Latest research: If the United States and Russia broke out in a comprehensive nuclear war or cause 5 billion people around the world, the northern hemisphere will enter the "nuclear winter"

↑ After nuclear conflicts occur, the impact of global famine may far exceed the direct effects of the explosion

According to reports, at 0:49 am local time on August 16th, a "militia 3" intercontinental ballistic missile was fired in the Vandenburg Air Force Base in California, USA. The U.S. military said that this test was part of the "routine and regular activities", and its purpose was to show "the preparation status of the US nuclear power."

It is reported that the Russian -Ukraine conflict has once again triggered people's concerns about "nuclear conflicts". A recently released research shows that once nuclear conflicts broke out in the United States and Russia, 5 billion people worldwide will die.

If the United States and Russia broke out of the nuclear conflict

More than half of the world will disappear

According to reports, a study published on Nature Food ("Nature • Food") on August 15 showed that if nuclear conflicts broke out in an all -round way, more than 5 billion people in the world will die in the worst case, that is, global More than half of the population will disappear.

Studies believe that after nuclear conflicts, the impact of global famine may far exceed the direct impact of the explosion. Studies have stated that a large amount of smoke and dust after the explosion will block the sun, destroy the climate system and cause global grain crops to be owed. It is understood that some theories believe that when a large number of nuclear weapons, especially the flammable targets such as cities, use nuclear weapons, which will allow a large number of smoke and smoke to enter the atmosphere of the earth, which may lead to very cold weather. A study published in 2019 predicts that once a comprehensive nuclear conflict broke out, 30%or 40%of the sun will be blocked in the next 6 months, resulting in a significant decline in temperature. "Nuclear winter".

Researchers from the University of Rogers in the United States simulated 6 ways to have nuclear conflicts. The results show that each scenario will bring different numbers of smoke into the atmosphere and will reduce the surface temperature by 1 to 16 ° C, and these impacts may last ten years or longer.

Studies have pointed out that a relatively small nuclear conflict may cause 5 million tons of smoke to enter the atmosphere, resulting in the output of grain crops decreased by 7%within 5 years, and about 27 million people will die directly due to explosion. After two years Famine died.

Once the United States and Russia erupts nuclear conflicts, the situation will be the worst. It is understood that in early 2022, the Russian military nuclear ability assessment is expected to have a total of about 6,000 nuclear warheads in Russia, while the United States has about 5,500 nuclear warheads. Research data show that once a comprehensive nuclear conflict in the United States and Russia occur, it will directly cause 360 ​​million people to die, generating 150 million tons of smoke, resulting in a decrease of 90%of the output of grain crops within three to four years, and nearly 5 billion people may be starved to death. Studies also point out that although the global impact of small -scale nuclear conflicts is relatively small, "once the nuclear conflict begins, it is difficult to control."

It is reported that research also considers the use of crops feeding livestock to support people or to offset some losses by reducing the waste of food, but the conclusion is that in large -scale battles, the impact of these strategies is "minimal". Essence Deepak Ray, a research researcher at the University of Minnesota, believes that this study has an important role in understanding the impact of regional nuclear conflicts on global food, but in reality In order to simulate more accurately. Dpak warned that the probability of this situation was "very, very small", but once it happened, it was a dangerous thing for all mankind. Alan Robock, the co -author of the study, warned that the data told us one thing to prevent nuclear conflicts from occurring.

↑ Bayeng refused to exclude the possibility of using nuclear weapons first under "extreme situations"

Biden: The possibility of using nuclear weapons without exclusion

Putin: There will be no winners in the nuclear war

It is reported that the upgrade of Russia and Ukraine's conflict has once again aroused concerns about "nuclear conflicts". According to a March report, US President Biden stated that he refused to exclude the possibility of using nuclear weapons first under "extreme situations." It is reported that Biden was abandoning his vows of "changing the US long -term nuclear strategy" campaign and instead accepting existing policies, that is, the United States first used the power to use nuclear weapons under the circumstances of "severe non -nuclear strategy attacks".

It is reported that since the Cold War, the United States has allowed first use nuclear weapons under the "extreme situation", such as the invasion of conventional troops, or chemical and biological attacks. During the presidential campaign in 2020, Biden promised to promote the formulation of a policy, that is, the "only purpose" of the US nuclear arsenal will be to prevent or retaliated with the enemy's nuclear attack. However, the "only purpose" principle proposed by Biden has caused concerns about many allies. Some insiders said that after the outbreak of the Russian and Ukraine conflict, because he didn't want to make himself too weak, and the pressure of NATO allies, Biden decided to give up his "only purpose" vow.据悉，美国新版《核态势评估报告》中，对核武器的使用策略表述已变为“美国只有在为保护美国或盟友伙伴国的重大利益的极端情况下，考虑使用核武器。”分析指出，这一There are "strategic fuzzy" in the expression, which actually lowered the "nuclear threshold" in the United States.

In June, Modvedev, vice chairman of the Russian Federal Security Conference, said in an interview that the idea of "impossible nuclear war" was wrong, but the nuclear war means that the end of humans, and human beings should do everything to avoid nuclear war.Russian President Putin said on August 1 that there will be no winners during the nuclear war, and the nuclear war should not be launched.According to reports, on January 3, 2022, the five nuclear weapons leaders jointly issued the "Joint Statement on Preventing Nuclear War and Avoiding the Army Competition", emphasizing that the nuclear war can not win or not, reiterated that the nuclear weapons will not target each other or each other orAny other country.
