Full-scale nuclear war may kill 5 billion people

In a modern nuclear war, five billion people will perish, but the impact of global starvation induced by sunlight-blocking pollution will likely far outweigh the losses inflicted by the explosions, Bloomberg reported, quoting a study.

Rutgers University scientists drew out the im-pacts of six potential nuclear conflict scenarios. The worst-case scenario, a full-scale conflict between the United States and Russia, would wipe out more than half of humanity, according to the study published in the journal Nature Food.

The figures were based on estimations of how much soot would enter the environment from con-flagrations caused by nuclear weapons and explo-sion. Researchers used a climate forecasting tool endorsed by the National Center for Atmospheric Research to evaluate crop yields on a country-by-country basis.

Even a very minor battle would have disastrous effects on the world food supply. The study indicated that a localised conflict between India and Pakistan would result in a 7% drop in food yields within five years, while a conflict between the United States and Russia would result in a 90% decline within three to four years.

Researchers also evaluated whether repurposing crops currently used as animal feed or minimising food waste could mitigate losses in the early after-math of a war, but determined that the savings would be negligible in larger conflicts.

Following Vladimir Putin’s invasion of Ukraine, the possibility of conflict between the United States and Russia has been raised, prompting the publica-tion of this report. In April, Russian Foreign Minister Sergei Lavrov warned that a “serious” risk of nuclear conflict existed.

Alan Robock, co-author of the paper and profes-sor of climate science in the Department of Envi-ronmental Sciences at Rutgers University, stated, “The numbers tell us one thing. We must prevent a nuclear war from ever happening.”—AFP
