In a nuclear winter scenario, soot would block the sun, causing global agricultural failure. Climate models from Professor Brian Toon indicate that only Australia and New Zealand would likely remain capable of sustaining agriculture, making them the only viable locations for long-term survival.

Tech billionaire Bill Gates supports a radical concept called solar radiation management: releasing aerosols to reflect sunlight and cool the planet. This moves the idea of a "sun visor for Earth" from science fiction to a seriously considered, albeit controversial, last-resort solution for climate tipping points.
While a major contributor to emissions, the agricultural industry is also more vulnerable to climate change impacts than almost any other sector. This dual role as both primary cause and primary victim creates a powerful, intrinsic motivation to innovate and transition from a "climate sinner to saint," a dynamic not present in all industries.
While often romanticized, a widespread shift to pre-industrial, low-yield organic farming would be a climate disaster. The core environmental problem of agriculture is land conversion. Since organic methods typically produce 20-40% less food per acre, they would necessitate converting massive amounts of forests and wildlands into farmland, releasing vast carbon stores.
The way we grow food is a primary driver of climate change, independent of the energy sector. Even if we completely decarbonize energy, our agricultural practices, particularly land use and deforestation, are sufficient to push the planet past critical warming thresholds. This makes fixing the food system an urgent, non-negotiable climate priority.
The true horror of nuclear war isn't the initial blast but the complete breakdown of society. With no government, law, or resources, survivors face a primal, violent struggle for existence amidst sickness and malnourishment, making immediate death a preferable fate.
The immediate aftermath of a nuclear strike isn't just a blast. It's a thermonuclear flash creating a massive firestorm, a bulldozing wind effect that levels buildings, and intense radiation, followed by a conflagration of mega-fires from thousands of simultaneous strikes.
The environment has become the number one security issue, manifesting as climate change. In the developing world, this drives migration from unsustainable rural areas to overburdened megacities. This massive, unchecked urbanization creates immense governance challenges and directly fuels populist movements in destination regions like Europe, making it a central factor in global instability.
Despite nuclear power's poor public image based on fission, significant advances in fusion technology are positioning it as a potential solution for clean, abundant energy. We may look back on 2026 as the year this shift became viable.
Storing seeds in vaults like Svalbard is a flawed backup plan because they are not adapting to new diseases and a changing climate. True resilience comes from cultivating diverse crops in the field, allowing them to co-evolve with threats and develop natural resistance.
The onset of a La Niña weather pattern is occurring unusually late in the year, coinciding directly with the planting season in Brazil and Argentina. This timing is critical because the associated dry conditions threaten yields in a region that China increasingly depends on for soybeans due to the US trade war.
