“Limited” Nuclear War Would Result in Abrupt Climate Disruption and Global Starvation

New scientific work demonstrates that even a “limited” nuclear war would cause abrupt climate disruption and global starvation.  A limited nuclear war is defined as a conflict confined to one region and involving a small fraction of the world’s nuclear arsenals. But such a conflict would be neither limited nor regional and despite statements to the contrary, it would be an event on a planetary scale of death and destruction.  Global food insecurity and famine from reduced crop, marine fishery and livestock production due to climate disruption from nuclear war soot injection.  https://www.nature.com/articles/s43016-022-00573-0

The Nobel Peace Prize awardee in 1985 was the International Physicians for the Prevention of Nuclear War.  https://www.ippnw.org/  The Physicians summarized the new report by the Rutgers-led international research team, headed by Lili Xia, which clearly demonstrates that there is no such thing as a minor or small nuclear war.  The damage would be catastrophic.  https://ippnweupdate.files.wordpress.com/2022/08/nuclear-famine-2022.pdf

The researchers established six possible scenarios for a limited nuclear war in an urban area based on a 2010 world population of 6.7 billion people.  The number of weapons used in the scenarios varied from 100 to 4,400 with an explosive range of 15 to 100 kilotons resulting in five to 150 million metric tons of fallout soot, which would cool the planet.  The scientists estimate that 27 million to 360 million people would die directly from the bomb blasts.  After two years of famine, the number of people in danger of death would range from 255 million to over 5 billion – or three out of four people.  https://www.nature.com/articles/s43016-022-00573-0

In their summary, the Physicians concluded by saying, “In the case of a nuclear war, there is no possible treatment after the fact.  We must focus on prevention.  And the only way to ensure that nuclear weapons are never used is to eliminate them completely.  The United Nations Treaty on the Prohibition of Nuclear Weapons, adopted by the United Nations General Assembly on July 7, 2017, and which entered into force on January 22, 2021, provides the legal and moral foundation for the eradication of nuclear weapons. https://www.un.org/disarmament/wmd/nuclear/tpnw/

In the interest of public health, [the International Physicians for the Prevention of Nuclear War] thus present this summary of important new data about a potential species-level threat to humanity.  The cure for this is prevention.  The prevention is to renounce and abolish nuclear weapons.”  https://ippnweupdate.files.wordpress.com/2022/08/nuclear-famine-2022.pdf
