The capacity to do work, and the central organising challenge of modern civilisation. How we generate, convert, store, and distribute energy shapes economies, ecosystems, and the physical state of the atmosphere.

The sun has been running a fusion experiment for four billion years on the same fuel. Søren Bang Korsholm explains the physics, the engineering challenge of confinement, why fusion cannot run away like fission, and what the history of international collaboration reveals about how large problems actually get solved.
Fusion's greatest achievement is not the plasma temperature or the confinement geometry. It is seventy years of open, international collaboration across the Cold War divide — and what that model reveals about how civilisation-scale problems actually get solved.
The 'root cause' argument against geoengineering research is not scientific caution. It is a form of moral symbolism that mistakes the starting point for the conclusion. Blocking half a percent of sunlight is technically achievable, cost-competitive, and deserves serious parallel investigation.
The Sun's relationship with Earth's climate is one of the most layered problems in planetary science. Christoffer Karoff walks through orbital mechanics, sunspot cycles, measurement difficulties, and the geoengineering options now receiving serious government funding.
