International Physicians for the Prevention of Nuclear War (IPPNW) has conducted several studies on the impact nuclear weapons would have on the atmosphere, climate, and food production.
A most recent study comes to the conclusion that the ‘nuclear winter’ following a limited nuclear change would be more destructive than previously thought.
“The soot (5 teragrams of black carbon, initially) gets lofted higher and persists longer—at least 15 years instead of the 10 previously calculated. Global average cooling is more extreme and persists longer—two decades or more—because of thermal inertia in the oceans after “more than a decade of prolonged cooling.” Drops in precipitation rates are not quite as steep during the first five years, compared with the previous studies, but in year five they continue to fall and are still down 4.5% at the end of a decade, when the earlier models were already showing a recovery.”
