Would the southern hemisphere survive nuclear war?

Humanity would likely survive, but billions would die of starvation, because with only small-scale agriculture possible in sheltered and powered environments, there would just be not enough food for everyone. So, yeah, it would be kind of safe in the southern hemisphere.

What would happen to the southern hemisphere in a nuclear war?

If, during a major nuclear war, some nuclear weapons were exploded in the Southern Hemisphere (the Ambio study assumed 5569 megatons would be exploded in the Northern Hemisphere and 173 megatons in the Southern Hemisphere12), southern regions affected by local fallout would be contaminated by radioactive iodine-131.

What would be the safest place in a nuclear war?

DO: Find a brick or concrete building, such as a school or office. FEMA identifies brick or concrete buildings as the safest forms of shelter after a nuclear attack. Ideally, the best shelter would have few to no windows and a basement for camping out.

Would a nuclear winter affect the southern hemisphere?

The smoke and dust layer in the atmosphere absorbs incoming solar radiation but is largely transparent to the infrared earth radiation. Further studies indicate that the mid-latitudes of the southern hemisphere could be affected by a war totally confined to the northern hemisphere (Covey et al., 1984).

Would South America be affected by nuclear war?

In other words, the most plausible outcome for full-scale nuclear war is a hellscape in the Northern Hemisphere (where nearly all the major cities are) and a lightly damaged Southern Hemisphere (South America, Australia, the southern third of Africa, New Zealand, many islands).

What US cities would be nuked first?

The Scenario The cities that would most likely be attacked are Washington, New York City and Los Angeles. Using a van or SUV, the device could easily be delivered to the heart of a city and detonated.

Where is the safest place to live in a nuclear war?

The modelled output of our crude atomic plaything produced fallout across the world, which would eventually plunge us into a nuclear winter. So where is the safest place? Our computer modelling shows that should atomic annihilation be on the cards, one of the safest places to live would be Antarctica.

Will the UN’s nuclear weapons ban bring new tensions with Russia?

Although the vast majority of UN member states voted in favour of a ban on nuclear weapons, there are increased tensions between NATO and Russia, continuing volatility between India and Pakistan, and new nuclear nightmares and geopolitical scenarios that never existed during the halcyon days of the Cold War.

What would happen if we had an all-out nuclear war?

Combining this with numerical weather prediction data enabled us to gain an approximate idea of what could happen if we had an all-out nuclear war. The modelled output of our crude atomic plaything produced fallout across the world, which would eventually plunge us into a nuclear winter.

Could the polar regions be used as nuclear hideouts?

It wouldn’t be the first time polar regions have been used as nuclear hideouts: in perhaps the coolest mission of the Cold War, codenamed ‘ Project Iceworm ’, a huge nuclear base was secretly buried deep within the Arctic Circle.
