“The study shows that if a large-scale nuclear war broke out
between the US and Russia, billions of the world's population would suffer,
writes UNIAN.
If a nuclear war broke out between the US and Russia, about
99 percent of the warring countries, as well as the population of Europe and
China, would die. Nuclear attacks in other regions could cause catastrophic
events - and completely destroy the structure of society. Such a terrible
scenario is predicted by scientists who have modeled the consequences of war,
writes “The Sun”. A new study from the University of Pennsylvania (USA) modeled
the consequences of a nuclear winter. The study found that 165 million tons of
ash could be released into the atmosphere as a result of a large-scale global
nuclear war. This could act as a catalyst to damage the protective layer of the
atmosphere, the ozone layer, and the ash would block sunlight from reaching the
Earth’s surface. This in turn could affect global food crops and starve
millions of people – up to 99 percent of the population in the United States,
Russia, as well as China and Europe.
The simulations showed that a nuclear war in this case would
have long-term consequences – its effects could be felt for almost a decade.
Even those who survived the direct explosions would risk starving to death as
climate change and destroyed infrastructure would disrupt food supplies. Six to
eight years after a nuclear war, UV-B radiation levels would peak as the ozone
layer would be damaged and global temperatures would drop sharply – bringing
almost all agricultural activity to a halt.
The scientists chose corn, a crop widely grown around the
world, as their subject. Yuning Shi, a crop scientist and meteorologist at
Pennsylvania State University, explained that the researchers modeled corn
yields at 38,572 locations under six nuclear war scenarios.
The scenarios varied in the intensity of emissions. But in
all cases, the fireball caused by nuclear explosions would lead to the
formation of nitrogen oxides in the stratosphere. And nitrogen oxides and the
heat released by the bombs can quickly destroy the ozone layer and increase the
level of ultraviolet radiation at the Earth’s surface. This would damage plant
tissue and severely reduce global food yields. The simulations show that after a
nuclear winter, global corn production could recover in 7 to 12 years, UNIAN
writes.”
