 Australia and New Zealand: The Last Safe Havens in the Event of a Global Nuclear War

The specter of nuclear war remains one of the most terrifying possibilities facing humanity. With rising geopolitical tensions and global instability, experts have long speculated on the consequences of such a catastrophic event—and more importantly, whether any part of the world would remain habitable.

In a chilling report highlighted by the Daily Mail and further analyzed by nuclear expert Annie Jacobsen, author of Nuclear War: A Scenario, the conclusion is stark: in the event of an all-out nuclear conflict, only two places on Earth may remain safe—Australia and New Zealand.

According to Jacobsen, a full-scale nuclear war, particularly one erupting in the Northern Hemisphere, would unleash devastation on a planetary scale. The immediate effects of nuclear explosions would be catastrophic, killing hundreds of millions in what she calls "fireballs." However, the long-term consequences could be even more deadly.

Nuclear Winter and Agricultural Collapse

Jacobsen explains that massive nuclear detonations would ignite widespread fires—engulfing cities, forests, and industrial areas. These fires would pump enormous volumes of smoke and soot into the stratosphere, creating a thick layer of atmospheric particles capable of blocking sunlight for years. This phenomenon, known as nuclear winter, would drastically reduce global temperatures and lead to the failure of agriculture across most of the planet.

Places like Iowa and Ukraine—currently global breadbaskets—would be buried under nuclear-induced snow for up to a decade. Crops would fail, and food supplies would dwindle, resulting in mass starvation. A 2022 study published in Nature Food and cited by Jacobsen estimates that as many as five billion people could die due to famine following a global nuclear conflict.

A World Forced Underground

The loss of sunlight wouldn't be the only challenge. Jacobsen warns that severe damage to the ozone layer would expose Earth's surface to harmful ultraviolet radiation, making outdoor exposure extremely hazardous. Survivors would likely be forced to live underground, struggling to find food and clean air—except, possibly, in two remote and largely self-sufficient countries.

Why Australia and New Zealand?

Jacobsen argues that Australia and New Zealand, both located in the Southern Hemisphere and far from likely nuclear targets, would be spared the worst of the fallout. More importantly, their geographic position and relatively stable climates could allow them to continue sustainable agriculture, even while much of the Northern Hemisphere lies frozen and barren.

These nations also possess the infrastructure and political stability that could help them weather the aftermath of a global catastrophe. Their isolation, once a geographical limitation, may become their greatest asset.

A Warning, Not a Prediction

Jacobsen's work is not meant to induce fear, but rather to underline the importance of global diplomacy, nuclear disarmament, and disaster preparedness. Her book details a hypothetical but scientifically grounded sequence of events that demonstrates how quickly civilization could unravel.

In a world armed with over 12,000 nuclear warheads, the consequences of miscalculation are unthinkable. But as Jacobsen points out, understanding the worst-case scenario may be the only way to prevent it.
