Can a volcano cause a nuclear winter?
A massive volcanic eruption 250,000 years ago shot dust and ash into the atmosphere and probably caused a winter like that expected by many scientists to follow a nuclear war, according to New Zealand geologists. The New Zealand experts say the Taupo eruption was 1,000 times greater than the 1982 explosion of Mt.
What are the effects of a volcanic winter?
A volcanic winter is a reduction in global temperatures caused by volcanic ash and droplets of sulfuric acid and water obscuring the Sun and raising Earth’s albedo (increasing the reflection of solar radiation) after a large, particularly explosive volcanic eruption.
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.
How do nuclear eruptions affect the climate?
Instead of sulfate particles, like you get from a volcanic eruption, a nuclear event produces soot, and that results in very different climate impacts. Whereas sulfate particles from a volcano might warm the air of the upper atmosphere by a couple degrees, black carbon absorbs heat from the sun and can lead to much more atmospheric warming.
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 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.
