Can we survive a nuclear winter? Peut-on survivre à un hiver nucléaire? ( off-side 33 )

Can we survive a nuclear winter? It is a political, military, cultural, scientific, philosophical and moral issue.
This article is very interesting for all the inhabitants on earth.
Thank you very much, dear friend “nuage”.

The nuclear winter is the nightmare of all those who have studied the consequences of a nuclear conflict. The Cold War belongs to the past, but with Putin on one side and Trump on the other, the world may be on the verge of becoming a very dangerous place again. Nuclear winter would be the result of the millions of tons of smoke, dust and debris propelled into the atmosphere by the explosion of atomic bombs and spreading all around our planet. By masking solar radiation, by destroying the ozone layer, they would condemn to death populations thousands of kilometers away from explosions.

But is it possible, under certain conditions, to survive a nuclear winter, as described in so many books and science fiction films describing a post-apocalyptic universe? This is the question seriously posed by Life Nogginet Gizmodo. The simplest answer is probably no. But in fact it all depends on the countries that lead the nuclear war and even more on the number of bombs that are launched and where they are launched.

Famine and radiation

A “limited” nuclear war with the use of 100 Hiroshima power bombs, for example between Pakistan and India, would result in significant quantities in the order of 3 to 4 million tons Carbon particles propelled above the clouds in the stratosphere from which they could not be “cleaned” by the rains. The smoke would cover the entire globe in less than two weeks and it would take a decade for them to completely disappear. They would absorb some of the solar radiation and would see their temperature approaching 100 degrees Celsius, which would destroy part of the ozone layer. This would translate into almost double the amount of UV that would strike certain regions. In North America and Europe, it would only take a few minutes in June to catch a sunburn.

On the other hand, the temperature would drop across the globe by several degrees, which would have a disastrous impact on the crops. Up to 2 billion people could perish from starvation.


At the end of five years, the temperature on earth would remain on average 1 degree celsius lower than before the atomic war and the ozone layer would remain severely damaged. And this is only the assumption of the use of 100 bombs. There are 15,000 in the arsenals …
“With 100 bombs or less, you may be able to survive the consequences of starvation and exposure to UV radiation,” says Pat Graziosi, who produced the Life Noggin video. “But with a major nuclear war, the nuclear winter would be even more terrible.”

If hundreds or thousands of bombs were launched by the Russians, the Americans, the Chinese … they could send up to 180 million tons of dust into the atmosphere.

They would remain in the stratosphere between 10 and 20 years and the solar radiation would be so reduced that “at noon the light would be that of a full moon night.”

The large agricultural areas of the northern hemisphere would quickly be frozen and the temperature drop would be higher than those of the last ice age 18,000 years ago. The man had then almost disappeared. Again, the survival of the human species would be at stake.

  1. “Qu’est-ce que l’hiver nucléaire?” was the title of an article (par Vladimir Alexandrov, chef du secteur de simulation du clitmat au Centre de calcul de l’Académie des Science de l’U.S.S.R) I read in “Spoutnik” – Digest de la press Sovietique, le numéro Octobre, 1984 . Then, I thought mankind shouldn’t need to survive “a nuclear winter”.
