Nuclear winter... about as true as global warming...
Nov 30 2006, 12:08 AM EST
The nuclear winter theory holds even less weight than the global warming theory. How many nukes have been set off without having even a regional climate effect. A nuke doesn't kick up nearly enough dust/ash to cause nuclear winter as popularized in Terminator and The Matrix. As one poster noted; it would take every nuke in the world going off at once to even produce less than one degree of a global climate change.On the other hand, the radiation poisoning is real and would be less than fun. 7 out of 21 found this valuable.

As much as I adore post apocalyptic science fiction incluiding the Matrix, Terminator, On the Beach. Where the wind blows (the David Bowie cartoon), Threads, Testament etc ... we have not had a full scale nuclear attack. The Bulletin of Atomic Scientists certainly has a lot of documentation surrounding the effects of nuclear winter and the history of how nuclear winter became a policy (e.g. political) issue rather than a scientific one ... they are the people that bring you the "doomsday clock" (right now at 7 minutes to zero) ... Global warming is something that is real and even a small seemingly insignificant degree of climate change can produce and has produced tremendous results ... for example this week polar bears have been put on the endangered species list because of the speed at which the ice cap is melting (when a block of ice breaks off it melts faster) a small change in temperature even one degree added to our already warming earth is significant 2 out of 3 found this valuable.

2. No info on Nuclear winter... about as true as global warming...REAL

I live in Jacksonville fl. and this year we didn't even hit a freezing night temp. I have always had to pull the plants and animals in because of dropping temps untill now. I have allergies that come in March, it is the 2nd week of January and guess what? yep i have my allergies,. Global warming is real, now and unstopable. It comes from our transportation, electricity, plastics, and any one thing that we could think of to make our lives he way it is. No stopping the outcome of a hot, weather tortured death of human kind, except for the probability of a nuke. Either way we are screwed!! I guess the Indians had it right all along.

I'm not trying to be rude but Anonymously is completely wrong in his assumption of Nuclear Winter.Nearly all of the studies and models done past and present concerning Nuclear Winter used total weapon yield scenarios of 1000 Megatons to 5000 megatons and some even used 10,000 megatons in the earlier studies when the United States and the Soviet Union had many hundred Multi-Megaton weapons yields in their arsenals. It was assumed these weapons would be detonated nearly simultaneously or within hours of each other. The current total yield of the United States and Russia’s operational nuclear arsenals is approximately 2657 Megatons. This total yield does not include Britain, France, Israel, China, India, and Pakistan. Nuclear Winter effect is caused by the SIMULTANEOUS explosion of several absorption of sunlight when large amounts of soot are injected into the atmosphere by the widespread burning of cities and petroleum stocks destroyed in a nuclear attack, And by large amounts of dirt sucked up by the nuclear explosion themselves. The nuclear fireball itself is on the order of 180 million degrees Fahrenheit. At this temperature everything including concrete, metal, and stone is vaporized into something called ionized plasma. This plasma rises up into the middle and upper levels of the atmosphere and eventually condenses into small particles. Some people call it dust, dirt, or soot. The heavier particles fall to earth very soon after the explosion but the lighter particles are carried into the upper levels of the atmosphere and travel great distances from the point of explosion as what we know as fallout. Similar events have been observed naturally when large volcanic eruptions have injected large amounts of dust into the atmosphere. The Tambora eruption of 1815 (the largest volcanic eruption in recent history) was followed by "the year without summer" in 1816, the coldest year in the last few centuries.
