Oct 20, 2022 · But a few years after a nuclear war, global climatic changes caused by the many nuclear explosions could be responsible for the death of more than half of the human population on Earth.
Aug 15, 2022 · A larger nuclear conflict between Russia and the United States could kill three-fourths of the world’s population in the same timeframe, according to the research published Monday in Nature...

Jun 29, 2023 · A recent scientific paper estimates that over 5 billion people could starve to death, including around 99% of those in the US, Europe, Russia, and China – because most black carbon smoke...

The latest assessment of Russian nuclear military capability estimates that as of early 2022 Russia has a stockpile of approximately 4,477 nuclear warheads — nearly 6,000 if “retired” warheads are included. The US maintains a similar inventoryof 5,500 warheads, with 3,800 of those rapidly deployable. The explosive power of these weapons is difficul...
In 1945 the US attacked the Japanese cities of Hiroshima and Nagasaki with atomic bombs, giving us two real-world examples of the effects of nuclear weapons on human populations. A total of 140,000 people in Hiroshima and 73,000 in Nagasaki died instantaneously or within five monthsdue to the nuclear blast, intense radiant heat from the fireball an...
Prior to the Ukraine war it seemed very unlikely that the superpowers would confront each other again, so many researchers turned to studying the impacts of more limited nuclear conflicts. One studypublished two years ago looked at the likely impacts of a nuclear exchange of about 100 Hiroshima-sized detonations (15 kt yield each) on the most-popul...
If global nuclear famine could result from just 100 nuclear detonations, what might be the result of a fuller exchange of the several thousand warheads held in current inventories by the US and Russia? One 2008 studylooked at a Russia-US nuclear war scenario, where Russia would target 2,200 weapons on Western countries and the US would target 1,100...
Even the 150 Tg soot nuclear war scenario is orders of magnitude less than the amount of smoke and other particulates put into the atmosphere by the asteroid that hit the Earth at the end of the Cretaceous, 65 million years ago, killing the dinosaurs and about two-thirds of species alive at the time. This implies that some humans would survive, eve...
Jul 7, 2022 · The threat of nuclear warfare is back to the forefront following Russia’s invasion of Ukraine. But how would modern nuclear weapon detonations impact the world today? A new research study published today (July 7, 2022) provides startling information on the global impact of nuclear war.
Nov 4, 2022 · A global, all-out nuclear war between the United States and Russia, based on a scenario involving 4,400 100-kiloton weapons, would very quickly result in a minimum of 360 million deaths...
Aug 2, 2023 · A global nuclear war including the US, Europe and China could result in 360 million people dead and condemn nearly 5.3 billion people to starvation in the two years following the exchange. Scientific modelling allows us to peer into the abyss of a nuclear war without having to experience it.
