American scientists have calculated a “nuclear winter” scenario in the event of a war between Russia and the US

A group of scientists from Pennsylvania State University calculated a “nuclear winter” scenario in the event of a potential war between Russia and the United States . The results of the study were published in an article in the journal Environmental Research Letters.

In addition to the immediate consequences of millions of casualties, a nuclear war would have long-term effects on the atmosphere due to the release of about 150 million tons of soot. Experts noted that the air would become less permeable to sunlight, and the temperature on the planet's surface would drop by an average of 15 degrees.

According to the researchers, the "nuclear winter" could last for decades. Corn was taken as a control crop in agriculture. In a bad scenario, its production would decrease by 80 percent, and it would take 7-12 years for the agricultural sector to recover.

Supply chains and trade will also be severely disrupted, further worsening the situation in the agricultural sector and leading to regional or global famine.

The consequences of a war between major nuclear powers would be "catastrophic, with prolonged cold spells, agricultural collapse and social upheaval on an unprecedented scale," the scientists concluded.

Earlier, scientists from the United States found a connection between the position of the hands of the Doomsday Clock, created by the Bulletin of the Atomic Scientists magazine, and the increase in human mortality.
