A study published in Nature found that more than 5 billion people would die from starvation following a nuclear war between the U.S. and Russia. A nuclear war between India and Pakistan would result in more than 2 billion people dying from starvation.
The peer-reviewed study led by Rutgers climate scientists examined six nuclear scenarios to understand the potential global death toll not directly linked to nuclear blasts. Researchers discovered that soot and ash entering the atmosphere — or "atmospheric soot loadings" — from burning cities and forests would cause disruptions to the Earth's climate over decades, severely limiting food production and leading to global famine.
