What would happen if there was an all out nuclear war?

Besides the immediate destruction of cities by nuclear blasts, the potential aftermath of a nuclear war could involve firestorms, a nuclear winter, widespread radiation sickness from fallout, and/or the temporary (if not permanent) loss of much modern technology due to electromagnetic pulses.

Will nuclear war cause extinction?

The bulk of the risk of human extinction from nuclear weapons come from risks of catastrophic climate change, nuclear winter, due to secondary effects from nuclear detonations. However, even in most full-scale nuclear exchange scenarios, the resulting climate effects are unlikely to cause human extinction.

How would nuclear war affect the climate?

Atmospheric impacts of global nuclear war would be more severe than previously thought. Summary: The massive columns of smoke generated by a nuclear war would alter the world’s climate for years and devastate the ozone layer, endangering both human health and food supplies, new research shows.

What would happen if we fought with nuclear weapons?

The smoke from a war fought with strategic nuclear weapons would quickly prevent up to 70\% of sunlight from reaching the surface of the Northern Hemisphere and 35\% of sunlight from reaching the surface of the Southern Hemisphere. Such an enormous loss of warming sunlight would produce Ice Age weather conditions on Earth in a matter of weeks.

What would happen if there was a nuclear winter?

While it is impossible to precisely predict all the human impacts that would result from a nuclear winter, it is relatively simple to predict those which would be most profound. That is, a nuclear winter would cause most humans and large animals to die from nuclear famine in a mass extinction event similar to the one that wiped out the dinosaurs.

Do firestorms cause nuclear winter conditions?

This larger number of firestorms, which are not in themselves modeled, are presented as causing nuclear winter conditions as a result of the smoke inputted into various climate models, with the depths of severe cooling lasting for as long as a decade.

What would happen if there was a global nuclear famine?

Global nuclear famine would ensue in a setting in which the infrastructure of the combatant nations has been totally destroyed, resulting in massive amounts of chemical and radioactive toxins being released into the biosphere.
