war is, it's impossible to estimate what the nature and extent of the nuclear winter would be.
The original nuclear winter was based on something like 150 hydrogen bombs (suitably distributed) all going off at once.

You do not need dust from nuclear explosions, you could just use rockets or supersonic transports or whatever to get the sulfate particles up to the correct height in the atmosphere.
The real problem with this is not nuclear winter and radiation, it is that the human race would be playing G What happens if you miscalculate and put too much reflecting material into the atmosphere and send the Earth not only into nuclear winter but into an ice age?
Since the "nuclear winter" effect is due to the huge clouds of debris thrown up into the atmosphere, we could think of all the dust that has already (and is still being) thrown up by less drastic human and natural activities as providing some of this sheltering effect.
