Hacking the atmosphere: Geoengineering gets a reality check

Solar geoengineering—the deliberate manipulation of Earth's atmosphere to reduce incoming solar radiation—is moving from theoretical modeling into early-stage real-world experimentation, raising questions that climate science alone cannot answer. The piece traces researchers grappling honestly with the gap between the ambition of atmospheric intervention and the deep uncertainty about its consequences, particularly for regions that had no voice in the decision. It is a sober account of a field where the pressure to act and the pressure to understand are not always moving in the same direction.
