World Nuclear war between two nations could spark global famine

Even a small conflict in which two nations unleash nuclear weapons on each other could lead to worldwide famine, new research suggests. Soot from burning cities would encircle the planet and cool it by reflecting sunlight back into space. This in turn would cause global crop failures that — in a worst-case scenario — could put 5 billion people on the brink of death.

“A large percent of the people will be starving,” says Lili Xia, a climate scientist at Rutgers University in New Brunswick, New Jersey, who led the work. “It’s really bad.”

The research, published on 15 August in Nature Food1, is the latest in a decades-long thought experiment about the global consequences of nuclear war. It seems especially relevant today as Russia’s war against Ukraine has disrupted global food supplies, underscoring the far-reaching impacts of a regional conflict.

Nuclear war comes with a range of lethal impacts, from killing people directly in atomic blasts to the lingering effects of radiation and other environmental pollution. Xia and her colleagues wanted to look at the consequences farther afield from the scene of war, to explore how people all around the planet could also suffer.

They modelled how climate would change in various parts of the world following a nuclear war, and how crops and fisheries would respond to those changes. The scientists analysed six war scenarios, each of which would put different amounts of soot into the atmosphere, and drop surface temperatures from anywhere between 1 and 16 °C. The effects could linger for a decade or more.

    I am reorganizing the site I know nobody will notice but I am not done quite yet but the main forums order has been changed and there is a new news category in Other News which is all the remaining headline news stuff not categorized - Headline News is just the stuff that shows on the main page now and the news archive is off the main forums page
  • The Helper The Helper:
    and the real archive lives off of headline news
