If nuclear war between Russia and US occurs, it is likely to trigger a 'Little Ice Age'

 The cold war between Russia and the United States is currently at its hottest. Nuclear war could happen at any time, if the two rulers of nuclear weapons really fought openly. Then what will happen to the earth in the event of a nuclear war? New research suggests that if a nuclear war between Russia and the US occurred, it would likely trigger a 'Little Ice Age' lasting for thousands of years. Firestorms will release soot and smoke into the upper atmosphere that will block the Sun and cause crop failures to farmers around the world. In the first month after the explosion, the average global temperature will drop by about 13 degrees Fahrenheit. 




That's more than during the most recent Ice Age, which lasted more than 100,000 years – reducing global temperatures by about 10 degrees Fahrenheit and killing woolly mammoths before ending 11,700 years ago. This study is based on several large-scale and regional computer simulations. Lead author Dr Cheryl Harrison, from Louisiana State University, said: "It doesn't matter who bombs whom. “It could be India and Pakistan or NATO and Russia. Once the smoke is released into the upper atmosphere, it spreads around the world and affects everyone.' However, Russia's invasion of Ukraine has brought the threat of nuclear war to the fore, and this study is the first to provide a clear picture of the environmental impact if Putin were to push the nuclear button.
Nine countries, including the UK, currently control more than 13,000 nuclear weapons, according to the Stockholm International Peace Research Institute. 

Analysis shows sea temperatures will drop rapidly and not return to pre-war states, even after the smoke clears. As the planet gets colder, sea ice will expand to more than six million square miles and up to six feet deep, which in turn will block major ports including Beijing, Copenhagen and St Petersburg. It would then spread to coastal areas that are usually temperate and prevent shipping across the Northern Hemisphere, while getting food and supplies to cities like Shanghai, where ships are not prepared for sea ice, would be difficult. A sudden drop in ocean light and temperature, especially from the Arctic to the North Atlantic and North Pacific, will kill algae - the bedrock of marine food webs. 

The researchers say that fishing and aquaculture will be halted by the creation of 'basically starvation at sea.' One model mimics the US and Russia's use of 4,400 100-kiloton nuclear weapons to bomb cities and industrial estates. In this case, the fires would emit 150 teragrams, or more than 330 billion pounds, of sun-absorbing black smoke and carbon, into the upper atmosphere. Another model shows India and Pakistan detonating 500 100-kiloton nuclear weapons – producing five to 47 teragrams, 11 billion to 103 billion pounds, of smoke and soot. Study co-author Professor Alan Robock, of Rutgers University, said: "Nuclear war has dire consequences for everyone. 

'World leaders have used our previous studies as a push to end the nuclear arms race in the 1980s, and five years ago to pass a treaty at the United Nations to ban nuclear weapons.'
